Scuba diving in Hot Rocks
The Hot Rocks dive site is located in the waters around the volcanic Sangeang Island. The volcano is active, and due to this, streams of bubbles of volcanic gases rise from the sea bottom, creating a unique underwater picture. The shallow areas of the site contain rocks that are actually physically hot, and are unforgettable because they are covered with glowing pink anemones spreading neon light contrasting with the black sand. The deep areas of the site have sandy slopes and corals, black coral formations, and a small cave. Due to its unique seascape and unusual streams of volcanic gas bubbles, the site perfectly suits underwater photography lovers.
