Gunung Mulu Malaysia, East Malaysia (Sarawak)

For decades, scientists have studied this shining example of karst topography; it perfectly showcases the sinkholes and caves that exist in such terrain. But aside from science, it’s a sight unlike any other. Surrounded by lush green vegetation, tall rock formations suddenly emerge from the trees.

Getting there is half the fun – this is not for the faint-hearted. Those wanting to see the Pinnacles of Gunung Mulu embark on a multi-day trek up the mountain, carrying all the food and water they need for the journey.

The climb to the Pinnacles is tough, but it's just the beginning of the adventure. At the base of the rock formations, adventurers stay overnight and prepare for the climb the next day. There are a series of unprotected ladders, metal beams, and ropes to assist climbers on their way to the top, but it’s a dangerous journey to the lookout. If you’re not intimidated by a bit of thrill and danger, this will be one of the most amazing experiences of your trip to Malaysia.
