Big Trinity Lake Campground is within the beautiful Trinity Recreation Area. There are17 campsites on Big Trinity Lake and there are more sites near the beautiful smaller lakes in Rainbow Basin.
The campgrounds in the Trinity Recreation area offer a quiet retreat in a beautiful high alpine landscape. The sites are situated within a popular summer recreation area with many activities to enjoy.
There is a limited season due to late snow melt, but they are accessible by car.
The campgrounds are located in a dense lodgepole pine forest close to the East Fork Roaring River at an elevation of 7,900 feet. 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 black bear.
Hikers can access the 4-mile Rainbow Basin Trail System from Big Trinity Lake. The William H. Pogue National Recreation Trail and Lava Mountain Trail are for off-road vehicle enthusiasts, mountain bikers, hikers and horseback riders. Both of these trails can be accessed near Big Roaring River Lake. The Little Roaring River Trail at Little Roaring River Lake is also open to mountain bike, off-road vehicles and hiking.

Anglers can fish in any of the nearby lakes for rainbow and cutthroat trout. The lakes are also ideal for exploring by canoe or kayak.
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.
