Drive to the intersection of North Mountain Avenue and the Rillito River bridge in midtown Tucson, park at Brandi Fenton Memorial Park on the river's north bank, and step out onto a paved twelve-foot-wide shared-use path that runs east toward Craycroft Road and west toward Interstate 10. From this single trailhead, a rider can pedal more than 20 miles east through the Pantano Wash corridor toward Vail, more than 30 miles west and north through the Santa Cruz River corridor to Marana's Crossroads at Silverbell District Park, or roughly 15 miles north through the Cañada del Oro Wash corridor into Oro Valley and James D. Kriegh Park — all without sharing a single foot of asphalt with a motor vehicle. Per Pima County Natural Resources, Parks and Recreation (NRPR), this is the Chuck Huckelberry Loop — "The Loop" — and it now exceeds 137 paved, car-free miles. Per Visit Tucson and the League of American Bicyclists, the Loop is the single asset most often cited when Tucson is ranked among the country's most bike-friendly metros and the structural reason the city holds a Gold-Level Bicycle Friendly Community designation. As the metro enters June 2026, the Loop becomes the region's most useful free family asset — but it has to be used on the Sonoran Desert's terms, in the first three hours of daylight. Here is the May 31, 2026 sourced walk-through. 137+ mi — Paved, car-free Loop miles per Pima County NRPR. 5 cities — Tucson, Marana, Oro Valley, South Tucson, Sahuarita. $0 — Use fee — the Loop is free and open 24/7. Gold — Tucson's League of American Bicyclists ranking What "The Loop" Actually Is Per Pima County Natural Resources, Parks and Recreation (pima.gov/nrpr), The Chuck Huckelberry Loop is a paved, shared-use, car-free path system threaded through the flood-control corridors of the Tucson metro's six major river and wash channels — the Rillito River, the Santa Cruz River, the Cañada del Oro Wash, the Pantano Wash, the Julian Wash, and the Harrison Greenway. The Loop sits on a backbone of Pima Regional Flood Control District easements: the path is built atop the maintenance levee on the top of bank of each channel, which is why the Loop crosses through five jurisdictions — the City of Tucson, the Town of Marana, the Town of Oro Valley, the City of South Tucson, and the Town of Sahuarita — without ever sharing a roadway with motor traffic. The path is twelve feet wide along most segments, paved with asphalt, and signed for bicycles, pedestrians, runners, equestrians (in segments where horse access is permitted), and other non-motorized users. Per Pima County NRPR, electric-assist bicycles are permitted; motorized vehicles of any other type are not. The full network is open 24 hours a day and is free to use; no permit or pass is required at any trailhead. The system was formally renamed The Chuck Huckelberry Loop in 2021 by the Pima County Board of Supervisors in recognition of former Pima County Administrator Chuck Huckelberry's role in planning and funding the system over several decades; most Tucsonans still call it "the Loop." The Six Major Segments Per Pima County NRPR's published interactive Loop map (webcms.pima.gov/cms/One.aspx?portalId=169&pageId=66486) and the printable system map, the Loop is structurally organized around six named river and wash corridors. Picking the right segment for a given household depends on where the house is, where the path connects, and which direction the morning sun is hitting the levee. Rillito River Park (~12 mi, Midtown–Foothills, Brandi Fenton): The Loop's most-used segment runs along the Rillito River from Craycroft Road on the east through Campbell Avenue, Mountain Avenue, and First Avenue to the Santa Cruz River confluence on the west. Per Pima County NRPR, the segment is roughly 12 miles long, anchored by Brandi Fenton Memorial Park at 3482 E. River Road, with picnic ramadas, restrooms, a splash pad, an off-leash dog park, and the Loop's flagship Brandi Fenton Fitness Court. This is the segment most Catalina Foothills, Casas Adobes, and central Tucson households reach in under ten minutes. Santa Cruz River Park (~30+ mi, Marana–South Tucson, Christopher Columbus): The Loop's longest north-south spine runs along the Santa Cruz River from Marana's Crossroads at Silverbell District Park area on the north through the Christopher Columbus Park trailhead at 4600 N. Silverbell Road and continues south through downtown-adjacent Tucson and the City of South Tucson toward the San Xavier District. Per Pima County NRPR, the Santa Cruz River segment is the longest individual corridor in the Loop and connects the largest number of cross-jurisdiction trailheads. Christopher Columbus Park, on the river's east bank, is the most-used west-side trailhead. Cañada del Oro River Park (~15 mi, Oro Valley, Kriegh & Riverfront): The Loop's northern spur runs along the Cañada del Oro Wash from the Rillito River confluence near La Cañada Drive through Casas Adobes and into the Town of Oro Valley, anchored by James D. Kriegh Park at 23 W. Calle Concordia and Riverfront Park at 551 W. Lambert Lane. Per the Town of Oro Valley Parks and Recreation Department and Pima County NRPR, the segment is the cleanest single read on Oro Valley's family-park-and-trail integration and is one of the most popular cool-morning runner segments in the metro. Pantano + Julian Wash + Harrison Greenway (~30+ mi, East–Southeast, Vail Adjacent): The Loop's east and southeast corridors run along the Pantano Wash from the Rillito confluence south through midtown and east-side Tucson, then along the Julian Wash through south Tucson and the Drexel Heights and Valencia corridors, and connect via the Harrison Greenway segment toward the east side near the Vail and Rita Ranch areas. Per Pima County NRPR, these corridors collectively add roughly 30-plus miles of connector path and are the structural reason the Loop closes into a continuous "loop" rather than four separate spurs. Quick reference: The Chuck Huckelberry Loop — 137-plus paved, car-free, shared-use miles managed by Pima County Natural Resources, Parks and Recreation along the Rillito, Santa Cruz, Cañada del Oro, Pantano, Julian Wash, and Harrison Greenway corridors. No use fee. Open 24/7. Major trailheads: Brandi Fenton Memorial Park (Rillito, 3482 E. River Road), Christopher Columbus Park (Santa Cruz, 4600 N. Silverbell), James D. Kriegh Park (Cañada del Oro, 23 W. Calle Concordia, Oro Valley). Electric-assist bicycles permitted; other motorized vehicles not allowed. Interactive map at pima.gov/nrpr. Why the First Three Hours of Daylight Are the Summer Window Per the National Weather Service Tucson office (weather.gov/twc) and its Tucson monthly normals page, average June high temperatures in Tucson run around 100°F, with the daily peak typically hitting between 3:00 and 5:00 p.m. Morning lows in early June average in the high 60s to low 70s and climb steadily through the month as the monsoon moisture window approaches. The North American Monsoon's official start date is June 15, and afternoon thunderstorms with strong outflow winds, blowing dust, and lightning become a daily possibility from mid-June through mid-September. The practical implication for the Loop is that, from roughly the first week of June through Labor Day, the comfortable use window collapses to the first three hours of daylight — call it 5:30 a.m. to 8:30 a.m. — and the late-evening window after sundown. Asphalt surface temperatures on the levee track higher than ambient air temperatures, which compresses the comfortable window further for dog-walkers; per the Humane Society of Southern Arizona and the City of Tucson, pavement temperatures above 125°F can burn paw pads, and the Loop's exposed asphalt surface routinely exceeds that threshold by mid-morning in July. The cleanest summer playbook is a single rule: be off the Loop by 9:00 a.m., or wait for the post-sunset window. Trailheads, Restrooms, and the Fitness Court Network Per Pima County NRPR, the Loop is anchored by a network of more than two dozen designated trailheads, most of which are inside Pima County or municipal parks with on-site parking, water fountains, and ADA-accessible restrooms. The three highest-volume trailheads — Brandi Fenton Memorial Park on the Rillito, Christopher Columbus Park on the Santa Cruz, and James D. Kriegh Park on the Cañada del Oro — each combine large paved parking lots, restrooms, water, and direct levee access on a flat grade. Brandi Fenton additionally hosts the Loop's flagship National Fitness Campaign Fitness Court — a free outdoor circuit-training installation funded in part by the City of Tucson's parks bond and aligned with the National Fitness Campaign's adult fitness programming standards. Per the City of Tucson Parks and Recreation Department, the Brandi Fenton Fitness Court is open to the public, free to use, and paired with the Fitness Court app, which guides users through seven movements at three difficulty levels. Other significant trailheads include Curtis Park (Rillito east), Christopher Columbus's south parking area (Santa Cruz), Riverfront Park (Cañada del Oro at Lambert Lane in Oro Valley), Naranja Park (Cañada del Oro spur, Oro Valley), and Quincie Douglas Park (Julian Wash, south Tucson). The full trailhead inventory and a printable map are available on the Pima County NRPR Loop page. Two Events Worth Putting on the Calendar Two annual Loop events frame the system's community calendar. First, per Living Streets Alliance and Pima County NRPR, the Loop the Loop ride is a community-organized fully-supported recreational ride that takes participants around as much of the Loop's full perimeter as their pace allows in a single day, with rest stops, snacks, and route support; the event typically runs in the cool-weather shoulder months, and Living Streets Alliance is the cleanest source for the 2026 ride date and registration. Second, per the El Tour de Tucson organization, the El Tour de Tucson century ride — the largest perimeter bicycle event in the metro and one of the largest in the country — uses substantial portions of the Loop as part of its November race route, with roughly 9,000 riders annually across the 102-mile, 64-mile, 32-mile, and 12-mile distances. Per El Tour de Tucson, the 2026 ride is scheduled for Saturday, November 21, 2026, with registration open at perimeterbicycling.com. The practical implication for a June 2026 household is that the Loop is not just a daily-use path but a year-round community-event venue worth keeping on the fall calendar. Quick summer-morning playbook: park at Brandi Fenton Memorial Park, Christopher Columbus Park, or James D. Kriegh Park; bring at least 32 ounces of water per person, electrolytes, sun protection, and a refillable bottle for the on-site fountains; ride or walk in the first three hours of daylight; turn around when the surface starts to bake or pavement temperatures exceed pet-safe thresholds; check NWS Tucson and the Pima County NRPR Loop alerts page for any wash-crossing closures after a monsoon event. The Loop is a shared-use path — bicycles yield to pedestrians and horses, and standard "call your pass" etiquette is recommended. How the Loop Got Built — and Why It Keeps Growing Per Pima County NRPR, the Loop's structural origin is the Pima Regional Flood Control District's mid-1980s decision, following major flood damage along the Rillito and Santa Cruz corridors, to acquire top-of-bank easements and improve channel maintenance access along the metro's river and wash corridors. The recreation overlay — paving the maintenance road for shared-use access — was added incrementally over the following three decades, accelerated by Pima County General Obligation Bond programs and by Regional Transportation Authority (RTA) Plan 1 voter-approved funding for trailheads, undercrossings, and connection links. Per the Pima Association of Governments and the RTA (rtamobility.com), RTA Plan 1 dedicated capital to closing Loop gaps at major arterial undercrossings, which is how the system now passes under roadways such as Ina Road, Orange Grove Road, and Sunrise Drive without forcing users into traffic. The RTA Next ballot question — the proposed successor program voters considered in recent cycles — included additional Loop expansion as a programmed line item. The practical implication is that the Loop's 137-plus current miles are not a finished system; per Pima County NRPR's published Loop expansion plan, additional connection links and Loop-adjacent neighborhood spur paths are programmed for delivery through the late 2020s and early 2030s. The Real-Estate Adjacency Read For Tucson buyers, sellers, and relocation households, the Loop is one of the few non-school, non-mountain amenities that consistently shows up in price-per-square-foot premiums on adjacent inventory. Properties with direct or near-direct Loop access — defined here as within a quarter mile of a trailhead or with private gate access to the levee — tend to clear above the surrounding submarket median per Realtor.com and Redfin listing data, particularly in the Catalina Foothills (Rillito segment), Casas Adobes and the Skyline corridor (Cañada del Oro segment), Continental Reserve and Continental Ranch in Marana (Santa Cruz segment), and Riverfront Park-adjacent inventory in Oro Valley (Cañada del Oro segment). Per Visit Tucson, the Loop is one of the consistently cited reasons relocation buyers choose Tucson over comparable Sun Belt metros — "I can ride to work from Marana to downtown without touching a car" is a real conversation that happens on the Loop most weekday mornings. For sellers, Loop access is a durable lifestyle line item that has held value through multiple market cycles, regardless of where mortgage rates have sat in any given quarter. The right neighborhood, price point, and house-by-house answer is always a conversation, not a checklist — but for many relocation buyers, walking or riding a segment of the Loop on the morning of a home tour is the single most useful pre-decision exercise on the metro. Three Cool-Morning Itineraries for the First Two Weeks of June For households building a first-time Loop weekend, three itineraries cover most use cases without overcommitting before the daily heat sets in. First, the Brandi Fenton 6:30 a.m. family loop: park at Brandi Fenton Memorial Park, walk or scooter the paved Rillito path east toward Craycroft Road for roughly a mile, turn around, and finish at the Fitness Court and splash pad. Total time about 90 minutes, total cost zero. Second, the Christopher Columbus to Sweetwater Wetlands sunrise ride: park at Christopher Columbus Park at 4600 N. Silverbell Road, ride the Santa Cruz path roughly 2.5 miles north to the Pima County Sweetwater Wetlands at 2667 W. Sweetwater Drive, walk the wetland's separate interpretive loop (a Tucson Audubon-recommended birding site), and ride back. Total time about two hours. Third, the Oro Valley Kriegh-to-Riverfront cool-morning run: park at James D. Kriegh Park at 23 W. Calle Concordia in Oro Valley, run the Cañada del Oro path north past La Cholla Boulevard to Riverfront Park at 551 W. Lambert Lane, then turn around for a roughly six-mile out-and-back with restroom and water access at both endpoints. Each itinerary fits inside the first three hours of summer daylight and ends before the asphalt starts to bake. What's Coming on the Loop in June and the Rest of 2026 Per Pima County NRPR and Living Streets Alliance, the next several months on the Loop's community calendar include the standard summer programming pause for the dog-days heat, with the major community ride windows resuming as temperatures drop through October. Per El Tour de Tucson and Perimeter Bicycling Association of America, El Tour de Tucson 2026 is scheduled for Saturday, November 21, 2026; the ride traditionally uses Loop segments along the Rillito and Santa Cruz corridors, and route maps are released at perimeterbicycling.com. Per Pima County NRPR's published Loop news page, ongoing capital projects — including additional connection links, levee resurfacing, and shaded rest-stop installations funded by Pima County and RTA dollars — are programmed across multiple segments through the end of 2026. For Loop users planning extended summer rides, the cleanest single source for surface closures, maintenance work, and post-monsoon detour notices is the Pima County NRPR Loop alerts page at pima.gov/nrpr. Quick orientation: The Chuck Huckelberry Loop, managed by Pima County Natural Resources, Parks and Recreation. 137-plus paved, car-free, shared-use miles. Free, 24/7. Major trailheads: Brandi Fenton Memorial Park (3482 E. River Road, Tucson — Rillito), Christopher Columbus Park (4600 N. Silverbell Road, Tucson — Santa Cruz), James D. Kriegh Park (23 W. Calle Concordia, Oro Valley — Cañada del Oro). Summer cool-morning window: roughly 5:30 to 8:30 a.m. Bring water, sun protection, and check pavement temperatures before bringing pets. Interactive map and trailhead inventory at pima.gov/nrpr. What It Means for Locals, Buyers, and Sellers For Tucson, Marana, Oro Valley, South Tucson, and Sahuarita households, the Loop is the single most-used, lowest-cost public amenity in the metro and the closest thing the region has to a year-round community gathering corridor. June 2026 is the moment in the calendar when the system shifts from all-day use to a dawn-to-mid-morning-only window — and households new to the desert who learn that rhythm in their first June tend to use the Loop more, not less, through the long summer. For relocation buyers visiting Tucson on a fact-finding trip, a sunrise walk along the Rillito at Brandi Fenton or along the Cañada del Oro at Riverfront Park is one of the cleanest single-morning reads on how the metro actually feels on a workweek morning. For sellers in submarkets directly adjacent to a Loop trailhead or with private levee access — the Catalina Foothills along the Rillito, Casas Adobes along the Cañada del Oro, Continental Ranch and Continental Reserve along the Santa Cruz, and Riverfront-adjacent Oro Valley inventory — Loop proximity is a durable, well-understood lifestyle line item that has held value across multiple market cycles. As always, the right neighborhood, price point, and house-by-house answer is a conversation, not a checklist.
