The hike to the Caldwell Lakes is on a trail upgraded since 2010. It passes through thin and thick forests with a variety of wildflowers. Views of Mt Shasta open up as you reach the lakes. A good option to avoid the crowds at Heart Lake.
The Caldwell Lakes Trailhead is on a very short forest road (41N74) that branches off FR17 just before it crosses Parks Creek (See detailed driving directions below) The trailhead Kiosk is 120 feet up the dirt road from FR17. The first mile or so of the trail was reconstructed since 2010, it is now a nice trail instead of the washed out road that it used to be. The trail passes through a thin forest and goes along babbling brooks before ascending through a thicker forest to Lower Caldwell Lake.
Above Lower Caldwell Lake the trail climbs up onto an open slope before reaching Upper Caldwell Lake, which is ringed with wildflower meadows. Upper Caldwell Lake might be considered two lakes connected by a very short stream. Don’t miss the view from the outlet stream of Mt. Shasta.
