More ways to explore the area's outdoor wonders
Wet air bites at the surface as the boat eases away from Radazul’s harbor and the island’s volcanic flank slides beneath you like layered basalt. Descending here is a descent into black rock, sculpted channels and pockets where marine life collects—turtles cruising along ledges, stingrays half-buried in sand, and clusters of nudibranchs decorating cracks.
