Four Island Tour (Ao Nang) - taking in the group of islands closest to the coast – the ones that can be seen on the horizon from the beach. The four islands are Koh Poda, Koh Gai (Chicken Island), Koh Tub and Koh Mor; and the tour also stops off at the beautiful Phra Nang Cave Beach on the Railay peninsula. This beach, inaccessible by road, is considered to be one of the most beautiful strips of sand in the world.Koh Poda is famous for its white beaches and turquoise water; the huge rock in front of it (pictured above) has been featured on countless postcards, screeensavers and tourist brochures, so don’t miss the opportunity to snap your own photo memory here. The cruise around the “head” of Chicken Island, with the odd rocky outcrop that earned it its name also makes a good photo op. Fun fact: Chicken Island is really called “Axe Island” or Koh Hua Gwan; it was dubbed “that chicken island” by Krabi’s first tourists and the nickname stuck. At low tide, the boat will stop between Chicken Island with the two tiny islands of Koh Mor and Koh Tub, where you will have the opportunity to walk along the sweeping three-pronged sandbar that links the three together.There will also be a couple of stops at open water snorkeling sites, which could be near Koh Yawasam, a rocky outcrop with fairly intact coral reefs and decent marine life, or at the rear of Chicken Island, depending on the day. Snorkeling here is average due to years of heavy boat traffic. Itinerary order varies throughout the month, so that the sandbar can be reached at low tide (at high tide it is barely visible) and will include a picnic lunch (or BBQ dinner) on one of the islands or beaches.
