Spray Park–Ipsut Pass Loop

Spray Park–Ipsut Pass Loop is a 16-mile circuit from Mowich Lake through the open meadows of Spray Park and Seattle Park, down to the Carbon River and Ipsut Creek, then over Ipsut Pass to return. It gains about 5,100 feet and reaches 6,375 feet. Budget 10 to 14 hours; about 12 is a realistic full-day plan with breaks. This is a hard route for its distance, repeated climbing and uneven river corridor. If you want the main meadow and waterfall without the river miles and pass climb, the separate 6-mile Spray Park hike is an out-and-back.

From the walk-in campground, follow a short stretch of Wonderland Trail south, then turn onto Spray Park Trail. The first mile trends gently downhill around Eagle Cliff and Eagle’s Roost. A short side spur leads to Spray Falls, where water breaks into a series of cascades below a high cliff; leave time to visit, then return to the loop. From there, switchbacks climb about 600 feet in half a mile. The grade is abrupt after the easy opening, and the steep switchbacks demand careful footing.

The climb opens into Spray Park’s broad subalpine meadows, with Echo Rock, Observation Rock and Russell Glacier above the flowers; clear days can bring the North Cascades into view to the north. The route reaches its high point here, around 6,375 feet, then drops about three miles through Seattle Park toward Cataract Valley and the Carbon River. You pass open patches, small tarns and forest edges rather than staying in one meadow the whole way. Keep to the built tread: the plants here grow slowly, and a bootstep off trail can leave damage long after the flowers fade. For a photo, let the path lead through the meadow toward the surrounding peaks instead of trampling a closer foreground.

At Cataract Valley, the route descends to the Carbon River junction and follows the Wonderland Trail north and northwest. This is a rougher, more remote stretch, with uneven riverbed sections, wet rock and stream crossings; bridges and log crossings call for careful footing. At Ipsut Creek, pass the campground spur and continue by Ipsut Falls. The trail then climbs about 2,500 feet over three forested miles to Ipsut Pass. After the long ascent, the route eases along Castle Peak’s flank before its final downhill mile back to Mowich Lake. The pass climb is the main test: save energy for it rather than treating the river section as the finish.

Mowich Lake sits in a glacial basin and is the park’s largest and deepest lake. The campground is walk-in, with pit toilets; food service and potable water were not found on this circuit. Carry your day’s food and a way to treat stream water. The road is unpaved and can be rough beyond its first few miles, and the Mowich area is usually accessible only from mid-July to mid-October. Dogs are prohibited on park trails. A wilderness permit is required if you camp overnight at Eagle’s Roost, Cataract Valley, Carbon River or Ipsut Creek.
