Batu Bolong

Two answers, because that is two questions. Across the year, the dry months from roughly April to October give the clearest water: a Labuan Bajo dive centre publishes visibility of about 20 to 30 metres on northern and central sites in that window, falling to around 10 to 15 metres during the December to March plankton blooms. Water temperature stays in the mid to high twenties Celsius, coolest around July to September. Within a given day the answer is slack tide, and slack moves. Your crew picks the window from tide tables the day before. You do not get to pick it from a schedule.

Strong enough that the entire dive plan is built around avoiding it. Current hits the pinnacle head-on and splits, and the sheltered lee that forms behind it is the only part of the rock that gets dived. Depth follows the plan rather than the rock: guides commonly work around 18 to 20 metres, published maximums range from 20 to 35 metres depending on which source you read, and the wall itself continues past 70 metres into the channel. Recreational limits apply regardless, and on days when the life is shallow the plan gets shallower with it.

Sometimes, and published guidance disagrees. One Labuan Bajo dive centre states that Open Water divers can dive it in mild to moderate current, and recommends Advanced certification only once flow exceeds roughly two and a half to three knots. A widely used dive-site database describes the site as suited to advanced or experienced divers because of the currents. Both are describing the same rock on different days. What every source agrees on: buoyancy control matters more than the card, Discover Scuba participants are not permitted, and if you were certified last week this belongs later in the trip rather than on day one.

Usually, but confirm it. Dive day trips and liveaboard fares from Labuan Bajo normally include national park entry, and park access is booked through the SIORA system rather than paid at the site. What varies between operators is whether every component sits inside the headline price — park entry, marine tourism charges, ranger fees. Ask for the breakdown in writing before you pay. Fee levels have changed repeatedly, so treat any figure you find on a blog, including a recent one, as unconfirmed until your operator states it.

A day trip works. Central Komodo day boats from Labuan Bajo include Batu Bolong regularly when conditions allow, usually alongside Tatawa or Manta Point, with a run of roughly one to two hours each way. What a day boat cannot do is choose the tide. It arrives inside a fixed schedule and takes whatever window falls in it, along with the rest of the day fleet. A liveaboard sleeping in a nearby anchorage can be on the site for the first slack of the morning. If Batu Bolong is the reason you came to Komodo, that is the difference you are paying for.

No, and the mix-up is common because both places genuinely carry the name. The Bali one is on the Canggu coast: a temple on a rock outcrop and the beach beside it, a surf and sunset spot with no diving involved. This page is about the Komodo pinnacle in the Lintah Strait, a flight and several islands away. The name simply means rock with a hole in Indonesian, which is why it appears in more than one place. Within Komodo itself, Batu Bolong is also regularly confused with Castle Rock and Crystal Rock — those are separate pinnacles in the north of the park, with their own conditions.

Almost certainly not, and this is the thing most travel pages still get wrong. Several dive operators state that snorkelling is prohibited here. One describes a regulation introduced in 2019 that capped daily dive boats and stopped snorkellers swimming at the site. Another lists snorkelling and Discover Scuba as not allowed, both to protect the shallow reef and for safety. A Komodo resort states that park authorities banned it after repeated incidents. Against that, some snorkelling roundups still list Batu Bolong as accessible to strong snorkellers, at least one park-regulation summary describes it as a diving and snorkelling zone, and older travel blogs describe superb snorkels there. We have not seen the regulation text itself, so we will not call it settled law. The practical position is not ambiguous: the operators who actually work the site say no, their reason is that a snorkeller on the surface in that channel has no way to control where they end up, and a crew willing to drop you there without a tank is not a crew to reward. If you snorkel and want similar water, Manta Point and Siaba Besar are the shallow alternatives every operator does run.

Roughly one to two hours by boat, and the spread is real rather than sloppy. A fast dive boat quotes about an hour, day-boat operators typically budget closer to two, and slower phinisi hulls take longer again. The site sits in the Lintah Strait in the central part of the park, near Tatawa and within a short run of Manta Point and Siaba Besar, which is why it is almost never dived on its own but as one tank of a two or three dive day.
