This is the main beach of Ko Lanta. It's a few km long and has dozens of resorts and restaurants alongside but it isn't crowded! You can spot people here and there but you'll have a lot of space for yourself. Water is clear, sometimes gets wavy and the sand is soft.
One of the most beautiful beaches I've ever seen! It's also a fun people watching place when the cruise ships flood the island. And on rainy days, the bar provides shelter with good drinks and conversation with a happy environment. We recommend Aaron, the bartender, for info on where to go and what to see that may be off the beaten path.
