Campgrounds are located in a dense lodgepole pine forest close to the East Fork Roaring River at an elevation of 7,900 feet. They’re nestled among four subalpine lakes: Big Roaring River Lake, Little Roaring River Lake, Big Trinity Lake and Little Trinity Lake. The peaks of the Boise Mountains surround the cabins, and Trinity Mountain, the tallest in the range at 9,700 feet, is just to the south. Snow can make this area inaccessible until early July, but soon afterward, the land is blanketed by colorful summer wildflowers. This area is a haven for elk and deer, but wildlife watchers may also spot an occasional moose or black bear.
