Tunnels Beach is best described as a high-value natural snorkeling site rather than a serviced recreational beach. It is internationally known for its extensive coral reef system and underwater lava formations, which create cave-like structures often referred to as “tunnels”.
The shoreline is wide and scenic, backed by steep green mountains, including Mount Makana (Bali Hai). The beach is undeveloped and remains largely in a natural state.
Visitors are advised to plan their visits due to limited facilities, parking constraints, and changing ocean conditions.
