The best way to explore Dark and Bright Caves is by kayak and by swimming through tunnels, as the system of islets is imposing. Bright Cave is easier to navigate since accessibility does not depend on tide levels, whereas visitors to Dark Cave must mind the water levels. The area borders Halong Bay, Bai Tu Long Bay, and Lan Ha Bay.
