The Andaman Sea - Most of the diving off the western flank of the isthmus is based around the southern beach resorts of Phuket, Krabi, and Ko Phi Phi. The three-dives-in-a-day outings include the triad of Shark Point, Anemone Reef, and the Ko Phi Phi National Marine Park and prove most popular. Teeming with schools of reef fish in every stripe and hue, “Shark Point” is the most often visited site in the area and was named after the leopard sharks often spotted on the sea floor.
The Similan Islands - consistently ranked as one of the world’s top 10 dive sites, this nine islands archipelago is located some 59 miles northwest of Phuket and have been a national marine park since the mid-80s. Even the names of the different dive sites conjure up mental pictures of underwater exotica, such as Elephant Rock, Stonehenge, Coral Gardens/Hobbit land, Christmas Point, and Fantasia Reef.
Ko Tao Island - is the nucleus of some of the most dazzling sites in the Gulf of Thailand. Because of the number of secluded bays and shallow reefs, more rookie divers get certified here than anywhere else in Southeast Asia. For more experienced divers, Ko Tao boasts the Chumphon Pinnacles. Often referred to as the most spectacular site in the Gulf, this collection of enormous boulders is the perfect place to spot large schools of Great Barracuda, as well as mackerel, tuna, and the world’s biggest fish , the whale shark – these gentle giants can be as big as a city bus. Visibility is superb during the cool season, and the depths vary from 39 to 118 feet.
The north of Thailand - is the undisputed bastion of nature. Not only are the forests full of a wild assortment of birds, animals, and orchids, they are also perfumed by sweet mountain breezes and renewed by freshwater streams. The mountains are also home to a number of exotic hill tribes, where visitors can stay overnight in their villages. Trekking expeditions, which usually range from one to three days, include other perks. Elephant rides, bamboo rafting, visits to hot springs and swimming in spring-fed pools beneath gushing waterfalls are the rejuvenating interludes of many itineraries.
