The Trailer Lakes are a series of three small alpine glacial lakes in Boise County, Idaho, United States, located in the Sawtooth Mountains in the Sawtooth National Recreation Area. The Trailer Lakes are in the Trail Creek watershed, which is a tributary of the South Fork Payette River. The lakes are most easily accessed from Sawtooth National Forest trail 453.[1]
The Trailer Lakes are in the Sawtooth Wilderness, and a wilderness permit can be obtained at a registration box at trailheads or wilderness boundaries. Regan Lake is downstream of the Trailer Lakes, and Mount Regan at 10190feet is to the southeast of the lakes.
