Proboscis Monkey and Fireflies River Cruise
The best part of this outing comes after dark, when fireflies flicker through the mangroves and turn an ordinary river ride into something memorable. Before that, you cruise near Weston in search of proboscis monkeys, silver leaf monkeys, long-tailed macaques, monitor lizards, and native birds.
I like the simple all-in format: hotel pickup, dinner, drinks, snacks, and a guide are covered. I also like the slow change from daylight wildlife watching to a sunset river cruise and then fireflies. The main catch is that monkeys are wild animals, not scheduled performers. One booking resulted in a beautiful sunset and excellent fireflies, but no proboscis monkeys at all.
Key points to know before booking

- Weston is about 100 kilometers south of Kota Kinabalu, so much of your afternoon is spent getting to and from the wetland area.
- The cruise has two very different moods: daylight wildlife watching, followed by sunset and fireflies.
- Proboscis monkeys are not guaranteed, even though Weston is known for its large population.
- Terence is one named guide associated with the tour, praised for explaining Sabah, nature, and local culture with care.
- The shared vehicle carries up to 20 people, which keeps the price moderate but makes this less private than a custom trip.
- Outskirt hotel pickup costs an extra MYR30 per person, including hotels outside central Kota Kinabalu and the 1 Borneo Shopping Mall area.
The real draw: a river that changes after sunset

This is not a quick city excursion. You leave Kota Kinabalu at 1:30 pm and head toward Weston, a town on Sabah’s west coast in the Interior Division. The destination sits roughly 100 kilometers south of the state capital, along the Pan Borneo Highway.
That distance matters. You are signing up for about eight hours door to door, not eight hours on the river. The long transfer is part of the price of reaching the wetland habitat, so I would choose this trip only if you are happy to trade an afternoon and evening for a chance to see wildlife in a more natural setting.
The outing is built around timing. Daylight gives you the best chance to spot animals in the mangroves. As the light softens, the river becomes a good place to watch the sunset. After dark, the focus shifts to fireflies. That progression gives the tour a clear rhythm instead of one long, repetitive boat ride.
The fireflies are the most reliable reason to book. They are also the part that can make the long ride worthwhile, especially if your main goal is a memorable evening in Sabah rather than a guaranteed animal checklist.

Getting to Weston from Kota Kinabalu

Pickup begins around 1:30 pm. Round-trip transport is provided in an air-conditioned vehicle, and the transfer is shared with other people. The maximum group size is 20, so you should expect a social outing rather than a private guide and car.
I see the shared setup as a fair compromise at $81 per person. A private vehicle would give you more control over timing and probably more space, but this package removes several separate costs. Hotel pickup and drop-off, the driver-guide, local guide, boat cruise, afternoon tea, coffee or tea, and dinner are included.
The outskirt policy is worth checking before you pay. Pickup from hotels outside the Kota Kinabalu city area or the 1 Borneo Shopping Mall area costs an additional MYR30 per person. That is not a major charge, but it changes the final price and should be included when you compare this outing with other wildlife trips.
Confirmation is provided at booking, and most people can take part. The available information does not promise special transport arrangements or a particular level of physical access, so contact the operator before booking if you have mobility needs that require specific assistance.
Why Weston matters for proboscis monkeys

Weston has become known for its wetland habitat and its large proboscis monkey population. These strange-looking monkeys are one of Sabah’s most distinctive animals, with their oversized noses and reddish-brown coloring. They are also the reason many people choose this particular river trip.
The wildlife commentary helps put the search into context. Your guide may point out proboscis monkeys, silver leaf monkeys, long-tailed macaques, monitor lizards, and native birds. The tour is not only about spotting an animal and moving on. The stated focus on local wildlife means you should expect explanations during the outing, with guides such as Terence adding information about Sabah, nature, and local life.
Still, keep your expectations in check. One person on the tour saw no proboscis monkeys and felt the boat spent too much time moving up and down the river. That criticism is fair. A wetland cruise can involve patience, repeated scanning, and stretches when nothing obvious appears.
I would treat monkey sightings as a welcome reward, not the product’s only measure of success. If a proboscis monkey is your absolute priority, you may prefer a trip designed around wildlife photography or a private guide who can spend more time searching. If you enjoy the whole sequence, the outing works better: river, sunset, food, commentary, and fireflies.
The daylight river cruise
The boat ride takes place in the mangrove forests near Kota Kinabalu, in the Weston wetland area. The daylight portion is your best opportunity to look for monkeys and birds, while monitor lizards may appear near the water or along the banks.
The pace is likely to feel slow, and that is useful. Wildlife watching rarely works when you rush from one point to another. You need time to scan branches, muddy edges, and patches of vegetation. The supplied information does not specify the boat type, seating arrangement, or exact cruise route, so I would not book expecting a particular vessel or photography setup.
The guide’s commentary is one of the practical strengths. It gives you something to listen for while the boat moves, and it can help you understand why the animals are in certain areas. Terence received specific praise for making Sabah’s nature and culture easier to understand, which is exactly the sort of human touch that improves a basic wildlife trip.
The less appealing side is that the commentary cannot create an animal sighting. You may spend time cruising without seeing the species you hoped for. That is normal in wildlife tourism, but it is worth saying plainly because the name of the trip puts the proboscis monkey first.

Sunset on the mangrove river
Sunset is the visual high point of the daylight portion. The cruise is timed to bring you onto the river as the afternoon fades, giving you a chance to watch the colors change over the wetland.
One person who had an average wildlife outing still considered the sunset beautiful. That detail matters because it shows where the experience can succeed even when the animal search does not. You are not paying only for a monkey sighting. You are also paying for an evening setting that changes by the minute.
Bring realistic expectations. A sunset depends on weather and visibility, and no exact sunset viewing point is given. The tour does include a boat cruise at sunset, but it does not promise a clear sky or a particular photographic view. I would enjoy the moment rather than build the whole booking around a perfect picture.
Coffee, tea, and local snacks are included, along with afternoon tea. These small comforts matter on a long afternoon away from the city. You are not left to arrange food while waiting for the next part of the cruise.
Fireflies after dark

The firefly portion is the strongest reason I would recommend this experience. Once the sun is down, the boat moves through the darkened wetland while fireflies blink in the trees and along the river.
The effect is quiet and unusual. You are no longer scanning the branches for a monkey. Instead, you are watching small points of light appear and disappear in the twilight and darkness. One account of the outing called the fireflies amazing, and that praise fits the experience’s design: the tour saves its most atmospheric moment for the end.
The exact viewing conditions can vary, and the supplied details do not promise a certain number of fireflies or a particular length of time among them. Still, this is a clear advantage over a daytime-only wildlife cruise. Even if the monkeys stay hidden, the night section gives the trip another way to succeed.
I would also remember that darkness changes the experience. You may see less of the river itself, but the lack of detail is part of the appeal. The fireflies become the focus rather than one more item in a busy program.
Food, drinks, and the value of $81
At $81 per person, this is not the cheapest way to spend an evening in Sabah, but the package includes more than a boat ticket. You receive hotel pickup and drop-off, shared round-trip transport, an air-conditioned vehicle, a local guide, a driver-guide, the river cruise, afternoon tea, coffee or tea, snacks, and dinner.
The included transport is important because Weston is far enough from Kota Kinabalu that arranging your own vehicle would add both cost and planning. You also avoid figuring out how to connect a city transfer with a wetland boat operator.
The price makes the most sense for people who want a ready-made excursion. You leave the city in the afternoon, reach the river, eat during the outing, and return after the firefly cruise. The downside is less control. Shared transport means you follow the group’s schedule, and the overall eight-hour duration can feel long if wildlife watching is not your thing.
The food details are broad rather than specific. Dinner is included, but no menu is provided. Afternoon tea, coffee or tea, and local snacks are also included. If you have dietary needs, ask before booking rather than assuming the included meal will suit you.
The tour is often reserved about 13 days ahead, which suggests that planning early is sensible during busy periods. Do not forget the cancellation rule: the booking is non-refundable and cannot be changed for any reason. That makes it especially important to confirm your hotel location, date, pickup eligibility, and meal needs before payment.
Who will enjoy this tour most
I would recommend this for someone who wants several Sabah experiences in one outing. You get a long-distance countryside transfer, wetland wildlife, a sunset cruise, local food and drinks, and fireflies. Families and first-time visitors may appreciate the simple arrangement and included transport, provided everyone is comfortable with a full afternoon and evening.
It also suits people who prefer interpretation rather than independent wildlife searching. A local guide can explain what you are looking at and fill the quiet stretches on the river. The positive account of Terence shows how much the guide can shape the day.
This is less suitable for a strict wildlife photographer who needs a private boat, a flexible route, or guaranteed time at a particular location. It is also a poor fit if you dislike long shared transfers or need to keep your evening free.
Most people can participate, and the maximum group size is 20. That is small enough to avoid a huge coach excursion, but you should not expect an intimate private experience.
Should you book the Weston river cruise?
Book it if you want the full evening package and understand that nature sets the schedule. The fireflies, sunset, included dinner, and door-to-door transport give the $81 price solid value, especially for a first visit to Kota Kinabalu.
Book with caution if the proboscis monkey is your only goal. Sightings are not guaranteed, and one outing produced no monkeys despite time spent searching the river. In that case, look for a more specialized wildlife arrangement or consider a private option.
My practical call: choose this tour for the combination of experiences, not for a promised animal count. If you can accept a quiet river ride, a possible miss on monkeys, and an excellent chance of ending the night with fireflies, it is a worthwhile way to see a quieter side of Sabah.
