In the park are two islands of outstanding yet contrasting beauty. These islands have become the symbol of the perfect tropical island. There are also extensive mainland beaches and over 80 lesser islands. The boat ride to Phi Phi Lea and Phi Phi Don from Krabi Town's Chao Fah Bridge Pier is a pleasant journey. The perfect season for these enjoyable rides is during November to April. The trip can take between an hour and a quarter to three hours depending on the size of the boat. During the rest of the year, the Andaman Sea can be choppy and the weather can cause havoc with travel plans while at sea.
