Bird WatchingThe best time of the year for bird watching is from Jan-Apr. Many rare birds are to be seen there: gurneys, finfoots, big-winged brown kingfishers, egrets, bitterns, and herons.
Cliff JumpingCliff jumping is fairly new to Ton Sai Bay. There are cliffs from 6-16 m that are ideal for cliff jumping due to the depth of water below. Organized tours can be found at Ton Sai, but be careful. Jumping can result in ruptured ears and back injuries.
There are many dive shops on Ton Sai Bay within walking distance of each other. They can organize all diving and accommodations. Expect to pay the same everywhere. A PADI open water course is 13,800 baht, with SSI being 900 baht less. There are a few different trips offered by Phi Phi dive operators, the typical trip is a two-tank local dive in the Phi Phi Marine Park which will run about 2,500 baht, or 2,000 baht if you bring your own gear. They also do 2-3 tank trips to the King Cruiser wreck with your follow-up dives at both Shark Point and Anemone Reef. This trip usually runs between 3,200-3,900 baht depending on the number of dives you do. Further away, Hin Daeng has some of the steepest drops in Thailand (60+ m) as well as being the place you are most likely to see manta rays and whale sharks, and can be a great dive trip, but it only runs if sea conditions are good.
Anemone Reef Between Ko Phi Phi and Phuket, a massive limestone pinnacle which soars 30 m from the seabed to just 4 m beneath the surface. The site is well known for the abundance of anemones that cling to every surface while attracting enormous schools of fish. Different types of fish to be seen include: tropicals, snappers, groupers and colorful clown fish, along with larger game-fish like tuna and barracuda as well as the occasional leopard shark.
Garang Heng Garang Heng is a small submerged reef just east of Phi Phi Leh. A healthy reef with anemones, soft corals, and an abundance of leopard sharks.
Hin Daeng and Hin Muang
From Ko Phi Phi, it is possible to dive Hin Daeng and Hin Muang, world-class dive sites, for around 5,500 baht. See Diving in Thailand
Hin Dot These submerged pinnacles, often called Chimney Rock, are located just to the south of Phi Phi Don. The formation drops to a depth of 30 m and has several coral shelves for exploration upon your gradual ascent. Nurse sharks can occasionally be found here.
Hin Pae This is a relatively shallow dive site, 10–15 m deep. Its shallow depth offers excellent snorkelling. Its soft and hard coral provide shelter for a rich variety of coral fish. Crabs, lobsters, angelfish, groupers, snappers, and surgeon fish are also residents of this area.
King Cruiser Wreck A popular site off Ko Phi Phi and Phuket is King Cruiser, remnants of a passenger ship which sunk in 1997 after it hit the Anemone Reef.
Ko Bida Nai Just up from Bida Nok is Bida Nai. Like its sister island, it is a good place for diving with good chance of black tip reef sharks sighting.
Ko Bida Nok Besides an abundance of pretty coral, this island is home to plentiful marine life including: leopard sharks, turtles and moray eels. This island is popular with divers.
Shark Point (Hin Bida) Shark Point is a marine sanctuary with a reef that made up of three pinnacles, the largest of which actually breaks the surface, appearing as a barren rock outcropping. The reef is home to a delightful abundance of tropical, colourful soft corals and vibrant sea fans that decorate the limestone pinnacles.
Shark Point Phuket Another submerged reef very close to Anemone Reef and often dived together with Anemone Reef and King Cruiser Wreck as part of a 3 dive package from Ko Phi Phi.
Wang Long This site is well known for its underwater cave systems and is only recommended for experienced divers. The caves tunnel into the rock face in two places and open out into a larger cave where surfacing is possible.
Loh Samah Bay The bay is popular for night-time divers. It has a sandy bottom with oysters and clams and patches of brain coral for nocturnal reef critters to hide amongst. There is a spectacular 15 m deep canyon just wide enough for single file swimming on the east side.
Sailing and cruising
Krabi has plenty of anchorages, usually deserted and all so beautiful. There are many charter sailing boats available and some even offer "join-in" day trips for two or more people. Phi Phi offers a variety of ways for sailing and cruising. Longtails can be hired for sunset tours and island excursions. They can be found on any beach.
There are two rocks within swimming distance of Long Beach known as "Shark Point" where harmless blacktip reef sharks can be seen. Many dive schools take snorkellers on their dive boats, but expect to see only a hint of the underwater marvels visible to scuba divers. The snorkelling off Bamboo and Mosquito Islands is quite good although the reefs are a long way below you at high tide. If you arrive on Bamboo Island in a longtail boat you will be asked to pay 200 baht/person to stay on the beach, or 400 baht/person to stay on the beach and further afield. Always ask for the ticket. With it, you do not have to pay 400 baht/person, just the 200 baht/person.
The Adventure ClubRuns "Shark Watch" snorkelling trips to Shark Point that guarantee a sighting of sharks. Paradise DivingWill point you in the right direction to the black tip reef shark's habitat metres from the sandy shore.
