Mana island is one of 333 fijian islands, just a 4 hour boat ride from Nadi from about $50 return. Mana island is a lovely little island you can easily walk round in about 3 hours providing you're steady on your feet as you do have to clamber over rocks round some of the edges. The accommodation on Mana varies from budget to exclusive with the island having its own airstrip its a popular destination for families and honeymooners as well as backpackers. The island seems to be split in to 3 sections, the section where you arrive on the boat is where all the backpacker accommodation is, some more expensive than others. I stayed at 'Serenas' which was $35 a night with 3 meals included; the dorm rooms were basic as was the one cold tap used as a shower. Although the family that ran it were lovely and very helpful i wouldn't recommend it, the food was questionable, often cold, and I personally don't enjoy doughnuts for breakfast. The situation was similar next door at Mana Lagoon, although they have a small games room and the only shop on the island.
