Gunung Mulu National Park. A gentle jungle.

Sungai Melinau Paku River, with the mountains of Mulu peak in the background.

I suspect I’m not the only one who assumes that the jungle of Borneo will be so full of bugs waiting to feast on me that I’ll be slapping and scratching from the moment we arrive in Mulu.

Arrival at Mulu Airport.

Was that my biggest worry about our four nights in Mulu? Well, after our experience at Mt. Kinabalu I was also worried about leeches. And, for our first guided tour at Mulu both Rich and I wore sneakers, long sleeves and trousers to keep the bugs away. Our wonderful guide, Nim, was wearing shorts and hiking sandals. For every tour after that we wore shorts and sandals as well. So much more comfortable in the hot and humid weather. And so few biting bugs. We have the millions of bats and swifts to thank for that.

Our first very rainy afternoon. All the rain meant no bat exodus the first night.
A frequent site during the rain, yellow poncho clad visitors.
Fog at the mouth of the Deer Cave, where millions of bats shelter during the day.
Rainwater drips through the limestone to create amazing sights in the Deer and Lang Caves.
From the boardwalk you get to see stately trees.
Rich added for scale. This is a day or two after arrival when we had learned that shorts, t-shirts, and sandals were the way to go.

The two biggest attractions at Mulu are the caves and the bats. We jumped right in to cave tours, ultimately getting to walk in five caves, for a total of about 5 or 6 kilometers of cave walking. Wow, impressive right? Well, Gunang Mulu National Park has about 295 kilometers of explored caves. Every cave we visited was different, the giant chambers, amazing drip structures, or no drip structures due to wind blowing through a cave and inhibiting the fantastical structures.

Boats waiting to load visitors for a cave tour.
The boat rides were a fun way to start a tour.
A young helper, his Dad is handling the motor, he helps out at the dock and on debris watch, so the visitors don’t end up in the river.
At the entrance of the Cave of the Winds. A boat ride and 200 stairs up.

A sky hole in the cave. With light comes life.
After visiting Clearwater Cave you get to swim in the river that flows out of the cave. Incredibly refreshing.

Each cave is unique. And some have only been open to visitors for the last few decades or so, which means that they are pristine. Fastlane cave has had the lightest human touch, with no lights installed and a through route – in one mouth and out another – and the most dramatic formations.

On the way to Fastlane Cave.
The entrance. Flashlights are really needed in this cave.
Photography is a little challenging, you have to borrow torchlight.
A “showerhead” formation. Water drips through the limestone deposits, which were perhaps created by tree roots up above.
Over hundreds of years the shower head has created its own basin, or bathtub. The water is incredibly pure, but of course reaching in to it is strictly prohibited.
The size of the group is limited to 8 on the Fastlane Tour and our guide, Jonah, was super knowledgeable. He also had us all turn off our lights for a few minutes to really experience the cave as its inhabitants do.
Like these huge Huntsmen spiders who live in the cave and eat crickets. We also saw blind white cave crabs, blind cave crickets, swifts flying and navigating by clicking, and of course bats.

There are trails for self guided hikes, but to enter the caves you must be with a guide.
Gate at the cave exit. I was very amused by the spider web motif.
Inside the Cave of the Winds, in this photo you can see the boardwalk and lights.

The bats disappointed us our first evening, but on our second evening, we hustled out the 40 minute walk from the Park Office to the bat pavilion and settled down hoping for no rain and many bats.

We all did a pretty good job of being quiet.
The bat pavilion was the place to be, a lively global crowd on the Lunar New Year
And the bats came out. And out. And out. Millions of bats. In waves and waves. They flew overhead and circled back. You could hear their masses of wings beating.

We also did the canopy walk. 25 meters up, 425 meters long, and apparently the longest tree based canopy walk in the world. The guide warned us it was not for those with a fear of heights. Or a fear of swinging swaying narrow walkways. The guide also warned us not to drop our phones as the locals would retrieve them for us, but would also charge for retrieval. A river retrieval would of course cost more than a jungle floor retrieval.

Heading out, two by two, per instructions. A fellow tourist took this photo for us. We all took photos of each other and shared via Airdrop.

The Canopy Walk was a success.No cell phones were dropped.

Mulu Park is quite well run. We had no problem signing up via email for tours in advance (recommended!). There was plenty of staff on hand to check you in for tours. The tour guides all came from local communities, and knew traditional customs and ways of life since their families lived them. Facilities were well kept up, the park cafe was open 7:30 to at least 8:30 and the food was pretty good.

Where were we when not walking through caves in Mulu? At the Mulu Marriott. The hotel was only about a six minute drive from the park, by frequent on-call shuttle van or open air truck. There are also options available inside the park, hostels or lodges, and home stays just outside the park and right across the river from the Marriott. Something for any budget, really.

Loading up the human cattle car. It was actually quite nice. A breeze. A view. Your fellow hotel guests.
Bamboo shaded walkway at the Marriott. The entire hotel is built up from the jungle floor on boardwalks and stilts.
Rich chilling waiting for the shuttle to the park.
Enjoying a glass of wine in the River Bar. Not only was this a great place to bird watch, but it was also the only place to get connected to WiFi.
The Travel Planner hard at work, binoculars at the ready for bird spotting.
Breakfast outside at the Marriott, binoculars still ready for bird peeping.
The resident cat family. Ever hopeful for food.
Little girls are always a good bet for tidbits to the cats.
And nice young men, apparently. The cats migrated from table to table.

We settled on Mulu National Park as a place to be over Lunar New Year, it seemed a good way to escape the crowds and noise of the cities and festivities. It was a great decision, peaceful, busy but not super crowded, and we had the pleasure of meeting a lot of other visitors. When you’re all staying at the same hotel, and doing the park tours, you get to know the other folks. Quite a few families who were living and working in Brunei had come to the park. It was nice to have opportunities to chat, exchange notes on the tours, and just socialize in general. That is something we can miss out on doing constant travel, the social part of life. All the ex-pat families were so friendly. I suppose it’s a necessity when you relocate for work, get out and make friends wherever you are. We appreciated it very much and loved chatting with folks.

Two sweet girls from Egypt, Dad is an anesthesiologist in Brunei. We got to know this family over a few tours and in the hotel.
Dave and Eileen (hi you two!) from Aberdeen. We shared beers and bat watching.
And a few tours.

Four nights was a nice length of time. We could have filled a few more days, there were more walks to do, and for those who crave more adventure there were adventure cave tours, which involved crawling and squeezing and sometimes swimming through caves. Squeezing not for us but two nice American guys we met had a fantastic time on a cave adventure. They were exhausted and filthy but had signed up for another one so obviously enjoyed it.

Cleaned up and ready for dinner.
The happy travelers ready to leave Mulu.

Next up: Miri and Kuching. Kuching is known as the city of cats, so you know what to expect from me!

After decades of living and working in wonderful San Francisco we gave it all up to travel the world. Not owning a car allowed us to save money and live hyper-locally. Now we’re living around the globe. Follow along to see where we are and what cats I manage to pet.

    1. These caves are so well done, walkways and some mood lighting, super visitor friendly for the most part. And the bats! So wonderful. At our hotel bigger bats were cruising the open air hallways at night! Right over our heads! Loved it 😊

  1. “With light comes life” – I hadn’t ever really seen it that way before, since I moved to California as a kid in a drought year and thought the issues hostile to “life” were too much light and not enough water. It took you going into a cave with your camera to give me a new perspective!

    1. It’s so dramatic to go from the barren looking cave to the skylight. You feel as if you’ve never seen green before! I was right next to our guide and said “wow!” (Yes, so eloquent!), and he said that “with light comes life.”. Really liked the guides.
