Route overview

Day trips from a coastal base, about 1h from the airport, then a short boat.

Airport options

DPS

I Gusti Ngurah Rai International Airport (Denpasar, Bali)

Direct international and domestic arrivals; road transfer of roughly 30-45 minutes to Sanur harbour, then a fast boat to Nusa Penida or Nusa Lembongan

Typical trip cost

$

under $2,000

Per person, excluding international flights.

  • Add the Nusa Penida marine protected area retribution of IDR 100,000 (about $6) for foreign visitors entering the water (IDR 10,000 for Indonesian nationals), the Klungkung island entry retribution of IDR 25,000 per adult and IDR 15,000 per child, and the one-off Bali provincial tourist levy of IDR 150,000 (about $10) paid via the Love Bali portal.

Permit or park fee

What you pay

IDR 100,000 (about $6) per foreign visitor to dive, snorkel or swim in the protected area, IDR 10,000 for Indonesian nationals, in force since 1 July 2023 under Bali Perda 7/2021. Separate Klungkung Regency tourism retribution of IDR 25,000 per adult and IDR 15,000 per child for entering Nusa Penida, Lembongan or Ceningan, formally applied from 1 September 2026 under Klungkung Perda 4/2026, which also charges IDR 25,000/IDR 15,000 at designated tourist attractions on the islands. The Bali-wide tourist levy of IDR 150,000 is a separate, one-off provincial charge paid via the Love Bali portal.

How it works

No dive permit as such, but the Nusa Penida marine protected area levies a per-person, per-day retribution on snorkelling and diving, collected by the Klungkung Regency government and the MPA management unit. Payment is now largely cashless. Diving is by licensed local operator; the MPA zoning plan reserves a 12.2 km² marine tourism zone in which fishing is prohibited.

Research is source-backed, but conditions and fees should still be confirmed locally.

View 12 sources and checking notes

Note on the data: Manta residency, site-level behaviour (Manta Bay foraging vs Manta Point cleaning and courtship), the April-May courtship peak and the 153% rise in boat traffic all come from the 2019 Frontiers in Marine Science photo-ID study. The 2012-2022 abundance trend (170 to 447) is from a 2025 Environmental Biology of Fishes paper whose full text is paywalled — only the abstract summary was read, so treat the exact figures as second-hand. Sunfish species identity (Mola alexandrini, not Mola mola) and the July/August-November encounter window are from the 2023 Frontiers in Marine Science photo-ID paper by the Bali Ocean Sunfish Research Project. Upwelling timing (June-October, southeast monsoon) and Nusa Penida SST are from published oceanographic and coral-proxy work. Thermocline figures of 18-20°C, and reports near 16°C, rest on dive-operator accounts rather than measurements — flagged in waterTempNotes. Fatalities and down-current incidents are documented in dive-media and forum accounts rather than an official incident register; the 2012 double fatality and Crystal Bay closure is reported consistently across multiple accounts but no primary coroner or authority source was located. MPA area, zoning and the retribution amounts come from the Coral Triangle Center and Klungkung Regency reporting; the underlying regional regulations (Klungkung Perda 5/2018, Bali Perda 7/2021) were cited in secondary reporting rather than fetched directly. Mola alexandrini has no confirmed published IUCN category — the IUCN Molidae review panel listed it as awaiting a first assessment — so it is coded unknown. All site coordinates are approximate positions from island geography and operator maps, not surveyed dive-site GPS. Water temperature: The maxC figures track reconstructed sea-surface temperature at Nusa Penida, which averages about 28.8°C in December-February and 27.8°C in June-August — the surface barely changes. The minC figures are interpolated to represent the thermocline divers actually hit during southeast-monsoon upwelling, widely reported at 18-20°C at Crystal Bay between July and October and occasionally near 16°C; those are dive-operator and dive-guide reports, not instrument records. Access: Fly into Denpasar (DPS), transfer 30-45 minutes by road to Sanur harbour, then a 30-45 minute fast boat to Toyapakeh or Banjar Nyuh on Nusa Penida, or to Nusa Lembongan; day trips from Bali run the same crossing and return the same afternoon. Independently verified 2026-08-28: Mola alexandrini identification CONFIRMED via Thys et al. satellite-tagging (clavus morphology; M. ramsayi is a junior synonym), and cons 'unknown' confirmed correct — the species is genuinely Not Evaluated, with no Red List record. Manta year-round residency and the Apr-May courtship peak confirmed. Corrections applied: waterTempByMonth had thermocline readings (18C) in a surface field with the caveat stranded in reviewNotes where it never renders — surface figures restored and the thermocline warning moved into waterTempNotes and visibility notes; sunfish window extended to December and July downgraded from peak; fees updated for Klungkung Perda 4/2026 (in force 1 Sept 2026) and the tiered foreign/domestic MPA retribution; the 2012 Crystal Bay deaths and the 2014 Lembongan drift-away stated precisely, with the site closure attributed as reported rather than confirmed.
