Castaway Island Fiji is surrounded by white sandy beaches but also vibrant coral reefs. Take a second to look at its location on the Google map and you’ll see just how close it is to the lagoon and barrier reef. Castaway Diving, the resort’s own Castaway dive shop, offers both plenty of sheltered diving in the warm clear waters surrounding and adjacent to the island, but also plenty of exciting stuff on the barrier reef. You’ll be enthralled by hard and soft corals, spectacular walls, swim-throughs, reefs and pinnacles, and moray eel and shark encounters all within minutes of Castaway Island aboard their purpose-built dive boat: Sokia.

Sokia, which means angelfish in Fijian, is a 30-foot aluminum monohull dive boat, powered by twin 200 hp outboard engines, making her one of the fastest and most stable dive platforms in Fiji. Sokia is fully surveyed, safety equipped and comfortably accommodates 14 divers, speeding them to a host of spectacular dive sites along the barrier reef.

Being a PADI Five Star Gold Palm Dive Centre, they offer the full suite of PADI dive courses, starting with Bubble-maker, a scuba experience for children in a pool with lots of fun games to play and the emphasis on safety. Minimum age is eight years.

They also have packages available so that you could you can pre-book, for example, a six tank dive package, saving considerably over buying individual dives and spread your six dives across your week’s stay.

What to expect

When first arrive head down to the dive shop and discuss the type and amount of diving you’d like to do with the DM. You’ll be surprised at the variety of diving available across the 28 dive sites they have listed. From Vonu Range (Vonu of course meaning turtle), to Castaway Pass – a drift dive on the outside of the barrier reef wall with a good chance of seeing pelagics, to Supermarket, famous for its sharks, to Big W, another drift dive with tunnels and swim throughs.

Different sites suit different divers, and chances are the deeper dives will be the first ones with shallower and easier dives in the afternoon. There are three departures each day, so you can pick and choose when you want to dive.

Once checked in for a dive, your gear will be outside the shop ready for you to carry it down to the boat. The cylinders simple click into the holder behind the benches that run the full length of Sokia. As it is one tank per trip there’s plenty of space.

You can expect to be at the selected dive site and ready to enter the water within 20 minutes of leaving Castaway’s beach, and if you’re going out to the nearby Three Bommies dive site you’ll be there in just three minutes.

The crew and dive guides are there to help and will make sure everyone is well briefed and comfortable during the trip. Entry is via giant stride off the platform at the back and re-entry via the broad ladder.

At Castaway Diving, they make it so easy: all the dive sites are so local and accessible they are probably the most ideally suited dive operation in the Mamanuca Islands region. The whole round trip is usually about 90 minutes, so going for a dive doesn’t take you away from the family for too long.
