Route Description for Thompson Lake Trail
Thompson Lake is a serene, pretty lake amidst the mountains accessible on a longer, more demanding trail. If you’re searching for a decent workout without heavy crowds, this trail is a good pick. Keep in mind that you’ll drop a considerable amount of elevation to access the lake, so keep some gas in the tank to get back up onto the trail on your return trip.
The hike begins on the Granite Creek Trail. Much of the hike is on a somewhat narrow, rocky trail that can be a bit overgrown in spots. Where the logging road approaches the trail early on, stay left to stay on your route.
The hike continues, gaining elevation and curving towards Granite Creek. You’ll come to a T-junction where you should stay left. The Granite Creek Connector goes off to the right, and you’ll take the Granite Lakes Trail on the left.
The trail hugs, and then crosses the creek. Where the path forks, stay left again onto Thompson Point Trail. At about 1,210 m of elevation, take Thompson Lake Trail straight ahead as the Thompson Point Trail splits off to the left.
Climb, climb, climb, then drop off down towards the lake. The approach trail can be slick when wet, so be careful. You’ll have access to the lakeshore, and the trail continues halfway around the lake on the left if you want a different vantage point.
When you’re ready, retrace your steps, taking on a steep initial ascent before a more manageable descent back to the parking lot.
