Here is another video of beautiful Nai Yang beach this is an older video and was taken late August 2007 during the low season, during the low season you almost have the beach to yourself. This time of year you can get some pretty good surf and winds, excellent for kite surfing. The little seaside restaurants are fun to stop at and you can really get a good bargain for some good Thai seafood.
Nai Yang is about 45 min drive from my location in Kata beach, but the trip is well worth it once you arrive, I try to get up here about twice a month. If you're coming from the airport it's only minutes away and you can find some pretty good accommodation depending upon how much you want to spend.
