The Wild Basin Trailhead is on the east side of the Continental Divide between Meeker Park and
Allenspark. Turn west on to Wild Basin Road from Colorado Highway 7, at a junction about 13 miles
south of Estes Park. Continue west to the Copeland Lake area, roughly one-half mile from Highway 7.
The Wild Basin trailhead is about 2 miles beyond Copeland Lake on a narrow gravel road. The trailhead
begins on the south end of the parking area at the Wild Basin Ranger Station. Access to this parking
area may be limited during seasons when snowfall is still present.

The Thunder Lake Trail leads past Copeland Falls, Calypso Cascades, and Ouzel Falls before reaching a
junction with a trail to Bluebird Lake. Continue toward Thunder Lake, crossing North Saint Vrain Creek, and
eventually reaching another junction. At this second major junction, with the trail to Lion Lake #1, take the
left-hand trail and continue toward Thunder Lake. Note that there is an unmaintained trail for backpackers
that connects on both ends to the Thunder Lake trail. This trail runs from west of Copeland Falls to near the
North Saint Vrain campsite area. The Thunder Lake Trail is more well graded than this alternate trail.
