The Tab Kak Hang Nak Nature Trail is northwest of Ao Nang close to beaches/resorts, a couple of kilometres north of Klong Muang Beach. It will take you through the jungle and up to a peak with a fantastic view over Ao Nang and more. A sign claims the hike to be 3.7 km but it feels like more. That's because the trail is almost all up. Thai trailblazers don't do switchbacks. No mosquitoes. There is a small ladder that needs to be climbed, but the trail is an easy one if you have decent shoes. Don't try this in flip-flops as the trail is rocky. with exposed roots and where it is not, it is certainly a mudslide when the ground is wet. At the trailhead they ask you to sign in with departure and return times.
