Natural Features
The cabin is located in a dense lodgepole pine forest close to the East Fork Roaring River at an elevation of 7,900 feet. It's 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 9,451 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 black bear.Nearby Attractions
The summit of Trinity Mountain is the highest drivable point in Idaho, although the road may be blocked by snow until early July. A short, steep hike takes visitors to the lookout tower for panoramic views of several subalpine lakes and other mountains in the Boise Range.The facts
