About
Big Trinity Cabin offers a quiet retreat in a beautiful high alpine landscape within the Boise National Forest. The historic guard station is situated at 7,900 feet elevation in a dense lodgepole pine forest, nestled among four subalpine lakes: Big Trinity Lake, Little Trinity Lake, Big Roaring River Lake, and Little Roaring River Lake. Trinity Mountain, the tallest peak in the Boise Range at 9,451 feet, rises just to the south. The cabin sleeps six people and is equipped with one double bed, a sofa bed, a drop-down kitchen table, chairs, cookware, dishes, and cleaning supplies. A wood stove provides heating and cooking capabilities, with seasoned wood, a splitting maul, axe, and hatchet provided. Outside amenities include a picnic table, campfire ring with grill, and a vault toilet. Drinking water is available from a nearby hand pump. The area offers excellent recreation opportunities including fishing for rainbow and cutthroat trout in nearby lakes, hiking on the 4-mile Rainbow Basin Trail system, and wildlife watching for elk, deer, and occasional black bears. Motorized trails including Roaring River Trail 045 and Lava Mountain Trail 125 are also accessible. The summit of Trinity Mountain offers panoramic views from the lookout tower, accessible via the highest drivable point in Idaho. The cabin has no electricity or propane, and guests must pack out all trash and provide their own bedding and lighting.
