Récif Tabu is a sheltered reef near Nouméa with a gentle sandy slope, a rocky drop-off on one side, and the Toho 5 wreck below the main reef. It works well as an easy boat dive when the lagoon is calm, because the start is straightforward and the site gives you a simple reef-to-wreck progression without a complicated swim. Expect reef fish, jacks, whitetip reef sharks, and occasional lionfish around the wreck.
