Rainforest Skywalk of Rainforest Discovery Center (RDC)

Rainforest Discovery Center (RDC), a Park in the Jungle

The Rainforest Discovery Center (RDC) is one of the most accessible natural rainforest parks 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 botanical) 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 tropical rainforest.

The 4,300-hectare Sepilok-Kabili Forest Reserve has gained birders recognition worldwide for its iconic Bornean Bristlehead, Black & Crimson Pitta, Blue-headed Pitta, Giant Pitta, Black Hornbill, Rhinoceros Hornbill and more. The forest of Sepilok is declared as an Important Birding Area (IBA) by Birdlife International in 2009.

Jungle and Nature Trails

Visitors can walk along the trails and become acquainted with green giants such as the 40-Meter-tall 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 the 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 and lantern bug.

Another tree worths a good look is Belian Borneo Ironwood (Eusideroxylon zwageri), the 7th hardest wood in the world. The main trails are gravel path, and some sections are networks of well-trodden nature (soil) trails for you to explore deeper.

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 rich collection of hybrid orchids, arid land plants, aquatic plants, pitcher plants, economic crops and tropical American plants.

Rainforest Skywalk (Canopy Walk)

The main attraction of RDC is Rainforest Skywalk, the longest Canopy Walkway in Sabah. Visitors can climb to the top of the observation towers and take in the breathtaking view from the 620-Meter-long and 25-meter-high metal platforms and walkway.

The walkway is two meters wide, is very sturdy and can hold the weight of a large crowd. RDC has three main towers that are named after the Bristlehead, Hornbill and Trogon and a single-column shelter called the Sunbird. With a height of 26.5 Metres (87 ft), Trogon Tower is the highest tower of RDC.

Rainforest Skywalk of Rainforest Discovery Center
Rainforest Skywalk of Rainforest Discovery Centre is tall but still lower than many trees. Some of the trees were planted in 1970s and 1980s.

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.

Fruits of Rainforest Discovery Center

To the team at RDC, the younger children are exposed to the wonders of Mother Nature, the more they will appreciate our rainforest. During weekends, some local retired people also come here for birding regularly.

Rainforest Skywalk of RDC
Rainforest Skywalk of RDC is 620 Metres long after an extension of 250 Metres completed in early 2022.

The highest platform of towers is about 26.5 Meters (87 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).

Orangutan and Macaque
Orangutan and Macaque could be seen at RDC, especially during fruiting season. They are not friendly so keep a distance from them.

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. On the skywalk, you don’t need to look up so much that your neck cramps. I’m confident to say that RDC has one of the best setting 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.

Birdwatching and bird photography
Birdwatching and bird photography are popular activities at RDC. Do bring a binocular with you.

Many endemic (13 species are Borneo 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.

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)

Interpretation panels of birds in RDC
Interpretation panels of birds in RDC are placed at the spots where sighting of birds in the pictures are possible. Some are placed on Rainforest Skywalk for birds that are active on canopy.

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. Garden birds such as sunbirds, spiderhunters and flowerpeckers are common visitors too.

Borneo Bird Festival
Borneo Bird Festival is packed with activities for birders, children, photographers and tourists.

RDC is a preferred venue for Borneo Bird Festival, which is usually held in Sep or Oct annually, the best visiting time for bird watchers who are looking forward for exciting activities such as bird race, talks, bird photography contest, latest birding gears, and exhibition.

Exhibition Hall

The main visitor building has an exhibition hall that features the unique flora found in Sabah, plus the various icons in our animal kingdom including the Bornean pygmy elephant, orangutan, proboscis monkey and many more.

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. They also added a 180-Metre flying squirrel zipline at the lake area.

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.

  1. 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” 🙂

  2. 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.
