Access Boston Run Trail in the far corner of the main parking lot for Happy Days Lodge. This 3.1-mile loop trail explores Boston Run, one of many headwater streams that flow into the Cuyahoga River. The stream comes in and out of view as the trail winds along serene ravines and ridges.

Along the way, notice how the surrounding forest shades the stream. Cool water temperatures allow pollution-sensitive salamanders and the tiny insects they eat to survive. The roots of the oak, maple, beech, and tulip trees hold soil in place and soak up excess water, reducing downstream flooding.
