If you’re looking for a unique experience on the Greek island of Andros, the Achla River trek to the Gerolimni Waterfall offers a perfect blend of nature, adventure, and a splash of serenity. This guided tour takes you along the only waterfall in the Cyclades, and it’s easy to see why many travelers rate it a solid 5 out of 5. From the moment you start the short hike to the river’s edge, to the refreshing swim beneath the cascading water, the journey promises a memorable day away from crowded beaches and into the island’s lush heart.
What really catches my eye about this experience is how it combines accessible adventure with genuine natural beauty. The guides, like Bill and James, go beyond merely leading; they share stories, ensure safety, and take care to make everyone, including children, feel comfortable. Another standout? The chance to swim in the crystal-clear waters of the Gerolimni Waterfall, which many reviews highlight as the ‘incredible treat’ at the end of a manageable trek.
The one thing to consider before booking?
