Diving is one of the main draws of the gorgeous Keramas. It's always advisable to do your research online and book ahead, but if you've not been able to do that, drop into Joy Joy, which usually has helpful English-speaking guides on staff.

Whale-watching is possible between the months of December and April. For more information, either enquire at the tourist information office or call the Zamami-mura Whale-Watching Association, which has one to two tours daily (two hours).
