Hat Laem Sala, a sandy beach flanked on three sides by dry limestone hills and casuarinas, has a small visitors centre, a restaurant, bungalows and a camping area. The trail to Tham Phraya Nakhon starts here. Boats to the beach, which take up to 10 people, can be hired from Bang Pu. You can also reach the beach from Bang Pu via a steep trail (20 minutes' walk).
