There are vendors here as on any other beach and there are also a couple of restaurants to fulfill your needs. It's very green and very lush. The stop at Hat Naiharn is a part of a route in the southern part of the island. Riding a Honda Shadow through this scenery is something everybody should experience at least once in their lives. You can't really find use for all the acceleration and speed of a CBR on Phuket anyway.
Moderate speed is the key to a day on the bike.
Rawai is the destination next week. This is the place to go when you're interested in transportation to some of the numerous uninhabited islands that surrounds Phuket.
