The Prescott Circle Trail is a 54-mile loop around the town of Prescott, Arizona, a "mini thru-hike" through ponderosa pine forests, granite boulder fields, and high desert terrain. Elevation runs from 5,140 to 6,990 feet with about 6,000 feet of cumulative gain, which makes for a solid 2-3 day trip without the commitment of a longer expedition. The route passes the Granite Dells at Watson Lake, three reservoirs (Watson, Willow, and Goldwater Lakes), and viewpoints of Granite Mountain and Thumb Butte. It is a multi-use trail shared with mountain bikers and equestrians, with moderate traffic, yet it feels surprisingly remote despite passing within three miles of downtown Prescott. Counterclockwise is the preferred direction: you start with the forested eastern sections at higher elevations, then descend through the more exposed terrain on the western side.
No permit is required for hiking the Prescott Circle Trail. Parking fees apply at most trailheads: City of Prescott trailheads charge $3 per vehicle at kiosks (free on Wednesdays), or you can buy an annual pass online. Prescott National Forest trailheads require either a day-use fee or an America the Beautiful/Interagency Pass. For overnight trips, leave a visible note on your dashboard saying how long you will be away. Overnight parking is generally not allowed at City trailheads but is permitted at National Forest trailheads with that notification.
Camping is restricted in the Prescott Basin area; you cannot camp wherever you want. Camping and campfires are only allowed at designated dispersed campsites (marked by signs, limited to within 300 feet of specified forest roads) or at developed campgrounds. The three established campgrounds along the trail are Watson Lake, Yavapai (Granite Basin), and White Spar. Reservations through Recreation.gov are recommended, though first-come-first-served sites exist. Camping is limited to 14 days in any 30-day period on the National Forest (7 days in the Prescott Basin proper). Campfires are permitted only in provided fire rings, using only dead and down wood. During fire restrictions (typical in dry periods), campfires may be prohibited entirely. Bear canisters are not required, but proper food storage is essential.
April, May, September, and October have the best conditions for backpacking the Prescott Circle Trail. Late April through May brings comfortable temperatures (daytime highs 67-75°F, nighttime lows 34-40°F), minimal rainfall, and often wildflowers at the higher elevations. September marks the end of monsoon season and the most stable weather of the year: warm days, cool nights, and clear skies. Early October extends this window as fall colors begin to appear.
Summer (June-August) is hot, with daytime temperatures in the low-to-mid 80s and intense sun on the exposed western sections. The monsoon season (July-August, peaking in August) brings predictable afternoon thunderstorms with heavy rain, lightning, hail, and flash flood danger. It is a poor time for a thru-hike, though manageable with early starts and a flexible schedule. Lightning risk on exposed ridgelines is significant during afternoon storms.
Winter (November-March) is possible for experienced backpackers who can handle snow travel and long water hauls. Snow and ice sit on north-facing sections, particularly above 6,500 feet. Daytime temperatures range from 50-60°F, with nighttime lows of 28-39°F. The main problem is water: campground spigots are shut off November 1 through March 31, and some trail fountains (like Peavine) are winterized. March and November have hiking-friendly temperatures but still require careful water planning.
Water is the biggest logistical challenge on the Prescott Circle Trail. Only a few reliable potable sources exist: drinking fountains at Pioneer Park (mile 12.3), Goldwater Lake (unreliable because of vandalism-related shutoffs), the Peavine parking area (shut off for winter), and the developed campgrounds. White Spar and Yavapai campgrounds have water seasonally from May through October; these sources are turned off November through April.
Natural water near the lakes (Watson, Willow, Goldwater, Lynx) is the most dependable, though it all needs filtration or treatment. Seasonal reliability swings widely: spring snowmelt and the post-monsoon period (September) bring better natural water, while late spring and early summer can be very dry. Many backpackers report carrying 4-6 liters between reliable sources in dry seasons, and some cache water for the longer stretches.
Resupply is straightforward because the trail stays close to Prescott. Downtown Prescott has multiple grocery stores including Safeway (1044 Willow Creek Rd, 10 minutes from downtown) and Natural Grocers, plus a full-service REI store for gear. Sportsman's Warehouse near Thumb Butte also carries camping supplies. The trail comes within three miles of downtown at its closest point, so a mid-trip resupply is feasible. Most 2-3 day thru-hikers simply carry all their food from the start.
Rattlesnakes are active March through October, most often at dawn, dusk, and increasingly at night as temperatures rise in late spring and summer. They are not aggressive but will defend themselves if surprised. Use trekking poles to probe vegetation and rocks, keep hands and feet out of spots you cannot see, and stay 10+ feet away if you meet one. Black bears and mountain lions live in the area, with recent sightings reported near Prescott Valley. Make noise, avoid hiking alone or at dawn and dusk, and carry bear spray. If you encounter a mountain lion, make yourself large, maintain eye contact, do not run, and fight back aggressively if attacked.
Afternoon thunderstorms during monsoon season (July-September) bring lightning danger, especially on exposed ridgelines and the western sections with little tree cover. Start early and plan to be off the high points by early afternoon. Flash flooding can occur in drainages during heavy rain.
Navigation takes attention despite generally good signage. The trail is marked with round Prescott Circle Trail logos at junctions, but some sections have inconsistent marking. Multiple trail users report missing turnoffs and getting off-route 2-3 times, particularly where many trails intersect. Download offline maps, carry a GPS device or a phone with GPS, and verify your location at each junction. The Boycott Trail section is considered the most technical, following a rocky downhill streambed.
Heat exposure on the western and southern sections can be severe in summer. Juniper and low scrub provide far less shade than the ponderosa forests on the eastern side, so carry extra water and sun protection for these segments.
The 2022 Crooks Fire temporarily closed portions of the trail near Goldwater Lake and Watson Lake. Check the Prescott National Forest alerts page before your trip for current closures related to fire, prescribed burns, or powerline construction.
Prescott sits in central Arizona, approximately 100-110 miles north of Phoenix. The nearest major airport is Phoenix Sky Harbor International Airport (PHX), about 2-2.5 hours away by car. Prescott also has a small regional airport, Ernest A. Love Field (PRC), with limited commercial service.
Groome Transportation runs daily shuttle service with 23+ scheduled round trips between Phoenix Sky Harbor and Prescott, with door-to-door service by advance reservation (book 36 hours ahead by calling 928-350-8466 or online). Other shuttle options include Airport Shuttle of Phoenix, Northern Arizona Limousine, and Fly-U Shuttle. Most backpackers will want to rent a car at the Phoenix airport for flexibility in reaching trailheads and shopping for supplies.
The Prescott Circle Trail has 15 trailheads spaced around the loop, so access is easy whether you are day hiking or starting a thru-hike. Popular starting points for counterclockwise thru-hikes are Yavapai Campground in Granite Basin and Watson Lake. Most trailheads have adequate parking, though the popular lots can fill on weekends. City trailheads charge a day fee; National Forest trailheads accept the Interagency Pass. Roads to the trailheads are generally good and fine for passenger vehicles, though some dispersed camping access roads require high clearance.
Start counterclockwise from Yavapai Campground or Watson Lake to get the forested, shaded eastern sections at higher elevations first, saving the more exposed western terrain for when you have hit your stride. This direction also lines up with prevailing weather patterns and puts better morning light on the Granite Dells.
For a 3-day itinerary, camp at Yavapai Campground (or nearby designated dispersed sites) after day one and White Spar Campground after day two, which breaks the loop into roughly 18-mile segments. Reserve campsites in advance during peak season (April-May, September-October), since first-come sites fill quickly on weekends. For a 2-day speed hike, fit backpackers can push 27 miles per day, camping once at White Spar.
The Granite Dells at Watson Lake are the highlight, so plan time to linger and explore the boulder formations. The birding on the north side of Willow Lake is excellent during spring and fall migration. If you have time, the side trail to the Granite Mountain summit is worth the extra miles for the views.
Cache water in advance if attempting the trail during the dry season (late May-June) or in winter when campground water is off. Some hikers stash gallon jugs at road crossings where the trail is reachable by car. Carry at least 4-6 liters between reliable sources in dry conditions.
Trail intersections can be confusing, so download offline maps to your phone and enable GPS tracking. Cell service is generally good near town but spotty in the remote sections. The MTB Project app has detailed trail maps and is popular with local mountain bikers, who can share current conditions.
Stay off the trail during active fire restrictions or immediately after wildfires. Check the Prescott National Forest website for current alerts and closures before departing. Prescribed burns occur periodically in the forest and sometimes cause temporary closures or smoky conditions.
Bring trekking poles for the Boycott Trail section and for probing around rocks and vegetation where rattlesnakes may hide. The trail surface varies from smooth singletrack to rocky, technical sections, so ankle support and sturdy footwear are recommended.
If you need a mid-trip resupply or a way out, the trail crosses several roads with access to town. The closest approach to downtown Prescott is around mile 25-30, depending on your starting point. Uber and Lyft operate in Prescott if you need a ride to a trailhead or back to town in an emergency.
