Mulu, Sarawak: Of Cave-Hopping and Spelunking

“What you wanna do for your birthday, Jo?” I asked my BFF.

I cross my fingers and hope for “get pissed drunk”, although half a can of cider beer does it for her (true story).

Instead she says, “caving!”

And that’s how we ended up in Mulu, Sarawak.

DAY 1- the arrival and botanical heritage trail

We voyaged over a tropical rain forest via an ATR 72 into a plane of viridescent vegetation. The earlier departure into Mulu was significantly delayed due to mist, rendering a visual approach unfeasible. So I sigh with relief when our 20 minutes flight conclude seamlessly (from the perspective of a passenger, discounting all possible undisclosed cockpit complications).

At the arrival hall, a nice girl named Diana stood patiently with an A4 paper- “CP LEE & JOANNE LIM” printed in capital letters. Walter from CBS’s Scorpion once said that “there’s an endorphin release you get from seeing your name on a sign at the airport. It’s an indication of forethought.” I concur.

Diana drives for 5 minutes before we arrive at our home base for the next 3 days- Mulu National Park.

We check in at the park’s office where we’re tagged, then presented a map and room keys.


I’m amused by this T-shirt and it’s accompanying note that says “adhere to the park’s regulation… to safeguard you from keeping 120 professional Sarawakian Search & Rescue members busy for days AND you don’t have to print a silly T-shirt!”

Point taken: a T-shirt is a very unflattering place to have your face plastered.

A++ for witt
Our temporary residence- the Palm bungalow.

After dumping our baggage, we pull on sensible shoes and venture out for an evening stroll. The sky hints at a chance of rain, and sun sets at 6pm in East Malaysia. Therefore, of the unguided tours, we picked the Botanical Heritage Trail for it’s length (only 1.5km) and proximity- being stuck under the pouring rain in the dark is not on our bucket list.

The wooden pavement

The entire trail is covered with a wooden pavement. Trees line each side of the track, with limited sunlight exposure. The walk is easy and relaxed, the perfect setting for a poet’s soul; or 2 gossiping 20s girls.

We make a couple of new friends along the way:

Mr. I-am-an-allergen
Ms. my-tail-is-longer-than-yours

Trees, unidentified insects, nasi lemak, and canopy walks- these are the staples of a Malaysian national park.

We set course on the same wooden pavement we sauntered along on Day 1. Here, we encounter a huge tree, probably older than Noah and his ark. Oh, if trees could talk!

After 2.5 km of leisure trekking, we arrive at canopy walk.

I’ve experience numerous canopy walks, the last documented one being this at Taman Negara, Pahang. Yet, the thrill never gets old- suspended from multiple tree trunks, caressing the treetops, like a passageway into a hanging Eden.

Every national park needs a canopy walk.
Being suspended 50feet above the ground by wooden planks and flimsy ropes never gets old.

Alas, the highly anticipated moment has arrived- tummies full from lunch, we board the little speedboat that will journey us to Racer Cave for our spelunking adventure.

Wind in my face, the occasional murky water in my mouth, ahhh… I love boats!
Far away, the misty mountains call… Spot the Gwaihir

After 20 minutes, we arrive at Racer Cave. Here, we slap on yellow safety helmets, headlamps and strap into safety harnesses. Attached to the harness is a rope, each end equipped with a carabiner.

After a short safety brief, our group advance into the stony unknown with caution. But first, we squeeze through a tight and narrow opening between the rocks. I suck my tummy in, and curse every cheese cake I’ve ever indulged.

Thank goodness, I wedge through uneventfully.

I turn around, and darkness nods. Our headlamps and peeping light through the rock fissures act as sole light sources. In fact, later during the tour, the guide prompts us to switch our headlamps off. As a result, patent blackness envelopes. I couldn’t see an inch ahead of me, and all I could think of was, “is this how David hid from King Saul??”

We climb rocks, sometimes with a rope’s help, mostly freehand. As a lukewarm rock climber, I rate these ascends 5a- doable by any abled body person with basic locomotive functions. The advertised “intermediate level” sounds about right.

At one point, we repel down one and half storey of rocks. A rope permanently looped around a sturdy rock act as anchor while the guide belay us down. As each person reaches the base of the rocks, he/she throws the carabiner back up, and the act is repeated till everybody is safely lowered.

We even get a stingy view of the cave’s namesake- the racer snake. This belt-like reptile binges on bats and birds, we learn. No rats, the guide assures us.

On top of that, we also get a healthy look at the “Mulu Cappuccino”. The guide grabs a handful of what resembles black soil and parades it to our little group. Jo whips out her camera and is about to snap when the guide says with a wink, “it’s bat poop.” HAHA!

We continue to traverse rocks and scale others. I thank God for that yellow miner’s helmet that saved me from concussion at least half a dozen times.

Yup, that helmet!

The cave has only one way in and out, which is unfortunate. A route loses its charm once you’ve conquered it. But becoming cavewomen is not the plan, so we backtrack where we entered. This, however, given its declining gradient, proved to be an onerous feat.  Indeed, that was exactly what I spat, grip working overtime.”This is an onerous feat!” I declared. “Yes! I did just say that while hanging from a rock for dear life!” I continue loudly to aware the bats of my anguish.

But I didn’t die… which was a relief… phew! What did happen though, was a comical tumble that followed my attempt of leap off the rock like cat woman. Our guide managed the jump effortless, making it look easy.

Mimicking him, I ready myself, knees bent, and sprung off a rock with burning confidence… landing flat in a pile of unidentified brown “fluff”.

And that was the end of my humiliation… not.

Our 2 hours expedition approached the finishing line. Having slip right back through the initial crack, sunlight is beaming on our faces.

After living 2 hours without a ray of sunshine, I’m ecstatic. I quicken my pace down the rocky terrain, arms raised in victory. “We survived!” I proclaim.

I smell the sun… freedom… I feel the wind… I feel…

… the lack of solid ground under my feet?

I’m tripping! I’m falling! I’m rolling…

Picture credit:

… Yep, just imagine me in place of that cute cartoon log…

… Once again, the yellow miner’s helmet is my saving grace.

DAY 3: SHOW CAVES- wind cave, LADY CAVE, and clearwater cave.

After 2 hours of navigating through bat poo, and making ladders out of rocks, we still insist on spending Day 3 in more caves. This time, however, we stick to show caves- those with solid, beautifully paved routes and man made lights to lit our paths.

The first show cave on our agenda is the wind cave. It’s name is derived from a spot in the cave where wind blows in at varying velocities.

Mid cave, a crack of sunlight spills into the cave from a hole above:

“Where did the hole come from?” The tour guide asked. “Why, this asteroid, of course!” Then he gestures at this rock:

The “asteroid”

No, not really, he rights the story. It’s some science-y stuff about rain water. But I prefer the asteroid tale.

Lady Cave is named such due to a stalagmite that cast a womanly shaped shadow. In my honest opinion, though, that conclusion requires quite a lucid imagination.

The stalagmite and its shadow that gave Lady Cave its name.
I have a sudden urge to play “chopsticks” on the piano.
A random phallus
The king’s chamber
One of these stalactites could impale a person. Just saying.

The Clearwater cave, as its name suggest, has crystal clear water. This cave also have a hefty flight of stairs that overly satisfies my daily cardio requirement. But that climbing wasn’t for nothing, thanks to this rewarding view:

Clearwater Cave
Clearwater Cave again
Clearwater Cave on repeat

Advance spelunking starts here, we learn. Cavers swim considerable distances in the freezing water:

And then it’s time to ascend more stairs:

Uhuh, climb them steps.
“It’s holy water!” says the guide.
We might not have peaked the Mulu Pinnacles, but here’s a mini version of those glorious limestone formations.

After all those dark, dingy caves, it’s time to photosynthesise. So we take a dip in a pond of Clearwater’s chilly water.

(Okay, full disclosure- we city kids sat on the steps leading into the pond for eternity. I said “Jo, we need to stop being the embodiment of city kids”, after which, I took a step down, then spent another 5 minutes shivering from the cold water. We then tried to visually gauge the depth of the water. Jo even attempts a step of faith, then quickly retraces when her feet couldn’t meet the bottom. Only after a couple of Sabahans boldly plunge into the water, do we leave the city on the wooden steps and soak in mother nature.)
