Hiking Lower Tuscohatchie Lake

Lower Tuscohatchie Lake is accessible from multiple different trailheads, offering hikers multiple hiking options. One option is to start from the Granite Mountain/Pratt Lake trailhead. 

Start by heading up the Granite Mountain Trail until it connects up with the Pratt Lake Trail. From there, you will follow the trail until you reach Pratt Lake.

On the way, a short detour will lead you to Olallie Lake. However, the way back up from Olallie Lake is a steep boot trail to connect back with the Pratt Lake Trail. It steadily climbs in elevation as you go up, never getting that steep.

Expect to encounter quite a few river and creek crossings on the Pratt Lake Trail. Once you reach a ridge, you'll head into the Pratt Lake Basin, hiking down the surrounding boulder fields. There is camping at Pratt Lake. From Pratt Lake, you will connect with the Melakwa Lake trail and hike along the side of a mountain with amazing valley views. Even in August, you may find mud here.

Lower Tuscohatchie has quite a few established campsites with a few of them being shorefront. 

There are plenty of water crossings and there is water at the lakes. Having extra water in this area won't be needed as long as you have a filter. In late summer, as creeks and rivers can dry up, having an extra liter of water is advised.

WTA Pro Tip: Save a copy of our directions before you leave! App-based driving directions aren't always accurate and data connections may be unreliable as you drive to the trailhead.

Getting There

From Seattle, head east on I-90 to exit 47. Turn left and drive over the freeway, then turn left at the T. Proceed to the nearby Pratt Lake-Granite Mountain parking area. Be aware that this parking area gets very full with people parking on both sides of the road, and sometimes leaving is harder than finding a spot. A Northwest Forest Pass and self-issued Alpine Lakes Wilderness Permit are required; both are available at the trailhead.
