A Santubong river cruise is a boat trip out of the Santubong estuary that runs from afternoon into dark. It costs RM200 to RM290 a head on a 2026 join-in ticket with hotel pick-up from Kuching, and the evening runs about 5 hours door to door, from a 3pm to 4pm pick-up to a hotel drop-off between 8pm and 9pm. The Irrawaddy dolphins are the lure and they are never guaranteed, so the dependable part is the mangrove hour at dusk, when proboscis monkeys settle into the trees along the channels.
The sensible way to book is to treat the dolphins as a likely bonus on top of a river-and-mangrove boat ride, because a blank night costs the same as a good one. Every Kuching operator sells much the same boat with a different brochure, so the differences that matter are the jetty, the clock and the price.
What Does the Santubong River Cruise Actually Involve?
The boats leave from the Santubong peninsula, mostly from the Sarawak Boat Club at Kampung Santubong, and the first leg is a run of about 20 minutes to the river mouth, where the Santubong and Salak rivers meet the sea and the dolphins feed. From there the boat turns into the mangrove channels of the Salak delta for proboscis monkeys at dusk, switches to a torch for crocodile eyes once it is dark, and stops under a stretch of firefly trees before the run home. All of it sits in the wetlands below the mountain park that looms over the estuary, which is why “wetlands cruise”, “Santubong cruise” and “mangrove cruise” on a booking site are the same product.
Which Operator, From Where, and for How Much in 2026?
Seven listings cover almost every way to book the cruise, and the six join-in tickets among them sit in a band from about RM200 to RM290 for an adult. The table is built from operator and reseller pages checked on 1 November 2026, plus one reader’s receipt where an operator hides its own price.
| Operator | Departs from | Time | Price 2026 | Notes |
|---|---|---|---|---|
| CPH Travel | Sarawak Boat Club, Kampung Santubong | Afternoon, pick-up about 4pm | About RM200 to RM260 via resellers; confirm direct | Its own price page would not load, so the figure is unverified |
| Borneo Adventure | Sarawak Boat Club | Pick-up 3.45pm to 4.15pm | From RM260 adult | Minimum 2 adults; a morning dolphin cruise is from RM240 |
| Borneo Travel Network | Sarawak Boat Club | Departs 4.30pm, 4 hours | RM260 adult, RM145 child | Rates valid to 31 December 2026 |
| Amazing Borneo | “Santubong Jetty”, 20-minute transfer | Pick-up 3pm to 3.30pm, drop-off about 8pm | RM290 adult, RM145 child | Join-in; the page shows RM290 beside a struck-through RM390 |
| Paradesa Borneo | Village jetty inside the wetlands park, 35-minute drive | 4pm pick-up, about 4 hours | About RM218 to RM225 adult, RM109 child | Morning cruise at 8am from RM210 |
| Ooo Haa Adventure Tours | Launch just outside Santubong National Park | Dinner on board about 6.30pm, back before 8.30pm | About RM200 (one May 2026 booking) | Listing itself not found |
| Telaga Air boatmen | Telaga Air jetty | 5pm to 7.30pm | RM500 to RM530 per boat of 1 to 5 | Private boat, own transport; RM30 per extra person up to 8 |
A “from Kuching” ticket buys the van and the guide, not a better boat, because the boats and jetties overlap, so the cheapest ticket with a sane pick-up time is the sensible one. Permai and Damai guests can book the same ride through their resort without the drive, and the resort desks usually quote the same RM200 to RM300 band , which is worth asking about if a stay is already booked (). A Grab out to the boat club costs RM45 to RM70 one way, and it only makes sense with a plan for the return, since Grab drivers thin out after dark and the boat lands at 7.30pm to 8pm. Visitors who tried the Telaga Air jetty on their own make the same point: take a car, because finding a car back is the hard part. (see reaching Santubong without the operator van)
For a family of five, the Telaga Air private boat works out at RM100 to RM106 a head, below the join-in rate, at the price of a car and a fixed 5pm slot. Telaga Air and Samariang are the two other launch points into the wetlands park, but most operators use Santubong or Damai because they are closer to Kuching. Fishermen at Buntal, on the east side of the peninsula, ran informal dolphin trips in the past, and nothing there is bookable online in 2026.
If you want a price confirmed before you commit, Google Maps listings (checked October 2026) show CPH’s office at 70 Jalan Padungan open 8.30am to 5pm Monday to Friday, 8.30am to 12pm Saturday and closed Sunday, and Paradesa at 1 Lebuh Wayang open 9am to 6pm Monday to Friday, 9am to 1pm Saturday and closed Sunday. The Sarawak Boat Club listing, at Santubong Bridge, Kampung Rampangi, carries no opening hours at all, which suits a working dock.
When Should You Go: Afternoon, Dusk or Dark?
The standard cruise runs from about 4pm to 8pm because each animal wants a different light. Dolphins are looked for first, on the falling light at the river mouth, proboscis monkeys come down to the mangrove edge as they settle at dusk, and fireflies need full dark. Pick-up is between 3pm and 4pm, the boat is on the water between 4.30pm and 5.15pm, and the jetty comes back around 7.30pm to 8pm, so plan on reaching your hotel between 8pm and 9pm.
The morning version exists for the dolphins alone. It leaves around 8am to 8.45am, returns by about 11.30am, costs RM210 to RM240 on the join-in operators and RM500 on the one small-boat operator that lists it, and runs in calmer water with no fireflies. Guides say mornings are close to certain for dolphins and evenings about 50/50, though visitors who did both on the same day disagree about which was better, so treat the claim as what guides say, not a statistic. A morning cruise also frees the afternoon for a daytime stop at the Sarawak Cultural Village on the same road, and the 4.30pm boat leaves room for a beach afternoon first (a Damai day pass before the 4.30pm boat).
When Is the Best Season for Irrawaddy Dolphins?
The odds are best from about April to September and worst in the northeast monsoon, and nobody agrees on a peak month. Two operators do not run dolphin cruises at all from November to February because of the swell, while others list year-round departures, and one fact file puts the dolphin season at March to October. A CPH guide told the Borneo Post in 2019 that sightings follow the fishing season between January and June, which is when the dolphins work around the fishing boats hauling in their catch. One 2026 reader says June and July are the best months. Those three claims overlap but do not agree, so book for the dry months and expect a coin toss in the months either side. The monsoon months in Kuching are the ones to avoid if the dolphins are the whole reason you are going.
Heavy rain and rough sea are the two standard reasons an operator cancels. Listings say the trip is rescheduled or refunded, and one CPH guest was rebooked after a storm kept the boats in. Tide matters too: listings describe sightings as dependent on tidal conditions, and crocodiles show on the mud banks at low tide.
What Will You See, and What Might You See?
Plan for the first two lines of this list and treat the rest as upside.
- Long-tailed macaques: certain, usually on the first mangrove bend.
- Proboscis monkeys: near-certain at dusk, with reports ranging from 2 to 15 or more on a trip.
- Fireflies: usually, and modest, from a few flickers to a stretch on both banks.
- Irrawaddy dolphins: likely in season, never promised, and grey, stubby and shy, surfacing for a second and gone rather than riding the bow.
- Estuarine crocodiles: occasional, found by torch at low tide as a pair of red eyes, or as a ring of bubbles where one just went under.
- White-bellied sea eagles and kingfishers: common along the channels.
- Bioluminescent plankton in the wake: one 2026 report on a dark night, so not something to plan around.
If the monkeys are the point rather than the dolphins, Bako’s proboscis monkeys on the boardwalks are the more reliable sighting, in daylight and without a boat.
What About Children, Mosquitoes, Rain and the Ride Home?
Infants ride free (age 2 and under on one listing) and children aged 3 to 11 pay RM105 to RM145, so a family of four with two small children pays closer to three adult fares than four. Most join-in listings ask for a minimum of two adults per booking, and Borneo Adventure charges a surcharge for a single traveller. The boats are open or canopied longboats carrying about 6 to 16 passengers, and life jackets are compulsory.
Bugs board with you at dusk. One 2023 passenger felt them the moment she stepped on the boat and said repellent worked, and listings add a torch and a raincoat to the bring list. Where dinner is included, the packed meal is basic: one passenger’s chicken noodles were more bone than chicken. There is no toilet on the boat, and the toilets at the Sarawak Boat Club draw repeated complaints on Google Maps (checked October 2026), so go before you leave the hotel.
The ride home is fast and dark. One passenger found it a little scary, though the boat carried a big light on the water, and a 2026 account calls the boats fast enough to catch everyone off guard.
What Is the Honest Downside?
The dolphins. Some trips get a family for 20 minutes, some get a single fin, and some get nothing at all, and the price is the same on a blank night as on a good one. At RM290 each, two adults pay RM580 for a boat ride that may end with no dolphin photograph. The ticket also buys less time on the water than it suggests: a 4-hour package is mostly the van, and the cruise itself runs about 2 to 2.5 hours, which one guest counted at only 1 to 1.5 hours and called too short for spotting dolphins.
The guide is the other lottery. Reviewers name favourite guides by first name, and one 2023 visitor sat through the dolphin search with a guide who barely spoke until the fireflies.
So Which Santubong Cruise Should You Book?
Book any licensed afternoon join-in in the dry season, pick by departure point and pick-up time rather than brochure, and go in the morning if the dolphins are the whole point. Go in with the framing from the start of this page: a likely bonus on top of a river-and-mangrove boat ride. For the hike, the beach and the one road in, the rest of the Santubong peninsula is covered in the main guide, and the other day trips out of Kuching are the fallback if the weather calls the boats off.
A blank night costs the same RM290 as a good one, and the monkeys at the mangrove edge at dusk are the part of the ticket that reliably turns up.
