Pulau weh (or Weh Island) is one of the best snorkeling and diving destinations in Southeast Asia. You can get there by ferry from Banda Aceh, capital of Aceh. Banda Aceh can be reached from Medan by airplane, or by a 10-12 hours bus ride. On the northeastern leg is the port town of Sabang, where most of Weh’s population lives. The primary tourist beaches are Gapang and Iboih, which are about 20km away heading towards the northwestern leg. It’s always a little rainy on Weh, with two monsoon seasons. November to January are the wettest, coolest months but are also the best times to see whale sharks. Malaria has been reported on the island, so take proper precautions.
