Marmot Lake

Prepare for a challenging hike to two stunning alpine lakes on the Marmot Lake and Jade Lake via Deception Pass Trail. This difficult route covers 10.3 miles (16.5 km) with a significant elevation gain of 3111 feet (948 metres), typically taking around 5 hours and 24 minutes to complete. You will trek through diverse terrain, from dense forests and open meadows to stream crossings, before reaching the vibrant, milky turquoise waters of Jade Lake. The journey also brings you past the clear blue Marmot Lake and offers expansive views from Deception Pass, showcasing impressive peaks like Mount Daniel in the distance.

Before you head out, remember that a Northwest Forest Pass is necessary for parking at the trailhead. You will also need to fill out a free self-issue permit at the trailhead for safety and record-keeping purposes. Be aware that the access road can be rugged and potholed, sometimes requiring a shallow river crossing, so a high-clearance vehicle is often recommended. The best time to hike this trail is usually from May through September, ideally after the snow has melted, as patches can linger at higher elevations.

This trail is a popular choice for experienced hikers and backpackers seeking the unique beauty of the Alpine Lakes Wilderness. The iconic Jade Lake, with its distinct glacial hue, is a major draw, offering a truly memorable visual reward after the strenuous climb. The route provides a deep immersion into the natural environment, allowing you to experience the rugged charm and expansive vistas that define this part of the Cascade Mountains.
