Explore Carlsbad Cavern at your own pace with these two self-guided trails. Access requires an entrance ticket.
Big Room Self-Guided Trail
The most popular route, the Big Room, is the largest single cave chamber by volume in North America. This 1.25 mile (2 km) trail is relatively flat, and will take about 1.5 hours (on average) to walk it. Actor and comedian Will Rogers called the cavern, "The Grand Canyon with a roof over it." You will be rewarded with spectacular views, cave formations of all shapes and sizes, and a rope ladder used by explorers in 1924.
Natural Entrance Self-Guided Trail
The 1.25 mile (2 km) Natural Entrance Trail is extremely steep. Depending on if you decide to hike up or down, you gain or lose about 750 feet (229 m)—equivalent to walking up or down a 75-story building. The hike takes about one hour (on average) to complete. This trail is not recommended for visitors with heart or respiratory conditions.
