Saleh Bay diving: when scuba makes sense with whale sharks

By Saleh Bay Whale Shark Editorial Desk

Saleh Bay diving with whale sharks is possible, but few visitors need it, because sources place encounters in the top few metres around bagans. Scuba mainly suits certified divers who accept the licence, distance and time conditions. A ministry guideline document asks for a recognised licence, three metres from the shark's side, and a 60-minute limit.

Is Saleh Bay diving worth it, or is snorkelling enough?

For the sharks alone, snorkelling is enough for most people. My Best Places to Visit, a travel blog, says most visitors only need to snorkel because the sharks feed just below the surface. Ocean Earth Travels, an operator, also places encounters in the top few metres around the bagan. Tanks do not get you to anything those two sources say you would otherwise miss at the platform.

What Saleh Bay scuba diving changes is your time under water, and the conditions attached to it. Dive Happy, a dive publisher, reports up to five sharks under one bagan on visits in 2024 and 2025, and suggests liveaboard divers often stay in for over an hour. That account sits awkwardly with the 60-minute limit described below, and you should ask any operator how it applies the limit.

Our guide to swimming with the sharks covers the snorkelling side. Ask an operator whether it runs scuba at the platforms at all.

What rules apply to divers?

The fullest national text cited here is a marine ministry guideline document. Its status is set out on the rules page linked below. It says:

• Divers and snorkellers stay no closer than three metres from the side of the shark.
• Snorkelling and diving are limited to 60 minutes. Boat-based watching is limited to 90 minutes, though the text writes 90 with the word for sixty, an evident typo.
• Tourists sign a waiver, and divers hold a recognised dive licence.

Separate from that document, Dive Happy warns against getting too close or being thumped by a tail, a hazard worth keeping in mind at any depth. Read our page on the rules for the local limits, and ask your operator which version it follows, because distances differ between sources. Nothing on this page is dive safety advice. Your training agency's limits and your dive professional's judgement apply.

A diver would normally ask about several things we cannot answer: recompression chamber access, medical care nearby, gear rental in the village, and which operators carry oxygen. Ask each of these directly, and do not assume a yes.

How deep is the water?

This is where sources look contradictory until you notice that they measure different things. Some give seabed depth at a point, one gives a maximum for the whole bay, and one delineates a protected area. None of them describes where you would dive.

For a diver, the practical reading is simple. Encounter sites can sit over deep water, yet the sharks at the platform are feeding close to the surface. Dive Happy accordingly describes the dive as shallow. How to plan a shallow dive over deep water is a question for you and your dive professional. Do not read the 400-metre figure as a dive site depth.

How warm is the water for a dive?

Warm by the figures available. The IUCN factsheet gives sea surface temperature of about 25 to 33°C for the area. The 2021 study measured 29 to 32°C on its trips between November and January, averaging 31.09°C. These are surface readings, so choose exposure protection on the basis of your own comfort.

On clarity, there is no published metres figure for Saleh Bay, so none appears here. SB Excursions, an operator, says wetter months push more runoff and plankton into the bay and make the water greener. Take any promised visibility number as a sales claim until someone can show how it was measured.

How big are the sharks you would see?

Smaller than the species' reputation. The IUCN factsheet reports that of 108 individuals identified, 99% were juveniles or sub-adults, and our count by year has the size figures. Dive Happy gives three to four metres on one page and four to seven on another. Even the lower figures make a large animal in the water, and the tail warning above applies at any size.

What else lives in the bay?

The bay holds more than sharks, though survey results are not a list of dive sites. The 2024 expedition reported by Konservasi Indonesia observed 560 reef fish species, while Antara reports 570 fish from an eight-day expedition. The two numbers differ by ten. The same expedition found mesophotic coral reefs at depths of over 30 metres. For the wider Saleh Bay whale shark background, see Saleh Bay whale sharks.

A reef that scientists documented is not necessarily one a dive operator visits, so ask your dive professional about depths over 30 metres. If reef diving is part of your plan, ask an operator which named sites it actually runs, at what depths, and with what experience required. Then decide whether the sharks or the reefs are the main purpose, since a dawn platform visit and a reef day may need different boats.

What do divers ask about Saleh Bay whale sharks?

Can you scuba dive with whale sharks in Saleh Bay?

Yes, on published accounts. Dive Happy describes divers in the water under bagans, and a ministry guideline document sets conditions for divers. Ask an operator directly whether it runs scuba at the platforms, since not every trip is sold for divers.

Do you need a dive licence for Saleh Bay whale sharks?

A marine ministry guideline document requires a recognised dive licence for divers. It is not confirmed as enacted, so check what your operator requires as well.

How deep is Saleh Bay?

Published figures measure different things. A 2021 study found seabed depths of 36 to 81.5 metres at its trip sites, and a 2025 paper gives a maximum of 400 metres for the bay. Sharks at bagans feed near the surface.

Is snorkelling enough for Saleh Bay whale sharks?

For most visitors, yes. My Best Places to Visit says the sharks feed just below the surface, and Ocean Earth Travels places encounters in the top few metres around the bagan. Scuba adds time under water, on stated conditions.

How close can divers go to Saleh Bay whale sharks?

The marine ministry guideline document says no closer than three metres from the side of the shark. Tail distances differ across other sources, and Dive Happy warns against being thumped by a tail.
