Koh Rayang Nok (inc restaurant) - Thailand, July 2012 (sitios de interés)

Ko Rayang Nok is a similar distance (to Kham) to the south-west of Mak. The closest I've been is on the passing speedboat to Ko Kut, but the beach sure looks nice, similar to Kham's and like Kham you can day-visit for a small charge. There is also a resort there - looks to be flashpacker/lower midrange in standard from the website.
