East Portal Trailhead offers a large parking area and serves as the primary access point to South Boulder Creek Trail and multiple wilderness routes including the Continental Divide Trail in the James Peak Wilderness.

The trailhead provides restrooms and accommodates both hikers and horseback riders, with year-round campfire restrictions and campsites required to be at least 100 feet from water and trails.

Located near the historic Moffat Tunnel in Gilpin County, this is a highly trafficked recreation hub for day hikes and backpacking adventures.
