Why should you go there and how do you do it right?

Nestled in the karst landscape of Khao Nap Nam near Krabi Town, this atmospheric cave attracts visitors with its dramatic interior and one of the most impressive natural spectacles: thousands of bats swarm out of the cave entrance at dusk in a dense, swirling cloud. The cave itself is large and imposingly shaped, with remarkable stalactite formations along the interior path. Adding to its allure is its alleged connection to film history: remnants are said to be props from the production "Around the World in 80 Days" starring Jackie Chan and Steve Coogan.

Even the journey there is an experience. Most visitors arrive by small boat. A popular option is the short crossing from the nearby mangrove path for about 100 baht per person – it's worth negotiating a higher price. The surrounding mangrove landscape adds to the overall experience, and some visitors combine their cave visit with a longer boat tour of the region. A headlamp is recommended, especially for those venturing deeper into the cave.

The best time to visit to watch the bats emerge from their burrows is around 6 pm, when the spectacle reaches its peak. As it's an open-air and cave environment, comfortable footwear suitable for uneven terrain is recommended. Opening times are unconfirmed, so for those hoping to see the bats, arriving before sunset is the safest option.
