Proboscis Monkey and Fireflies River Cruise
Book on Viator →Operated by TYH Borneo Tours and Travel SDN BHD · Bookable on Viator
Fireflies turn the river into a light show. This sunset mangrove cruise pairs that magical twilight scene with wildlife-focused boat time near Kota Kinabalu, aiming for proboscis monkeys and other jungle characters.
I especially like the wildlife commentary—it helps you understand what you’re actually seeing instead of just guessing. I also appreciate the included food setup, with afternoon tea plus dinner so you’re not left hunting for snacks at the worst possible moment.
One thing to keep your expectations realistic: proboscis monkey sightings aren’t guaranteed, since wildlife moves and timing matters.

Key things to know before you go

- Sunset boat cruise with a built-in shift from daylight wildlife spotting to night-twilight fireflies
- Wildlife commentary covering proboscis monkeys, silver leaf monkeys, long-tail macaques, monitor lizards, and native birds
- Included snacks and dinner, so you can spend the full evening on the water instead of planning meals
- Small group limit of 20, which usually makes the experience feel more personal than a big bus-and-boat shuffle
- Round-trip shared transfer from your hotel area, with extra fees only if you’re farther out
A sunset mangrove cruise that fits your timing in Kota Kinabalu
This tour is built around the best part of the day: late afternoon fading into night. You start at 1:30 pm, then you’re on the water when animals become more active and when the river starts to glow with twilight.
That timing matters. During daylight, wildlife spotting is about movement—trees, shorelines, and quick sightings near the waterline. By sunset, your eyes start hunting for different cues: blinking points of light, slow drifting glints, and the overall “everything quiets down” feeling that comes with evening mangroves.
And yes, fireflies are the star attraction once the light drops. This is the kind of tour where you’ll feel the shift from daytime “look for animals” to nighttime “watch the sky and waterline for flickers.”

Getting there: shared transfer, small group size, and outskirt pickup fees

Logistics are pretty straightforward. You get hotel pickup and drop-off plus an air-conditioned vehicle, and the transfer is round-trip shared. With a maximum of 20 travelers, you’re not going to feel lost in a crowd—more like a small group outing.
The one cost wrinkle: if your hotel is outside Kota Kinabalu city area (and outside the 1 Borneo Shopping mall area), there’s an added MYR30 per person for pickup. It’s not a huge surprise, but it’s worth checking before you fall in love with the idea of a super convenient door-to-door start.
Also keep in mind that you’ll use a mobile ticket. Make sure your phone is charged and your ticket is accessible offline if needed. This tour runs on tight timing, so “finding the right screen” shouldn’t become your personal adventure.
Food on board and between stops: tea, coffee, snacks, and dinner

One underrated part of this excursion is how they handle food. You’ll get afternoon tea plus coffee and/or tea, along with local snacks. Then dinner is included too.
Why this matters: mangrove and wildlife evenings can run long and you’ll likely be focused on spotting wildlife instead of thinking about what you’ll eat next. The included food keeps you from scrambling for cash, finding a restaurant mid-program, or cutting the boat time short because you’re running on an empty stomach.
The best way to use this setup is simple: eat when you’re offered the break, then plan to snack lightly afterward. You want your energy steady for the sunset and twilight viewing.
The Weston wetland focus: why proboscis are the headline

The route and area you’re working around includes Weston, a town on Sabah’s west coast, about 100 kilometers south of Kota Kinabalu. The important detail here is what Weston is known for: the Weston Wetland and its large proboscis monkey population.
Now, here’s the key reality check. Proboscis monkeys are famous for a reason, but they’re still wild animals. Even with a targeted wetland area, sightings depend on movement, weather, and what the group’s timing lines up with. That’s why I recommend treating proboscis as the bonus—while still being excited to spot them.
On this cruise, your guide’s job is to help you “read” the shoreline and water edges. Proboscis often show up where the ecosystem supports them, so the boat route and commentary are part of the hunt, not just background entertainment.
Wildlife commentary that turns guessing into noticing
This tour’s boat time isn’t just “sit and look.” You get educational commentary on local species, including:
- Proboscis monkeys
- Silver leaf moneys
- Long-tail macaques
- Monitor lizards
- Native birds
Having a guide explain what you’re likely seeing changes the experience fast. Instead of scanning randomly for movement, you learn what kinds of animals might appear near mangrove edges, why they choose certain spots, and what behaviors to watch for.
It also helps with the “when you’re disappointed” problem. If you don’t catch a clear proboscis view, you can still leave feeling like you understood the mangrove world you cruised through. That’s one reason this tour can feel great even when wildlife timing isn’t perfect.
One more human detail: a guide named Terence was specifically thanked for sharing local land and nature with lots of energy. I can’t promise who you’ll get, but it’s a good sign that the guiding style can be more than reading a script.
Sunset on the water: mangrove scenery and the rhythm of the cruise
The cruise happens through mangrove forests near Kota Kinabalu. Mangroves are the real workhorse of this ecosystem: roots grip muddy ground, shorelines shelter wildlife, and the whole area changes character as the day cools.
You’ll typically notice how the boat pace shifts. Early on, you’re scanning for quick animal signals—small head movements, sudden runs, or flashes of color through leaves. Later, it becomes slower and more observational, because twilight changes everything: visibility, shadows, and the mood of the water.
This is also when the sunset becomes part of the show, not just a clock event. A beautiful sunset is more than pretty photos; it’s part of why wildlife spotting feels different after light fades. Even if animal sightings are brief, the atmosphere stays worth it.
Fireflies at twilight: how to get the best viewing
If you came for the fireflies, you’re in good company—this is the most praised element of the experience. The “blinking” starts as the sky darkens, and it’s at its best when you let your eyes adjust instead of chasing every spark like it’s a fireworks show.
Here’s how to make that happen:
- Keep your phone use minimal once twilight hits.
- Give your eyes 1–2 minutes to adjust to lower light.
- Watch the waterline and nearby mangrove shadows, not just the open sky.
Because the viewing depends on natural conditions, you can’t force perfect firefly timing. But you can control your focus. When you quiet your screen time and stay patient, the river starts to feel alive with tiny signals.
This is also where the cruise format helps. Being on the water means you’re closer to the habitat where those lights appear, instead of viewing from a distant shore.
Is it worth $81? Value vs. what’s actually guaranteed
At $81 per person for about 8 hours, you’re paying for four main things:
- Round-trip transport (pickup, shared transfer, drop-off)
- A guided wildlife-focused boat cruise
- Included food and drinks (tea, coffee/tea, local snacks, and dinner)
- A timed sunset-to-twilight experience centered on fireflies
So the value isn’t just “a boat ride.” It’s the full package: the planning, the route, the commentary, and the meal coverage that makes it easy for you to commit to the schedule.
The main variable is wildlife. Proboscis monkeys may be the headline, but they’re still wild. If you’re the kind of person who needs a guaranteed animal sighting every time, you should know that no nature tour can promise it.
Still, when a tour includes sunset atmosphere, fireflies, and helpful explanation of what lives around the mangroves, you’re likely to feel you got your money’s worth—because you’re not relying on a single animal to make the night work.
Who should book this cruise (and who should think twice)
You’ll love this tour if you:
- want a nature evening with a clear schedule and included food
- enjoy wildlife watching but prefer guidance so you learn what you’re actually spotting
- are excited by fireflies and twilight scenery more than “must-see” species certainty
- like small-group outings (up to 20 people)
You might think twice if you:
- are coming primarily for proboscis monkey photos and feel uneasy about not seeing them
- dislike being on the water during low light (twilight is part of the experience here)
- don’t want any extra pickup fee risk if you’re outside Kota Kinabalu city area or beyond the 1 Borneo zone
Should you book Proboscis Monkey and Fireflies?
Yes, if you want a smooth, guided sunset mangrove cruise that treats wildlife viewing like a learning experience and ends with a strong chance at an unforgettable firefly display. The included transport and meals make the schedule easy to commit to, and the small group size keeps it from feeling like a factory product.
I’d book with one mental adjustment: plan to enjoy the whole ecosystem and the twilight moment, not just one target animal. If the proboscis are shy, you’ll still have the sunset atmosphere and the firefly show—which is, frankly, the part you’ll remember.
