Santa Ana is a big name in game-fishing circles, with Babuyan Strait rich in marlin, dorado and sailfish. The fishing season is between March and June, and you can arrange sports-fishing trips through the Philippine Game Fishing Association.

Between February and May the Babuyan Strait is also a good place to go whale-watching; look for all manner of cetaceans, from humpback, pilot and pygmy killer whales to spotted dolphins and bottle-nosed dolphins.
