Old Guano Trail

Within the day use area, you can begin this trail at the dirt road adjacent to the natural entrance to Carlsbad Cavern. It follows the historic road used to haul guano from the cavern in the early 1900s, and hikers will see ruins and debris from the mining operation about a mile (1.6 km) from the entrance. This trail runs 3.7 miles (6km) descending the escarpment, and ending at the Whites City campground. One-way travel takes an estimated two hours at an easy activity level with a 750 feet (216 m) change in elevation. It is closed near the cavern entrance during Bat Flight programs.
