If you are looking for a peaceful beach on Koh Phangan, I highly recommend Wai Narm Beach. This beach stands out for its authenticity; it boasts a smooth shoreline with fine, soft sand that's perfect for a leisurely stroll. The water here is also incredibly clear, making it an ideal spot for swimming. Wai Narm Beach primarily attracts those in search of tranquility, which is why it has become a popular location for yoga and meditation retreats.
