Bor Tor is a small coastal village at the top of Phang Nga Bay. It is a bit closer to Krabi than Phuket, and is accessible by road from both locations. Limestone karsts sit close to the pier, right in the back of the mangroves.
There is a good concentration of caves or karst 'hongs' that can be accessed by sit-on-top kayaks, and the geology is amazing. There isn't as much wildlife as in Talin, but Bor Tor is rich in scenery.
