Dauin (dow-in) is a small coastal town on the Bohol Sea, but diving has put it on the international traveller's radar. It's known for macro diving in the Masaplod Norte marine reserve, and as a base for trips to nearby Apo Island, as well as for good snorkelling over the drop-off about 20m from shore. The beach itself, generated partly by volcanic ash, is not attractive, so you'll probably stick to resort pools. Most resorts – and the number is expanding – offer local excursions, such as popular Twin Lakes and Lake Balanan trips. The sulphur Baslay hot springs are nearby too.
Nearby Malatapay (9km south), the departure point for Apo Island, has a huge and lively market where every Wednesday morning villagers, fishers and Bukidnon tribespeople can be found loudly bartering goods and feasting on lechón (spit-roasted whole pig).
