The Trail follows an old jeep road that is now closed to motorized
vehicles. The trail follows Anderson Creek passing through fir
forests then tundra. In about one mile the trail forks. Take the left
fork to reach Anderson Lake in another 1/4 mile. Take the right
fork to reach Petroleum Lake in another 3/4 mile. Stay on the steep
trail to the right of the outlet stream of Petroleum Lake to reach the
lake. The waters of Anderson Lake are a beautiful turquoise blue
while Petroleum Lake's are dark giving the lake it's name.
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.
May through September
(NOTE: Snow may obstruct the trail during the Early Summer months.)
