The Boulder Brook passes through upper-montane and low subalpine terrain. Solitude seekers will enjoy its lively waters, deep-green streamside, diverse riparian vegetation, terrific autumn foliage and good views of the Continental Divide and Mummy Range.

Looking out at the Continental Divide from the beginning of the trail.

The trail follows the Boulder Brook virtually the entire way up.

Great view of Longs Peak near the top of the trail.

Some beautiful falls along the Boulder Brook trail.

A browned out, twisted tree lying along the side of the trail.
