Batu Bulan - Perhentian Islands
Batu Bulan sits at a comfortable 14 metres, making it a good spot for newer divers or those looking for a relaxed afternoon. We’ve drifted along here often, spotting plenty of damselfish and parrotfish grazing on the reef. It’s a gentle introduction to the Perhentians’ calmer side, ideal for getting back into the swing of things. Don't expect dramatic drop-offs, just a pleasant, easy dive.
