Watson Lake Loop

The Watson Lake Loop is the hike people picture when they think of the Granite Dells: a route that climbs over, around, and between giant granite boulders, with Watson Lake shimmering below. It’s the most scenic hike in Prescott, and also one of the most demanding for its length, because much of it is a scramble across bare rock. This is our guide to hiking the loop, including how to follow the route, where to park, and how to tell whether it’s right for your group.

What to expect on the trail

The loop is about 5 miles, though measurements range from roughly 4.5 to 5.3 miles depending on the exact route. Don’t let the distance fool you: the City of Prescott rates segments of it “special/technical,” and the Highlands Center’s trail map calls it strenuous. Large parts cross bare granite, where the route is marked with white dots painted on the rock. Follow them closely, because the Dells are full of unsigned side trails, and it’s easy to wander off route. The Over-the-Hill section has short, steep climbs and descents that call for hands-on scrambling in places.

The loop is a chain of named segments, including the Lakeshore, Over-the-Hill, Northshore, Flume, and Watson Dam trails, and it finishes on the flat Peavine Trail along the lake’s east shore. Along the way you cross Watson Dam on a narrow metal bridge over Granite Creek, a highlight in itself. There’s almost no shade. We’d call this one hard, and it’s not a good choice for young kids or anyone uneasy on steep rock. Mountain bikers use parts of the network too, though Over-the-Hill is hikers only.

Highlights

• The Dells up close. The Highlands Center’s map describes the loop as a “world-class scenic trail,” and it’s hard to argue: you’re walking on top of the formations, not just past them.
• Lake views the whole way. Watson Lake was created in 1916 by damming Granite Creek, and the water winds between the boulders like a maze.
• Birding. The lake is part of an Audubon Important Bird Area. Look for herons, cormorants, ducks, and raptors.
• Water fun after the hike. The park offers fishing (bass, catfish, crappie, and carp), kayak rentals, and two boat launches. Swimming is not allowed.

Getting there, parking, and fees

Start at Watson Lake Park, 3101 Watson Lake Park Road. From Highway 89 heading north, take the first right at the roundabout into the park. It’s a City of Prescott fee site: $5 per vehicle per day, free on Wednesdays, with multi-visit and annual passes available from the city. Hours are 6 a.m. to 10 p.m. from April through October and 7 a.m. to 6 p.m. from November through March. You can also join the loop from the Peavine Trailhead on Sundog Ranch Road.

The park has restrooms, picnic tables, ramadas, grills, a playground, a disc golf course, and summer camping, which makes it an easy base for a family day even if not everyone hikes the full loop.

Insider Tip: Wear shoes with sticky rubber soles and carry more water than you think you need. The granite reflects heat, and there’s nowhere to refill once you leave the park. If you want the scenery without the scramble, walk the flat Peavine along the east shore instead.

When to go

Spring and fall are best. Summer afternoons on the exposed granite are hot, and monsoon storms bring lightning that you don’t want to be caught in on top of the rocks, so go early. In winter, avoid the loop when the rock is wet or icy; the granite gets slick fast.

Make a day of it

Rent a kayak and see the Dells from the water, or pair the loop with nearby Willow Lake. Our Prescott lakes guide covers all four lakes, and the Trail Finder can help you find something gentler for the next day.
