The park has a great variety of trails, between relatively flat and easy meadow paths to switchbacks up Bergen Peak through the forest. The trails also drain quite well and tend to not be too muddy after rain. The parking lot usually fills up by around 10 in the morning so arrive early!

Mestaa'Ėhehe Pass (formerally Squ*w Pass) Summit is located at just over 9,800 feet. This is a popular area for cyclists in the summer time as the temperatures are significantly cooler than in Denver. This also marks the spot where most typically finish the bulk of their climbing. If you are heading back to Idaho Springs or Denver, it's mostly downhill with some great descending.

This segment of the trail offers a gradual climb and can be a great place for spotting elk grazing in the fields! Most of the meadow areas of the park are pretty exposed and get hot, so bring plenty of water!
