Flamboyant cuttlefish on black sand at Mabul Island, Borneo

Mabul: The Macro Capital of Borneo

Julian Marsh·February 10, 2026·9 min read

Sipadan's quiet neighbour is one of Asia's richest muck-diving sites — frogfish, mimic octopus, flamboyant cuttlefish, all within fin-kicks of the jetty.

While most divers come to Mabul for the boat ride to Sipadan, the seasoned macro lover knows the real treasure is right under the resort jetty: black sand, artificial reefs and a roll-call of weird that rivals Lembeh.

House reef and night dives

Most Mabul resorts have a house reef accessible by walk-in or short boat hop. Frogfish (giant, painted, hairy), mimic octopus, blue-ring octopus, mandarinfish at dusk and bobtail squid at night — all in 5–12 m of water.

Boat muck sites

Eel Garden, Paradise II, Lobster Wall and the artificial reef structures around the island all offer different macro themes. Local guides are exceptional — most have spent 20+ years on these sites.

Combine with Sipadan

The classic Sabah trip: 3 days Sipadan + 2 days Mabul macro. Stay on Mabul and let the boat come to you for both.
