Suwan Khuha Cave - Monkey Cave

The monkeys are the reason most people come, and they're also the reason some people leave early. A troop of macaques lives in and around this limestone cave in Takua Thung, and they're bold, quick and completely used to humans. Carry food openly and you'll lose it. Dangle a camera strap and you'll be negotiating. That's not a warning to put you off, just the deal you're accepting when you walk in.

Past that, it's a genuine working shrine inside a hill. Buddha images and religious objects sit among the rock formations, natural light comes down through gaps in the limestone, and the air inside stays noticeably cooler than outside, which matters a lot in the hot months. Thai worshippers use it properly, so dress and behave accordingly. The floors are uneven and the passages ask for a bit of scrambling in places, so wear shoes with grip rather than flip-flops.
