Diving Wallis (Uvea) - Lagoon & Outer Reef

About Wallis (Uvea) - Lagoon & Outer Reef

Wallis, known locally as Uvea, is the northern heart of the Wallis and Futuna territory and the most accessible place to dive in this remote French Pacific collectivity. A massive barrier reef encloses one of the largest and most pristine lagoons in Polynesia, sheltering calm coral gardens, turtle-grazed bommies and the three navigable passes that connect the lagoon to the open ocean. The shallow lagoon coral gardens are perfect for relaxed exploration and macro photography, while the passes - Avatele on the west and Hihifo on the north-east - funnel strong tidal currents that bring grey reef sharks, eagle rays, dogtooth tuna and swirling barracuda. Beyond the barrier reef the seaward wall drops vertically into the deep blue, draped in sea fans, black coral and soft corals, and patrolled by silvertip sharks and schooling pelagics. The island also hides Lake Lalolalo, a perfectly circular freshwater crater lake that has attracted technical divers drawn to its sheer limestone walls and submerged forest. With no commercial dive centres, diving here is a self-supported or expedition affair, but the reward is reef systems in a state of remarkable, near-pristine health. Visibility routinely exceeds 40 metres, and the warm, clear water makes Wallis a true frontier for intrepid divers.

Highlights

• ✓Uvea Lagoon Coral Gardens: shallow, calm table-coral and Porites bommies inside the barrier reef
• ✓Avatele Pass: the main west-coast channel with sharks, eagle rays, tuna and current-swept walls
• ✓Hihifo Pass: a narrower, less-dived north-east pass with similar pelagic action and drift diving
• ✓Wallis Outer Wall: a vertical seaward drop-off with black coral, sea fans and silvertip sharks
• ✓Lake Lalolalo: a circular freshwater crater lake for advanced technical divers

Getting There

Fly into Hihifo Airport (WLS) on Wallis from Noumea or Nadi with Aircalin, then base in Mata-Utu. The lagoon sites are reached by private vessel or local boat from Mata-Utu or Hihifo; the passes and outer wall require a boat capable of handling open-ocean swell. There are no dive centres, so all gear and a compressor must be self-provided or arranged with an expedition.
