Willow Lake Loop: The Quiet Half of the Granite Dells
A 5.4-mile loop around Willow Lake with 431 feet of climb, the same granite as Watson Lake with a fraction of the people, and a shoreline that moves with the water level.
September 6, 2026 · The Owners
Watson Lake gets the photographs. Willow Lake, immediately north of it, has the same granite, a longer loop around it and a fraction of the people. If you have seen the Dells on a postcard and arrived to find the car park full, this is where to go instead.

The section that catches people out
The south and east sides are an ordinary lakeside path. The north and west sides are different: the route crosses open granite where there is no worn tread to follow, and the way is marked with cairns and paint blobs on the rock. In good light it is obvious. In flat light, or when you are talking rather than looking, it is very easy to walk off the line and end up scrambling.
Nothing here is dangerous and the lake is always on one side of you, so the correction is short. But budget for it, and do not assume 5.4 miles of lake loop means 5.4 miles of path.
The water level moves
Willow is shallow, and its level swings hard between a wet spring and a dry autumn. In low years the water retreats a long way from the shoreline drawn on the map, and stretches of the loop cross flats that are lake bed for part of the year. That is normal. It does mean the walk looks quite different depending on when you come, and that photographs from a wet April are not what you will find in October.
Swimming is prohibited, here and at all the other lakes, which is the single fact most visitors get wrong about Prescott. The full comparison of the five is in Prescott’s five lakes, and the direct Watson-versus-Willow question is settled in Watson or Willow.
When to go
Spring and autumn are best. Summer afternoons on open granite are punishing and there is very little shade anywhere on the loop. Winter is fine and often empty.
The $5 city fee covers Watson, Goldwater, the Peavine and the Constellation Trails on the same day, so a single Wednesday, when it is free anyway, can take in several. Everything you might pay for in the area is listed in what a Prescott trip costs.
Common questions
How long is the Willow Lake loop?
5.4 miles around with 431 feet of elevation gain. Allow two to two and a half hours walking. It is longer than the Watson Lake loop next door and considerably quieter.
Can you swim in Willow Lake?
No. Swimming is prohibited at Willow Lake, as it is at Watson, Goldwater and Lynx. All of them are reservoirs and recreation lakes rather than swimming holes. You can paddle and fish.
Is the Willow Lake trail well marked?
Mostly. The north and west sides run over open granite where the route is marked with cairns and paint rather than a worn path, and that section catches people out. The south and east sides are obvious.
Does Willow Lake dry up?
The level swings a lot. Willow is shallow and in dry years the water pulls back a long way from the marked shoreline, which leaves parts of the loop walking across flats that are underwater in a wet spring. It is not a fault in the trail, it is the lake.
What does it cost to park at Willow Lake?
$5 per vehicle at the City of Prescott lakes, free on Wednesdays. The same pass covers Watson Lake, Goldwater Lake, the Peavine Trail and the Constellation Trails.
