There are many entry points into Indian Heaven and this is just one of them from the Thomas Lake Trailhead, located on the west side of the Wilderness. It is also one of the easiest hikes into the interior. You must have a Northwest Forest Pass to park here due to the well maintained pit toilet facility at the parking lot. Fill out a wilderness permit at the trailhead. This is one of our favorite fall hikes as the huckleberry bushes will have turned a beautiful red color and the mosquitoes are few and far between. This track description is from the Thomas Lake Trailhead to Junction Lake and back. The elevation is fairly mild and you may find yourself stopping frequently to take snapshots of all the lakes on both sides of the trail. When you reach Blue Lake on your right (it's mighty blue), turn left onto the Pacific Crest Trail. The trail will mosey along, then go uphill, and then downhill to Junction Lake.
