The Muskeg: A Carnivorous Garden“If you’re on a boardwalk over a wet, spongy landscape, you're in a muskeg. It’s a peat bog, sitting on land that's still springing back up after the glaciers retreated a couple hundred years ago.”

Trail guide
Begin on the Bartlett River Trail from the Bartlett Cove trailhead. After roughly 0.7–0.75 mile, follow the signed Bartlett Lake branch as it climbs the moraine and continues through spruce–hemlock forest, moss-covered boulders, wetlands, roots, mud, and small creek crossings to Bartlett Lake. The lake trail is less maintained than the shorter Bartlett Cove routes, so wayfinding and footing require attention.
Plan on a moderate full-day hike; the NPS trail guide estimates 7–8 hours. The main challenge is wet, uneven footing and route-finding rather than steep climbing. The route is slow after rain and deserves extra daylight and weather margin.
For shorter Bartlett Cove hikes or wetter-day alternatives, consider the Forest Loop, Bartlett River, or Tlingit trails. They share the same rainforest setting without the full-day commitment.
