An 8km long dirt road leads to this impressive beach, which is located at the northeastern part of the island. The valley behind Achla is the most important environmental area of Andros. The beach has small white pebbles and emerald waters. The small church of Agios Nikolaos stands out on one end of the beach. Just before you arrive, you will see the promontory of Gria on your left with the homonymous lighthouse.
