Romulo Island
Dive site
Romulo Island is a small uninhabited island off the Nasugbu coast whose sheer walls descend from 3 meters to beyond 40 meters on the exposed seaward face. Dense sea fan gardens and soft coral trees colonise the wall from 15 to 30 meters, and large Napoleon wrasse are permanent residents that regularly approach divers at close range. The channel between the island and the Nasugbu headland accelerates tidal flow and aggregates schooling bigeye trevally and barracuda, while the calmer lagoon side has shallower hard coral formations used as a safety stop habitat. This is the anchor site of Nasugbu diving and the most visited reef on the South China Sea side of Batangas.
