Andros: Achla River Trekking to the Waterfall

Exploring Andros, one of Greece’s less traveled yet utterly charming islands, offers a wonderful mix of natural beauty and quiet authenticity. The Achla River Trek takes you through lush landscapes to the island’s only waterfall in the Cyclades, a spot that feels like stepping into a fairy tale. For just $73 per person, this 4-hour adventure combines light hiking, river exploration, and a refreshing swim — all guided by knowledgeable locals who know this area intimately.

Two things we really love about this experience are the opportunity to trek along a pristine river surrounded by trees and the chance to swim in the crystal waters at Gerolimni waterfall. The scenery is stunning — expect serene streams, thick greenery, and a waterfall that is both a visual and a sensory highlight. Plus, the fact that transportation is included for those staying in Chora makes this outing more convenient and relaxed.

It’s best suited for those who enjoy light adventure and are prepared with proper footwear and sun protection.
