The Rainforest Discovery Center (RDC) is one of the most accessible natural rainforest in Sabah. It sits by a lake at the edge of the Kabili-Sepilok Forest Reserve in Sandakan. RDC has been in operation since 1996 for environmental education purposes. Today, it is a 3-in-1 park (i.e. wildlife, bird and plant) for nature lovers and bird watchers where they can see the unique flora and fauna of Borneo. To students, it’s the best outdoor classroom to learn the rich biodiversity of rainforest ecosystem.

Jungle Trails

Visitors can walk along the trails and become acquainted with green giants such as the mengaris tree, one of the tallest tree in Borneo. Besides soaking up the sight and getting a good workout, visitors can refer to the interpretive panels along the trail, which has descriptions about unique residents of the forest.

Alert the little ones to keep an eye out for darting civets and flying squirrels (which can glide up to 100 Meters)! And lucky visitors have also spotted animals such as the elusive red leaf monkey, gibbon (the fastest moving primate in tree canopy), mouse deer, civet cat and many odd looking insects such as stick insect.

Another tree worths a good look is Belian Borneo Ironwood (Eusideroxylon zwageri), the 7th hardest wood in the world.

Plant Discovery Garden

RDC also has a Plant Discovery Garden, which covers about 3 acres of land. This garden will make any botanist smile with its collection of hybrid orchids, arid land plants, aquatic plants, pitcher-plants, economic crops and tropical American plants.

For serious learners, there are just too many local and exotic plants (flowers, herbs, spices, crops) to look at, just to name a few, peach palm, vanilla, tongkat ali, rubber, cassava, cinnamon, fig, and cycad (a living fossil and food of dinosaur).

Canopy Walkway

The main attraction of RDC however, is of course the Canopy Walkway. Visitors can climb to the top of the observation towers and take in the breathtaking view from the 347-meter long and 25-meter high steel walkway.

Observatory towers of RDC

There are two observation towers (named as Bristlehead and Trogon Tower)

The walkway is two meters wide, is very sturdy and can hold the weight of a large crowd. RDC has two towers that are named after the Bristlehead and Trogon and a single-column shelter called the Sunbird.

The 40-meter white tree is mengaris tree (Koompassia excelsa), it can grow up to 86 M.

The designers of the canopy walkway made sure that it was not only safe for adults, but also for young children who are at kindergarten-level.

To the team at RDC, the younger children exposed to the wonders of Mother Nature, the better appreciation they will have for our rainforest.

The top platform of towers is about 17 Meters (56.5 feet) above the ground. Many birds, wildlife, fruits and insects live high on the tree, so these towers provide a great viewing point for bird watching and wildlife sighting. I’ve seen mother orangutan with her baby there before (see video).

Bornean Bristlehead normally feeds up in the mid and upper layer of tree canopy, and best seen from Canopy Walkway. You have higher chance of seeing them near Bristlehead and Hornbill Towers in RDC.

I’m very confident to say RDC has one of the best setup for bird watching in the world.

Many trees here are very old and over 50 Meters tall, most of these emergent trees are from the family Dipterocarpaceae, the main timber family of Sabah.

During fruiting season, you will see many birds and wildlife coming here for feeding.

Bird Watching

Due to the tourist-friendly canopy walkway and nearby virgin rainforest where over 300 lowland bird species reside, RDC is really a haven for nature photographers and birdwatchers. RDC is also the most promising spot to see Bornean Bristlehead, the trophy bird species of birders, but you still need some luck. I saw it only once after three visits.

Bird watching is a popular activity at RDC

Bird watching is the most popular activity at RDC. Bring a binocular so you won’t miss the fun.

Many endemic, rare and colorful birds are active around RDC, for example, Bornean Bristlehead, Hornbills, Pittas, Kingfisher (8 species), Trogons, Malkohas, Leafbirds, Minivets, Spiderhunters (6 species), Crested Jay, Red-bearded Bee-eater, Broadbills, Woodpeckers, and Bulbuls. For full list, you may see this Checklist of Birds in Sepilok.

Therefore, for visitors who don’t want to travel far, RDC is the best alternative birding sites to Danum Valley and Tabin Wildlife Reserve, the world-class birding sites in Lahad Datu.

Trails in Rainforest Discovery Center

Some forest birds spend most of their time on canopy and best to be observed from RDC Canopy Walkway, while some prefers habitat in understorey and forest ground, so you need to explore the jungle trails for such birds. (Note: leeches might present during wet season)

Birding trails of RDC

Birding trails of RDC

According to birding community, the 1.9-KM Kingfisher Trail is very productive (many birds). There are many direction signages in the RDC trail network, so you should have no problem to get around. What I really like is – RDC also places many information panels in different spots to inform you what birds, trees and wildlife are (probable) nearby.

Inside the forest there are small ponds used by many birds as natural bird bath for bathing and drinking. Most birds only dip their wings to splash water on their backs. Parts of the bath is just about 2 inches deep, just enough for small birds. Keep an eye for Red-eyed Bulbul, Emerald Dove and Hairy-backed Bulbul there.

This Exhibition Hall is air-conditioned, so I love to come here after a long walk under hot sun outside LOL (and for the toilet too).

I must say the Exhibition Hall does a very good job in giving visitors an interesting overview of Borneo’s nature.

Other Facilities

The infrastructure of RDC is quite well-thought, this makes RDC an excellent attraction, as well as a great location to organize mid-scale events.

Night Walk

Most wildlife are nocturnal. You may not see a lot of wildlife during daytime in RDC, but a night walk there would probably give you some pleasant surprises. Depend on your luck, you would see civet, moonrat, Malay badger, sleeping birds, glow worm, owls, stick insect, firefly, frog, bearded pig, flying lemur, etc. You hit jackpot if you spot Bornean Tarsier or Slow Loris, the most mysterious primates of Sabah. Known as Ghost Monkey locally, Bornean Tarsier is the smallest primate of Borneo and has huge eyes bigger than its brain.

    Very good post, hope you can write more environmental articles to bring up the awareness.

    My first thought when I saw the tall white tree with the tourist was: “Sabah’s own natural KLCC” 🙂

  • Rovdyr

    Do you mean that the profits from the sale of deforested not reach Sabah?

  • If it is illegal logging, then we won’t get a single cent.

  • TheSeer

    Yes, it is the greed in human beings that is destroying a lot of the world. It is not limited to certain politicians or corrupt individuals, but ALL of us are also vulnerable to this. We all need to watch our hearts and minds. This is why, many religions say, God wants to destroy the world because of the evil that mankind do, and the ones who will get the worst punishment are those who are in positions of power and they abuse it.

  • I agree with you TheSeer. We can say all what we want. But when we really face the temptation$, that’s another story.
