Crocker Range – a cycling adventure in the mountains of Borneo
Covered in lush green rainforest, the Crocker Range is a steep chain of mountains separating the east coast and west coast of Sabah.

The Crocker is the only real mountainous area in Malaysian Borneo, at an average height of 1,800 meters (5,900Â ft).Â
Mount Kinabalu, one of the highest mountains in Southeast Asia, is part of this range. Part of the range has been gazetted for protection as Crocker Range Park since 1984.
There’s a Rafflesia center here, where it’s possible to see the biggest flower in the world, as well as many hiking opportunities. One of the less-known things to do in Borneo.
This article is part of our “DIY Adventure Travel in Borneo” series. We crossed the northern part of the island from Kota Kinabalu in Sabah (Malaysia) to Pontianak in Kalimantan (Indonesia).
Crossing Brunei and the Malaysian state of Sarawak, in a combination of bicycle touring (mostly), boats and train (very short one). Check this if you want to know about cool cycling routes in Peninsular Malaysia.Â
Although the stereotypes of wilderness that most people have about Borneo will crash against the sea of palm oil plantations, the third-largest island in the world is still worth visiting. Adventure can still be experienced, and the people here are among the most amazing we have ever met.
This is the detailed description of the 1st part of our itinerary. Links to the other parts are at the bottom of this page, together with a map of the route with an elevation profile and a street-level photo map of the journey.

31 adventurous things to do in Borneo
Kota Kinabalu
We began our bicycle tour of Borneo in Kota Kinabalu, the capital of Sabah state, in the northeast of the island. Kota Kinabalu itself is not a great city; there’s a beach, but a stream of sewer cuts it in half, so I won’t bathe here.
The good beach is inside the university campus, a beautiful and big green area with some real rainforest and a white sand beach.
You may be asked for the documents at the gate, but security will hardly cause any problems. Other things worth checking out are the City Mosque and the so-called Filipino Market.
From the hills around the city, it is possible to get a good view of Mt. Kinabalu, the highest mountain in South East Asia (4,095 meters). Unfortunately, climbing is incredibly expensive (not less than 100 USD per person).
Check rates, prices, and fees here. Our friend John says it’s possible to bypass the checkpoint and climb it freely, but you’ll need the help of a local, and, of course, it’s illegal.
Opposite KK, there are a few islands, Palau Gaya being the biggest, apparently beautiful but with a dubious reputation.
From Kota Kinabalu to Tenom: the Crocker range – 171km
We decided instead to try a kind of climb we are more akin to, a bike one, across the Crocker Range. Many locals said we were crazy to try this, and well, it was a very tough one!
Just outside Kota Kinabalu, the road (road 500) is suddenly in a nice countryside, following a small stream where we can bathe, it’s 40 Celsius, as always in Borneo.
Around 12km out of town, the road begins to go slightly uphill, becoming steeper at km 20 and really steep at km 25.
There are almost no places to camp, so we pitch our tent after 5 more km, between a few dragon fruit plants along the road, careful not to touch the spikes. No places to eat or shops in this area either.
The next stretch is hell, a constant climb of 20km with an average gradient of 14%, but it’s also where the landscape really becomes interesting, with hills covered with jungle all around.
Here’s the one and only restaurant on this side of the mountain; miss it, and you’ll starve until the peak.
Reaching the highest point at 1,800msl is certainly an achievement, but you won’t be rewarded with any signpost indicating the pass.
Don’t be fooled by the first downhill, it’s just a few hundred meters long. There is still a soft uphill stretch of 2km. Then, the real downhill begins. It can be pretty chilly up here, especially when it rains, and we indeed caught a cold.
Some few kilometers after the downhill begins, there’s a hotel (I recall around 30 USD per night), a small shop, and a restaurant; a little further is the Rafflesia center, which was closed (we later managed to see a Rafflesia at Gunung Gading National Park in Sarawak).
Seven km down the top is also a botanical garden, which was under construction when we were here. The gate was anyhow open so we sneaked in and set our camp in a sheltered gazebo, rain was hard all afternoon and night.
Still, 13 more km of steep downhill to reach the town of Tambunan, where there’s a supermarket. We crossed the Crocker!
Tambunan to Tenom
The next 20km is an easy flat with not much to see but the beautiful sky of Borneo, which never disappoints. Then iit s up and down for 36km to Keningau, a fairly large town with everything you need.
This stretch offers some free camping spots, so we opted for a bridge to be sheltered from the night rainfall. It makes terrible noises, though.
Past Keningau, there are 10km of claim, which themselves are not so hard, but the achy legs and upcoming fever made it quite a nightmare for us.
On the top of this hill, there are market stalls to buy fresh fruit. The downhill is not so relaxing, still some up and down for ten km, before the last flat 20 to Tenom.
Tenom
Tenom itself is not beautiful, but it’s an interesting place to visit. Famous for fruits and especially coffee, the best thing to do here is indeed visit the farms (Sabah Agricultural Park) and the coffee factories.
Of the 55,000 population, 60% is ethnic Murut. In the center, there’s a statue of Ontoros Antonom (1885–1915), who, in 1915, led the Muruts against British colonists in the Rundum village of Tenom.
We visited the Yit Foh coffee factory, had some great coffee for free, and saw how they toast the beans in the traditional way: in iron cylinders hand-rolled on wooden fires.
From Tenom, it’s possible to catch the 100-year-old North Borneo Railway to Beaufort (or further to Kota Kinabalu). This is not just a train but a real experience, we dedicate a special article to this.
