    Route Description for Pratt Lake Trail

    The hike to Pratt Lake is a wonderful breath of fresh air, with streams, lakes, and mountains peeking through the vibrant forest. This trail is a more direct out-and-back route to the lake, although there are many variations possible to enjoy this trail. If the full length is too much, you can shorten your trip, or keep going if you’re backpacking.

    The hike begins from the Granite Mountain Trailhead. Take Pratt Lake Trail #1007 north, crossing the stream and then curving back to cross it again, then two more. This is a common theme: there are lots of water crossings on this hike!

    After a wide left turn, you’ll traverse west, gaining elevation and crossing countless streams and creeks. The trail curves north again around the foot of the mountain beside you, and you should be able to see Talapus Lake below on your left.

    Wrap around the north end of Olallie Lake, switchbacking to lose a bit of elevation into the valley that Pratt Lake sits in. Even more creek crossings bring you around the eastern shore of the lake, which is deep blue and surrounded by green forest.

    You can either turn back here, settle in at the camp, or keep going on Pratt River Trail or Melakwa Lake Trail.
