More ways to explore the area's outdoor wonders
A short drive down a sun-baked coast opens onto Achla: a wide sweep of pebbled sand, a shallow river that keeps the shore green through summer, and the white cone of Gria lighthouse watching the Aegean swell. The river threads fresh water across the beach, pushing cool currents into the sea and giving the shoreline an uncommon sense of motion for a Cycladic beach. Plane trees shade the upper strand, their trunks and leaves flicking like silent sentries.

Conservation
The Achla river sustains riparian vegetation year-round; visitors should avoid altering the river mouth, take all trash with them, and respect shade trees to protect the fragile coastal habitat.
Reserve your spot on the Achla beach and Gria lighthouse tour today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Sun protection is non-negotiable
Bring high-SPF sunscreen, a wide-brim hat, and UV sunglasses—the Aegean sun is strong and there’s little permanent shade on the shore.
Footwear for pebbles and rocks
Wear water shoes or sturdy sandals for the beach and short rocky approaches to the lighthouse to protect feet from hot pebbles and sharp rock.
Watch river currents
The Achla river creates shallow pools but also channels that can change with tides and wind—supervise children and weaker swimmers.
Leave no trace on riparian zones
Keep to paths around the river mouth and avoid trampling plane tree root zones to protect the freshwater-fed habitat.
Swimwear and quick-dry towel
For swimming in the river-fed pools and sea; quicker drying makes transition back to the vehicle easier.
