New Caledonia · Noumea and the southwest lagoon
Sheltered New Caledonia wreck dive on sandy bottom.
Sheltered New Caledonia wreck dive on sandy bottom.
Boat access and managed moorings make local operator support the normal way to dive here.
The Umbolt wreck in New Caledonia is a deliberately sunk fishing-boat site resting on a sandy bottom and leaning to starboard. It is a sheltered, easygoing wreck dive with good visibility on many days, and the structure attracts eels, moray eels, stingrays, turtles, lionfish, scorpionfish, shrimp, crab, and other reef life. The dive works best as a calm, guided wreck outing rather than an overhead penetration dive.
Site Conditions
Safety Notes

Legal Notes
Treat this as a managed wreck site; do not anchor on the structure and follow park rules.
Community notes to help plan your visit.
Scuba Diving
Wreck dive around 20 m on sand; the structure is well preserved and leans to starboard.
Freediving
This is a scuba wreck site rather than a freedive focus, especially if you want to explore the structure safely.
Snorkeling
The site is not a snorkeling destination in practice; the interest sits underwater around the wreck.
