More ways to explore the area's outdoor wonders
You step off the small flight into Mulu and the air changes—humid, green, and alive. A narrow plank walk threads through lowland dipterocarp and kerangas forest for about 3 km, ending at the yawning mouth of Deer Cave where, at dusk, a river of bats pours into the sky and the cliff faces seem to breathe.

Expect a 3 km plank walk
The primary access to Deer and Lang’s Caves is a raised wooden boardwalk of about 3 km—wear sturdy, closed-toe shoes and expect wet or uneven sections.
Plan for dusk bat viewing
Bat exodus is best watched at dusk; bring a light jacket and arrive early to secure a good viewing spot without blocking paths.
Protect against rain and insects
A lightweight rain jacket or poncho and insect repellent are essential—tropical rains can start suddenly and mosquitoes are common near water.
Carry a dry bag for electronics
Longboat transfers and rainforest humidity mean phones and cameras need waterproof protection—use a small dry bag.
Sturdy trekking shoes
Closed-toe shoes with grip for plank walks, muddy trails, and stairs in cave areas.
Light rain jacket or poncho
Sudden tropical showers and splash during longboat transfers make waterproof outerwear indispensable.
Insect repellent and sun hat
Protects against mosquitoes around waterways and provides sun protection during daytime walks.
Headlamp and small dry bag
Headlamp for dark cave passages and a dry bag to keep electronics safe during boat journeys.
