How to get there Koh Samui - Express Boats Songerm Co. express boats to Koh Pha-Ngan leave from the Na Thon pier on Koh Sami every day November to May at 10 a.m. and 3 p.m., the remainder of the year 10 a.m. and 4 p.m..  The trip takes 50 minutes and costs Baht 50 one way.  Boats back to Samui leave Pha-Ngan's Thong Sala pier at 6.15 and 1 p.m. daily; in this direction the fare is Baht 60. Koh Samui - Other Boats A small boat goes direct from Samui's Bang Rak (near Bo Phut village) to Hat Rin on Ko Pha-Ngan for Baht 50 to Baht 60 (depending on who's got the concession, the boat sometimes leaves from Bo Phut instead).  This boat departs Bang Rak/Bo Phut just about every day at 10.30 a.m. and 3.30 p.m., depending on the weather and number of prospective passengers, and takes 40 to 45 minutes to reach the bay at Hat Rin.  In the reverse direction it usually leaves at 9.30 a.m. and 2.30 p.m. and takes 30 to 40 minutes. More From January to September there is also one boat a day from Hat Mae Nam on Samui to Ao Thong Nai Pan on Pha-Ngan, with a stop at Hat Rin.  The fares are Baht 120 and Baht 60 respectively and the boat usually leaves Mae Nai Pan around 8 a.m..  A new company called Rossarin Tour has 35-passenger speed boats that go between Samui's Hat Mae Nam and Thong Sala for Baht 150; this boat only takes about half an hour to reach Thong Sala. Surat Thani - Night Ferry  Your can also take a slow might ferry direct to Pha-Ngan from the Ban Don pier in Surat.  It leaves nightly at 11 p.m., takes 61/2 hours to arrive at Thong Sala, and coasts Baht 100 on the upper deck, Baht 60 on the lower.  As with the night ferry to Samui, don't leave your bags unattended on the boat there have been several reports of theft. Surat Thani - Other Boats  A couple of years ago a fast jet boat and another express boat competed with Songserm for about a year, but Songserm immediately dropped its fares to a loss level and ran them out of business.  With increasing tourism in the islands, it's only a matter of time before someone else steps in and gives Songserm a run for its money.
