The trails and the wildlife spotting opportunities in Mulu are pretty good, but it's the caves you really come here for!
I couldn't recommend the advanced adventure caving tours here highly enough, but you won't be allowed to do them unless you have booked in advance and have some previous adventure caving experience... or are willing to do one of the parks intermediate adventure caving tours such as Racer or Stonehorse Cave on your first days at the park so the guide can assess your ability or lack thereof. Some visitors will not have the agility and fitness level required to participate in an advanced caving tour.

My favourite tour was the advanced Clearwater Connection tour. This 5km underground tour will take approximately 5-6hrs and involves tight squeeze's, traversing ledges and drops through two connecting caves (the stunning Cave of the Winds and the awesome Clearwater Cave). For the final 1.5km you can choose to either walk alongside the underground Clearwater river or allow yourself to be carried downstream by the flow of its shallow waters.

The Garden of Eden tour would be my second favourite. It's a full day 5-6hour 12km trek. It's a stunning walk and you get to see more of Deer Cave than you would on the standard show walk as you go all the way through the cave, wading through chest deep water at one point (see photo). The tour is vulnerable to cancellation by the guides in wet weather because of this river crossing. At the end of the tour you visit Lang cave, which is nice but underwhelming by the cave standards in Borneo. Then you have the choice to hang around for the bat exodus or head back to the park headquarters.

Tip: bring a spare torch, not just for the caves but also for the Night trail loop. As this is one of the shorter trails in the park you don’t need a guide to hike it. I seen more wildlife on this loop after dark than on any of the other trails in the park.

We have just returned from 2 nights at Mulu, having purchased a package deal. On our afternoon arrival at the airport we were met by our guide, Andy, and transferred to our hotel (The Marriott), and then started on our afternoon tour to Lang and Deer caves. We loved the c 3km walk in along well maintained boardwalks through virgin jungle. Both caves were easy to walk through on the walkways and suitably lit (although a torch can be helpful). We were lucky enough to be at the caves late in the afternoon so our group of 4 plus guide were the only ones in each cave, and we left Deer cave as the bats were already departing. We sat for a while at the observation area just watching the twisting ribbon of departing bats in the sky.
The next morning we started early at 8am on a boat trip to Wind and Clearwater caves. The stop at the Penan village was interesting and the information boards and small handicraft market worth seeing. Our early start meant that again we had the caves to ourselves. In my view, Wind cave was the most spectacular, but each of our group had a different favourite!! Then we had time for swimming in the crystal clear but very cold river before lunch provided at the rest area.
The Marriott is a great place to stay if you want a little luxury, and 24 hour electricity with aircon, but prices are high for drinks etc (not surprising given the logistical challenges of being in a place with no road in or out!). There are a few local cafes around, but no real nightlife and most places only have electricity for a few hours each evening (so take a torch in case you need to get up in the night!).
We were very impressed at how well organised and maintained everything is and highly recommend a 2 or 3 night visit here, even though it is not cheap with airfares and package costs.

The show caves in the Mulu National Park offer adventure for people of all ages and fitness levels.
The easiest part is the Lang and Deer Caves which are reached from park HQ on a wooden plank walk. Since the bats exit the Deer Cave in the late afternoon the tours are scheduled to depart from HQ at around 2pm which leaves enough time to explore the caves. Concrete foot paths and sturdy wooden and metal stairs and bridges allow for easy exploration of the caves.
Unfortunately for us, there was a heavy downpour at around 4.30pm and the millions of bats did not exit the cave on that particular day.
Make sure you bring a rain poncho and a dry t-shirt for the return trip just in case you get drenched like we did. You will be back at park HQ by 7pm.

The trip to the Clearwater and Wind Caves takes a bit longer. The first part of the journey is by longboat from park HQ to the landing pier at the Melinau river at 8.30am. There is usually a stop over at a Penan long house so don't forget to bring some cash. The handicrafts are of high quality and we liked the leather wrist bands which were a big hit with our nieces and nephews.

Exploring the Clearwater and Wind Caves require climbing up a steep plank walk and wooden staircase through the limestone cliffs.
Inside the caves there are plank walks and stairs, including a new walkway along the top of Clearwater cave which offers a spectacular view. I used the setting for handheld night view on my Olympus camera and got great shots.

Lunch is usually served at the end of the tour on a wooden deck overlooking the Melinau river. Swimming in the clear and cool water fed by the underground river emerging from the cave is possible but be aware of submerged logs.

The return trip by long boat to park HQ usually takes 1/2 hour and one should reach there by 2pm.

Fabulous place to visit but BEWARE! If you want to stay in the park itself you have to book and pay a deposit in advance. This must be at least 10 days before you visit. We booked, paid the deposit, sent proof of payment, however it still hadn't cleared by the time we arrived, so despite having all the evidence at my end to show them, I still had to pay full amount for the accommodation. They said they would refund the deposit and that it would take a month. It has been 6 weeks and I am still waiting... very disappointed. Also this is not world standard safety (which I like) so choose your adventures carefully :)
