This is the best waterfall I've ever been.
There are area for beginner, advanced and even children. From water depth point of view of course!

Soak your feet into the crystal clear and cold water (Malaysia is pretty warm, as u know. So you can imagine what cold water can do.) Don't want to be wet yet? Sure, you may go for a jungle trekking. This waterfall located in a big forest reserve. You may go for a birding or just walk. after that, take a high jump from fallen tree into the chlorine free cold water! What a feeling!

However, if you prefer privacy, avoid to pay your visit during weekends especially school holidays. Like December to January. Just check with local authorities for details.

But please bare in mind, you have to hike a pretty up the hill and deep into the jungle to have the most beautiful scenery. Since during peak season, it can be very mess with litters, plastic bags. But so far, I haven't found any condom yet.
Ahha!
