Overview

Less than an hour from Seattle, the Pratt Lake Trailhead takes hikers to the shores of the Pratt Lake Basin, surrounded by alpine peaks, forests and talus slopes. The strenuous hike is undoubtedly worth the effort, and day-hikers will wish they brought their tent. Find a good spot for a swim, and enjoy a beautiful retreat to the Alpine Lakes Wilderness.

This is a difficult one way trail in Mount Baker-Snoqualmie National Forest.

This trail goes by Olallie Lake and Pratt Lake.

Getting Started

The drive to the Pratt Lake Trailhead from Seattle is straightforward, just up I-90 east of Seattle approximately 50 minutes, traffic permitting. The trailhead begins on the same trail as that leading to Granite Mountain, but soon hits a junction. Veer left for Pratt Lake.

To break up the hike, Olallie Lake offers first-come first-serve camping on its glistening shore, and great swimming opportunities.

For those looking to put in more miles, there are plenty of lakes in the vicinity if you don't mind putting in a few more miles. Check out Talapus, Island and Rainbow lakes, or the Lower Tuscohatchie Lake just past Pratt Lake on the trail that leads to Melakwa Lake and around to Denny Creek.

Make sure to display your Northwest Forest Pass in the parking lot.

    Great hike to a gorgeous alpine lake. Trail was easy to follow and mostly in the shade. Crossing the exposed rocks right before the lake was the most challenging part. Beautiful backcountry

Moderate steady uphill through nice forests and over pretty creeks for 4.5 miles and 2300 feet, then down 1.5 miles 750 feet to the camps at the far end of the lake. The trail guides call it 5.5 miles but it appears to be a little over 6. Solo with my little dog Mazzy. We have the entire place to ourselves. Saw two people before the Granite Mountain cut off and not a soul since. Started at 6:45om and pushed about as fast as I could manage for being out of shape to make it to camp before dark, and we made it!

Our 3rd attempt at getting to Pratt. The 1st try... we ran out of time. 2nd try, snow & ice cover was too dangerous (according to the Rangers), so we've ended up going to Talapus instead. Made it this time. Great hike, and great running trail on the way down.
