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. Use this parking for Grey Wolf, Spalding, Warren and Rogers. 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.
For hiking to Epaulet/Epaulie and Rosalie, you can drive on up from Summit Lake, continuing on the Mt. Evans road for another 1.6 miles to a set of two switchbacks. From the first switchback, continue driving another .8 mile to the coordinates below where there's enough of a pullout on the south side of the road to park. If unable to park here, continue another few tenths of a mile to another switchback and park there where the road widens. Coordinates for the first pullout are N 39° 34' 46.00 W 105° 37' 54.00" 13,205 ft. elevation. If you can park here, it will save almost 2.5 miles of walking along the road or nearly 5 miles round-trip.
Designated National Forest campground at Echo Lake. Fee required.
