Permit or park fee
What you pay
Mabul and Kapalai lie outside Sipadan Island Park and Tun Sakaran Marine Park, so no marine park fee applies to local diving. Sipadan day trips cost non-Malaysians RM 350 per day for the Sabah Parks diving permit plus RM 100 conservation fee (Malaysians RM 250 + RM 50), per person per Sipadan day, with an optional RM 50 per day camera fee on top.
How it works
No permit is needed to dive Mabul or Kapalai themselves: the permit system applies to the Sipadan day trip, which is why most people come. Sabah Parks controls Sipadan access and permits cannot be bought by individuals: around 40 registered tour operators apply on guests' behalf, may book up to six months ahead with a 50% deposit, and Sabah Parks states that issuance is solely at its own discretion. The daily quota is reported at 254 permits (divers and snorkellers combined) across all operators, raised from 176 shared between 24 operators when Sabah Parks widened the operator list in 2022: the current figure is consistently reported by operators and Sabah news but is not published on the Sabah Parks site itself. Permits are distributed to guests on rotation, so staying at Mabul or Kapalai does not guarantee a Sipadan day: resort packages typically bundle one Sipadan day into a 4-night stay and two into a 5-night stay, and most resorts want a minimum of 3 nights before they will commit to a permit. Since May 2026 a permit covers three dives at Sipadan rather than two. Sipadan closes entirely for the whole of November each year for reef recovery; Mabul and Kapalai keep diving through it. The 254 figure is consistently reported by operators and Sabah news but is not published on the Sabah Parks site itself, and some 2026 guides still quote the pre-2022 figure of 176: treat it as the working number, not a guarantee.
