The trail leading to the Sulphur Works begins along Highway 89 a short distance north of the southwestern entrance. The trailhead is shared by the Sulphur Works and Ridge Lakes Trails. Begin hiking from the northern side of the parking area. As soon as you get out of your car you'll smell the sulfurous gasses in the air. Follow the wooden stairs and boardwalk up to the fumaroles and hot springs of the site. An interpretive brochure is available in the parking area. It describes the hydrothermal features as well as their development. The total mileage for this trip is less than a half mile, so it is ideal for families that include young and old.
