Island hopping tours allow visitors to see the best of Krabi, its glittering white-sand beaches and rainforests within a day or two. The four iconic islands in Krabi for day trips are Koh Poda, Koh Hong or Chicken Island, Phra Nang Cave, and Tup Island. They are best explored from November to March by cruises and speed boats from Ao Nang Bay. One can enjoy swimming, snorkelling, island lunches and sunsets during the tour.
