A boat eases away from Jesselton Point and the water begins to take the city’s edge. Within 20–30 minutes the skyline thins and Sepanggar Island rises from the South China Sea—granite outcrops and green ridges that watch the reef below. The morning light makes the shallows read like a map: coral bommies, sand channels and the dark outlines of parrotfish and wrasse daring you closer.

Bring a Secure Mask and Snorkel
A well-fitting mask prevents leaks and lets you spend more time observing fish rather than clearing gear.
Mind Short Boat Transfers
