Trappers Lake, elevation 9,633 feet (2,936 m),[1] is a lake in the Flat Tops Wilderness Area, which is in the White River National Forest in Colorado, United States.

The lake is roughly a mile and a half (2.4 km) long and half a mile (800 m) wide reaching depths of 180 feet (55 m).

It is surrounded by the Flat Tops Mountains, the most striking of which is the large semicircular Amphitheater which has a height of 1,650 ft (503m).

About 17,000 acres (6,900 ha) of forest surrounding the lake were burned by the Big Fish wildfire, started by lightning, in July 2002.

[3] The area around the lake was put largely off limits to development in 1920, due to the recommendation of Arthur Carhart, hired by the Forest Service to make a survey for a road around the lake.
