Ko Phayam is the second largest Andaman Sea island off the coast of Ranong Province (Ko Chang, about 4 kms distant, is the largest). Ko Phayam has no roads suitable for automobiles, thus motorbikes are the chief means of transport. Tourists hire motorbikes at the pier and ride along the road to the resorts. There two major beaches/bays, i.e., Ao Yai and Ao Kao Kwai (Buffalo Bay). For those who want to get away from it all, Ko Phayam is reminiscent of what Ko Samui was like 30 years ago, before the airport and hotel developments.
Ao Yai is the largest bay on the west coast, about 3 km long and 300 m wide, with a white sand beach and a gentle swell from Andaman Sea. Stunning sunsets as well.
Ko Phayam is widely thought to be one of the most beautiful--and undiscovered--of Thailand's islands.
Ko Phayam is just over 30 km from Ranong, about 2 hours from the mainland's Phayam Pier by slow boat, 30-40 minutes by speed boat. The slow boat leaves at 09:30 and 14:00 from the mainland. 8:30 and 14:00 on the return journey. Speed boats depart at different and more frequent schedules (but not in low season).
From Bangkok you can take a bus (Mitrap Tours) which is leaving from Khaosan Road to Ranong for 544Baht (May 2013). The advantage with these busses is that you can make a reservation in advance. This bus is leaving at 7.00pm at the agency (the bus also stops at the south bus station). There are also some slightly cheapter busses running directly from the southern bus station, but you have to buy the tickets directly at the bus station.
Flight service from Bangkok to Ranong Airport and back three times a week via Happy Air 
Ferry Prices as of May 2013
Slow boat: 150 baht

Ferry Schedule as of Dec 2011
To get from the Ranong bus station to the Ko Phayam pier you can avoid tuk tuks and take a Songthaew instead. Therefore just walk to the main road and stop one. The costs are 15-20B per person.
No cars on this island. Motorbikes and scooters can be rented at Phayam Cottage Internet Shop near the main arrival ferry pier as well as many other places. The price is roughly 150-200 baht per day unless heavily booked. Gasoline costs 40-50 baht per litre. If you rent a motorbike don't drive it on the beach. There are rumours that you can get fined 5,000 baht because of fine print on the rental agreement.
Motorbike taxi drivers will be waiting for you as you step off the pier and can be found around the island, differentiated by their blue or red vests. Maps of the island near the pier are colour coded, showing you what the fixed price is to get to certain areas. 70 baht from the pier to Ao Yai. Ask your guesthouse to call you a taxi bike if you are at the quieter end of the island. The wait for a taxi to pass by can be longer than you wish to wait.
There are many beautiful beaches, some of them long like Ao Yai--the largest. The ferry pier area is vibrant with restaurants, a few Internet and other shops, and places to settle into a lounge chair or hammock and enjoy a cold drink or two.
Aow Yai (Long Beach) is the longest and busiest beach of the island with few bars located along it. You will find here some nice swells since it faces southwest and the Andaman Sea. Great for surfing, walking and meeting people.
Aow Kao Kwai (Buffalo Bay) in the northeast is a quieter beach. If you looking for getaway and relaxation - this is the place go be. Calm water here is ideal for swimming. There is a mangrove forest along the river on this beach - great place for kayaking.
