Jade Lake via Deception Pass Trail and Marmot Lake Trail(edit)

Overview

Enjoy this out-and-back trail near Roslyn, Washington, known for its challenging terrain. This popular area attracts backpackers, campers, and hikers, so expect to encounter others along the way. The best time to visit is from May through September. Dogs are allowed but must be kept on a leash.

This gorgeous, strenuous hike may involve off-trail sections, steep climbs, and multiple river crossings. Along the route, you’ll find stunning alpine lakes, beautiful views, and excellent camping spots. Be prepared to get your feet wet and navigate snow patches—even in summer. Melting snow can create hidden hazards, so use caution. The trail can be difficult to follow at times, especially when approaching Jade Lake. This is a delicate alpine environment—please practice Leave No Trace principles.

There are two main ways to reach Marmot Lake: via this route from Tucquala Meadows Trailhead, or from Deception Pass Trailhead. From Tucquala Meadows, follow the Deception Pass Trail past Hyas Lake to Deception Pass, then continue on the Marmot Lake Trail. Camping is available at Marmot Lake.

Beyond Marmot, the route to Jade Lake becomes more challenging. The first cairn pile is not the correct route—you must continue to the far end of the lake to find the right cairns. Follow them to cross a small waterfall and ascend from there.

The access road to the trailhead is rugged, with potholes and a small river crossing. Use GPS and follow the mapped route closely. If hiking in snow, bring chalk and flagger tape to mark your path, and have a backup plan if you can’t find a snow-free camping spot.

A Northwest Forest Pass is required for parking.
