Nathon is on the southwestern coast of Ko Samui and hosts the port with the ferry to Surat Thani.
Nathon is connected via the Ko Samui ring road with the other villages on the island. Ferries from Surat and Ko Tao arrive here.
From the pier there are brown songthaews which go to Bophut/Chaweng to the leftand also in the opposite direction to Lamai. These are local taxis and cost 50 baht for a local trip to Bophut. To Lamai in the other direction will cost B70. There are also many taxis at the pier and you negotiate a price to where you want to go.
With the songteows, they apparently go to Chaweng in one direction and Lamai in the other, but not from Chaweng to Lamai or vice versa (although several were seen from the taxi!) Taxi to Lamai from Bophut is B400.
Nathon is famous for its very picture-perfect sunsets. Most tourists come specifically to enjoy the spectacular views and the quaint little shops and restaurants that line the ocean front. The town itself is quite picturesque and is fast becoming a known shopping and dining destination.
Best Mountain View is the place to be if you really want to get an eyeful of the grand views from 467 feet. It's sightseeing on a whole new level. It's quite an arduous trek to Best Mountain View but it is totally worth it.
Nathon Walking Street on every Saturday. Many local foods and local products.
From the pier, get a boat to Surat Thani for B400. The boat arrives at Donsak Pier, and there is then a bus to the city. Busfare is included in the ticket.
There is a ferry at 1pm. There are also others, and the timetable is online.
