Petroleum and Anderson Lakes Trail is a 3.9 mile moderately trafficked out and back trail located near Aspen, CO that features beautiful wild flowers and is rated as moderate. The trail offers a number of activity options and is accessible from May until September.
Directions from Aspen: Drive ten miles east of Aspen on Highway 82 to Lincoln Creek Road. Turn right and drive 6 1/2 miles on Lincoln Creek Road to Portal Campground. From Portal Campground the road becomes very rough and a high clearance four-wheel drive is required. Either drive or hike the remaining 3 1/3 miles to a fork in the road. Take the right fork, cross the creek and park on the other side. Camping near the lakes is not recommended because of limited campsites and the fragile alpine vegetation. There is good fishing at both lakes.
Easy hike to gorgeous lakes. There is a smaller unnamed lake on the way from Anderson to Petroleum. Alpine flowers carpet the tundra. Long 1 1/2 hour trip from downtown Aspen, but worth every minute.
One of the most amazing hikes ever! 4x4 trip up is great followed by an amazing hike up to the most beautiful lake and vistas. A must!
