Welcome to Oecusse
With marine biodiversity similar to Ataúro (bring your own snorkels and diving equipment) and easy access from Dili, Oecusse is a place worth spending a few days in.
Pantemakassar, aka Oecusse Town, has a palm-fringed foreshore that provides great sunsets. November sees pilot whales swimming by, and divers are likely to spot a turtle or two underwater each time they hit the water. The coral cover here is very good; enlist someone to watch for crocodiles and you can snorkel out from in front of the beachfront church.
Oecusse's seagrass meadows are home to dugongs. The best beach begins 2km east of town on Pantai Mahata, which ends at a stunning red-rock headland.
