Get picked up from your hotel in Krabi by a songthaew, an adapted Thai-style pickup truck. Enjoy a scenic drive through rural villages to Baan Nai Nang, on the rugged coastline of Ao Luk Noi in the north of Krabi. Meet the crew at Wang Toh Tao Pier, where you will undergo a short health check-up before starting the longtail boat ride to Khao Karos Bay. Cruise by traditional longtail boat with a knowledgeable local captain and guide. Pass through a maze of mangroves surrounded by natural waterways connected to the Andaman Sea. Admire the steep, bizarrely shaped rock formations that protrude from the mangrove forests.  It's now time to change to a smaller and more maneuverable kayak, which lets you enter the waterways leading into a very narrow canyon, flanked by towering rock cliffs on both sides. Visit the ‘Ghost Mountain’ in the death valley, a limestone rock that features a spooky face.  Continue to Cave Man Window, a cave that can only be accessed by boat. Inside the cave are several short ladders, which you can climb up to reach a ledge that offers fantastic views across the bay. On the way to Makham Bay in the southern tip of the Garos mountain range, you will see some 3000 to 5000-year-old wall paintings. At midday, enjoy a Thai style lunch at the hidden beach of Hat Makham. Here you can take a refreshing dip in the water and relax under the shade of the trees with a fascinating view over the Andaman Sea and surrounding islands. The last highlight is the lagoon of Lae Nai, where you can take photos and go swimming. Finally head back to the pier, where the driver will bring you safely back to your hotel.
