About
Big Trinity Cabin offers a quiet high-alpine retreat at 7,900 feet elevation within the popular Trinity Recreation Area. The cabin sleeps six and is equipped with one double bed, a sofa bed, drop-down kitchen table, chairs, dining table, dishes, cookware, and a wood stove for heating and cooking. Outside amenities include a picnic table and campfire ring with grill. The cabin is stocked with seasoned firewood and splitting tools. Nestled in a dense lodgepole pine forest near the East Fork Roaring River, the cabin sits among four subalpine lakes: Big Roaring River Lake, Little Roaring River Lake, Big Trinity Lake, and Little Trinity Lake. Trinity Mountain, the tallest peak in the Boise Range at 9,451 feet, rises just to the south. The area comes alive with summer wildflowers after snowmelt and is prime habitat for elk, deer, and occasional black bears. The 4-mile Rainbow Basin Trail System provides pedestrian access to several lakes from the nearby Big Trinity Lake Campground trailhead. Motorized trails include Roaring River Trail 045 and Lava Mountain Trail 125. Anglers can fish the nearby lakes for rainbow and cutthroat trout, and the lakes are ideal for canoeing or kayaking. Trinity Mountain summit, Idaho's highest drivable point, offers panoramic views from the lookout tower.
