Marten Lake Trail

Marten Lake Trail is a lightly trafficked out-and-back trail in Mount Baker-Snoqualmie National Forest that is rated as hard. This hike is very pretty but sees fewer visitors than other nearby trails, making it a good choice for a bit of solitude. There is excellent camping near the lake and you can swim if you wish to.
While the trail is fairly easy to follow, offline GPS mitigates the risk of losing your way at unsigned junctions.

Route Description for Marten Lake Trail
Marten Lake provides a lovely payoff for a reasonable amount of effort and offers a less busy experience than many other hikes in the area. Finding the trailhead can be a bit challenging so we recommend referring to your GPS track, but there are several trails that converge, making the risk of going the wrong way minimal.
The first 4.8 km or so from the trailhead are mostly level and straightforward. In areas where the trail is less obvious, look for flagging tape. Around 6.4 km, the trail becomes very rooty, so watch your step.
Upon reaching the lake, you can find a nice lounging spot or go for a swim. When you’re ready to return, take the same route, keeping an eye on your GPS to stay on the right path.
