Onna Point

Divers enter through a crevasse into a labyrinth of narrow channels, swim-throughs and tunnels that one dive centre compares to flying through a canyon. Large coral colonies hold anemones with clownfish, angelfish, wrasses, stonefish and octopus, and turtles are often seen. A four-wheel-drive vehicle is recommended for the access road. Rip currents can make the exit difficult, so less experienced divers should go in at high tide.
