About
Big Trinity Cabin offers a quiet retreat in the high alpine landscape of Boise National Forest's Trinity Recreation Area. Situated in a dense lodgepole pine forest near the East Fork Roaring River, the cabin is nestled 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 cabin accommodates six guests with one double bed and a sofa bed. It is equipped with a wood stove for heating and cooking, along with cookware, dishes, a dining table, and chairs. Guests must bring their own bedding, lighting, and emergency supplies. Drinking water is available from a hand pump outside, and an outhouse with vault toilet is provided. There is no electricity or propane, and phone service is approximately one hour away. The 4-mile Rainbow Basin Trail system for pedestrian use offers access to several alpine lakes from the nearby Big Trinity Lake Campground trailhead. Anglers can fish for rainbow and cutthroat trout, and the lakes are ideal for canoe or kayak exploration. The summit of Trinity Mountain is the highest drivable point in Idaho, offering panoramic views from the lookout tower.
