Monarch Lake Trailhead provides parking for approximately 40 vehicles and serves as the primary access point for the 4-mile Monarch Lake Loop trail and Indian Peaks Wilderness backcountry routes.

A day-use fee ($5 per vehicle) is required and can be purchased at the Arapaho Bay Pay Station or online; the final mile of road to the trailhead is closed November 15 to June 15, requiring winter hikers to snowshoe or cross-country ski in.

Facilities include restrooms and a wilderness information cabin, with leashed dogs permitted on all trails.
