When the tide is right, places like Monkey Bay are just about as accessible as physics allows. The coral is just below the surface and brightly coloured fish dart here and there, inches from your mask. Hin Klang is in the middle of the sea, though it isn't nearly as deep as expected; you don't have to impersonate an island native on the hunt to enjoy the views - floating on the surface is fine. Phi Phi Lei has a few more snorkelling locations, as does Phi Phi Don, Bamboo Island, the list goes on.

Tour operators will supply equipment - i.e., fins and a mask - if you book a package trip, or you can rent them from dive operators if you choose to strike out on your own via foot or longtail boat. The serious may want to bring their own gear, or inspect before booking, as quality and available sizes will vary between shops.

It is a scandalously known location for Leonardo Di Caprio's film "The Beach", as this island has a lot to offer.
The island is made up of towering limestone cliffs which form 3 main bays. The 3 main bays are:

1.Pileh Bay

2.Loh Samah Bay

3.Maya Bay

Pi Leh Bay

This is a small lagoon-like bay. Entrance of the bay is only at low tide although the far end of the bay drops off to form a small tarn. There is a small beach in the corner.

This bay is situated in the west coast opposite to the Maya Bay. Similar to Maya Bay it has 100m plumb cliffs rising from the water. Other than the afternoons this bay is fully in shade all the time.

This long thin bay is pretty shallow and is only accessible to speedboats and longtails, it does not dry out at low tide and there is a very small beach right at the back that you can just glimpse if you're passing. It is very beautiful and excellent for swimming. Entrance of the bay has excellent snorkeling opportunities.

Loh Samah Bay

The Phi Phi Island of Phi Phi Lei houses one of Thailand's most beautiful beaches: Loh Samah Beach. This is one amongst the stunning beaches in Thailand, and this is also one of the most beautiful beaches in the world. Even though the island is unpopulated, it is one of the most breathtaking to take a vacation.

This bay is located in the south side of Phi Phi Ley Island. This bay gives a nice dive as the mouth of the bay is crowned by a small island. It also has a small beach which is a nice spot to stop for a picnic. People access the back end of Maya Bay as it has a hole in the east wall of the bay.

Maya Bay

This is a stunning bay that's protected by 100-metre high cliffs on three sides. Inside the bay are many beaches, most are small and some only subsist at low tide. The main one is around 200m long with silky soft white sand, underwater colorful coral and fish live in exceptionally clear water; the whole bay is one big reef.

This bay is famous as the "The Beach" was settled here. It is not enclosed as it seems in the film however this does not diminish the splendor of this bay. One main beach and two minor beaches are located in this bay.

This bay became the chief tourist attraction of Phi Phi since 'The Beach' was filmed here in 1999. This bay was famous even before the film was shot here, but now it is even more famous after the film because it is known to everyone who hasn’t even heard of Phi Phi but now is aware of Maya Bay.

Maya Bay can be visited only from November to April, because the large waves make the doorway hazardous for boats during the other months of the year. On any given day there will be 30+ speedboats and longtail boats on the beach, with large ferry boats carrying hundreds of snorkelers and sightseers moored in deeper water. It is stunning; it is not secluded thousands of people visit each day. To avoid crowd you can visit early in the morning or after 5pm.

200 baht is been collected per person as the main beach of this bay is being patrolled by the National Marine Park rangers.
