The Vava’u archipelago is full of limestone islands with sea caves. This day trip visits the two best known and combines snorkelling and swimming in sheltered waters.
What you will do
- Cruise from Neiafu between islands and channels.
- Swallows Cave (Kapa): the boat or swimmers enter the cave, where blue light illuminates big schools of fish.
- Mariner’s Cave (Nuapapu): a cave with an underwater entrance; only swimmers confident holding their breath go in, with the guide. Others can enjoy it from outside.
- Snorkelling in a coral garden and a stop at a sandy beach.
Who it is for
Families and travellers looking for an alternative to whale swimming or a relaxed day at sea. Entering Mariner’s Cave is optional and only for confident swimmers.
What to bring
Swimwear, rash guard, towel, reef-safe sunscreen, warm layers and a waterproof camera.
Best time
All year, with steadier seas from May to November. In whale season (July-October) you will often see whales on the way, but this tour does not include whale swimming.
Good to know: Swallows Cave has old graffiti on its walls; please respect the site and avoid touching the rock. Sea conditions decide the order of the stops.
Included
- Boat with skipper and guide
