What to See and Do
Hiking and Biking
Owl Canyon Trail
This is not a well-traveled trail, so you'll enjoy some solitude. If you're a birder, then bring your binoculars.
3.3 miles

Rainbow Basin Slot Canyon
Unlike many trails in national and state parks, not to mention BLM areas, dogs may be off-the-leash in some areas along this trail. It, too, offers solitude.
1.3 miles

Rainbow Basin Loop
This is the most popular trail within the Rainbow Basin Natural Area. Like the Owl Canyon Trail, it provides exceptional opportunities for birding.
7.5 miles
Moderate
Rainbow Basin Dry Falls
The desert wildflowers along this trail are its chief feature. Despite this trail's difficulty, it's a good choice for families with children due to the short distance.
1.8 miles

Fishing and Boating
The closest place to fish, boat, or swim is Silverwood Lake, which is a little more than 50 miles from the Rainbow Basin Natural Area. There are forested hiking trails near the lake, and you can fish, boat, and swim in the applicable designated areas. A further 1.5 miles on, there is the recreation area associated with Silverwood Lake. The Pacific Crest Trail passes through this area, and you can hike a short section of it if you wish.
Climbing
Sawtooth Canyon and its surrounding area lie about 20 or so miles south of the Rainbow Basin Natural Area. The climbing there is tough and is rated 5.9 up to 5.12 sport climbs. Many of the crags aren't very high, but they're quite technical. The toughest route is called Double Kneebar Ranch, and it's a 5.12c, making it only for well-trained and experienced climbers. Jug Haul, at 5.9, is the easiest climb in the area.
Wildlife Viewing
In addition to the aforementioned desert tortoise and birds, pronghorn, mule deer, and various lizards make their home in the Rainbow Basin Natural Area. The pronghorn is especially notable as the fastest land animal in the Western Hemisphere. It can run nearly 60 miles an hour. The best times to see the area's wildlife are in the very early morning and at dusk.
Picnicking
There are no picnic areas outside of the campground itself. Each of the 22 BLM campsites has a picnic table and a fire ring.
