Lonely Beach, otherwise known as
Hat Tha Nam, has more budge accommodation, but there are many bars here so it could be quite
noisy with loud music booming until the wee hours of the morning. The different bars seem to rotate in hosting parties different days of the week. If you don't mind the noise, you could stay at
Sea Flower Resort.
It's quite good during the day for swimming though, as the water is quite shallow far into the ocean - the north end of it has warning signs for riptides though. Other than part of the shoreline lined with small rocks, the beach has fairly soft sand.
