Koh Lanta Noi
Lanta Noi has no tourist facilities as such but is well worth a visit. Hire a motorbike and catch the ferry or longtail from Saladan Pier, there's a few circular roads, all well covered that will take you around the island to see the local way of life. There are a few local restaurants along the way so you can stop for some fried rice, pick up a map before you go from one of the tourist offices on Lanta Noi, and drive carefully!
