I like this beach. It's not far from the Pier, but there are fewer people than on the next one. Sun beds for 100 baht per day. But drinks are 4 times more expensive than everywhere else. But there is a 7/11 nearby - you can buy there in advance.
I expected more from this beach on Koh Lan. So, you can visit once. The water is clean, but in 3 hours the water has gone a lot. It is cooler by 2C than in Pattaya and it is noticeable. It's crowded, there are a lot of Chinese tourists. They are brought in organized groups. We took the last 2 sun beds under an umbrella, although there were three of us. There is no shower, the toilet is just above the restaurants for a fee, in extremely terrible condition, there is no point even explaining.
