Nissan island
Nissan Island Guesthouse
A handful of rooms here on very remote Nissan Island. There is no way to book as there are no communication lines to this island. It seems unlikely that they would be full if you just turned up!
There are two other guest houses on Nissan both at Tartumpos Balil. Kulu Guest House situated right at the tip, and Balil Lodge nearby. For the same reason of lack of communication, you cannot book and they receive very few guests.
