After about a mile, the trail becomes steeper as it climbs the ridgeline. Near the lake, the forest opens into grassy meadows. The path can be rooty in parts and may have deep ruts, mud, and snow, especially outside the peak season.

During summer, the meadows are vibrant with wildflowers, and from the top of Summit Lake Peak, you can enjoy panoramic vistas.
