Trail Overview

This charming boardwalk trail runs along the shores of Coldwater Lake—the direct result of Mount St. Helens' 1980 eruption, which dammed Coldwater Creek and carved out the lake in its path. Interpretive displays along the route vividly recount that transformation, guiding hikers through both geologic history and ecological resurgence.

Along the path, you might spot intriguing features like beaver-chewed trees, small trout splashing on the water's surface, and marshy wildlife activity to observe and enjoy.

A floating deck or footbridge offers serene lake views—especially magical on calm, sunny days when the surrounding hills reflect perfectly in the water.
