The best waterfalls in Kedah

I finally made it to Langkawi over a long holiday. I'm not young anymore and had never been, which I found a bit embarrassing. The news had been saying hotel occupancy on the island was down, so I assumed it would be quiet. It wasn't. Every attraction we went to was packed.

So I went looking for something smaller, and that's how I ended up at Temurun Waterfall in the northwest corner of the island. It's far from the main shopping area and the popular beaches, which I think is why it felt so much emptier. A few other people were there, but it never got crowded. The mood was relaxed, and I didn't feel like I was queuing for anything.

How long is the walk to Temurun Waterfall?
