From either Idaho Springs (Exit 240 on I-70) or Bergen Park, (Exit #252 to Evergreen Parkway from westbound I-70, then turn west onto the Squaw Pass Road), drive to Echo Lake on HWY 103 (aka: Squaw Pass Road in Bergen Park), then take the Mt. Evans Road (entrance fee required) and drive to Summit Lake where you can park. When driven from Bergen Park, this road does a lot of winding around and receives a lot of bicycle traffic in the summer, especially on weekends. A nice bike lane has been added to the older, more narrow portion of the road that has helped to alleviate some of the dangers posed by such a multiple use road.
Designated National Forest campground at Echo Lake. Fee required.
