Hagukan Cave is a partially submerged cavern located in the Visayas region of the Philippines. The site is named for the snoring sound produced as waves enter its narrow opening. Inside, the water exhibits a luminescent blue-green hue when disturbed. Snorkellers should note the presence of water stratification, where a colder, hazier top layer sits above a warmer, clearer bottom layer. Access to this site requires a boat, and it is rated as an intermediate location due to the overhead environment and potential for surf, sharp coral, and strong currents. Guided tours are available for those exploring this unique marine cave system.
