BANDA BESAR & KARNAFOL ISLAND
We only visited the snorkelling site of Karnafol on Banda Besar. Again, it's good and highly recommended.
GUNUNG API & KARATA ISLAND : again, good snorkelling, though not as exceptional as the other islands. Best for a relaxed half-day trip from Bandaneira, or to cool off after you've climbed Gunung Api (!! see below)
