You can camp anywhere beyond a three-mile radius from the Rattlesnake's main trailhead, known as the "South Zone" (off Sawmill Gulch Road just west of Rattlesnake Drive). But remember: No motorized vehicles are allowed, and bicycles are prohibited within the wilderness boundary.
Rest assured that, despite its name, there have been no verified sightings of rattlesnakes in this area. You will, however, find ample opportunities to view many other wildlife species, including beaver, deer, elk, mountain goats and black bear. During spring and fall, you can see more than 40 bird species.
