Lower Dewey Lake sits in the Dewey Lakes Trail System, a set of trails that starts very close to Skagway's Historic District. The trails lead up into spruce and hemlock forest, and the lakes are the main reason people climb. Skagway grew as a saltwater port during the Klondike Gold Rush, and these hills have been used for walking ever since.

A visit starts with a walk north along the railroad tracks from the depot, so watch for trains at the crossing. Once on the trail, take the sharp right at the junction to reach the lake. The loop runs about 3.6 miles, with a rougher stretch on the east side. From the hillside you can turn around and see the peaks that enclose the town.

• Beware of trains when crossing the railroad tracks to the trailhead.
• At the junction take the sharp right to reach the lake, since going straight leads to a reservoir.
• The climb is about 500 feet of elevation gain over the loop.
