From Dionysos to Rapentosa

A route along quiet dirt roads and rideable trails, crossing the “Kibetoúi” stream, visiting the small wetland and the Rapentosa waterfall—the tallest waterfall in Attica—all just a breath away from the northern suburbs of Athens.

INTRODUCTION

The route unfolds along the northern foothills of Mount Penteli, specifically on the small and little-known Dionysovouni, whose highest peak reaches 651m. The mountain’s gentle slopes were once covered in dense pine forest, which shared the fate of many woodlands lying too close to the city of Athens. Three major fires between 1996 and 2009 devastated the area, leaving behind only pockets of vegetation that now struggle to multiply and restore the landscape’s former glory. The scenery, however, changes dramatically at the eastern end of the route, where around the Rapentosa dam and waterfall, lush vegetation thrives. Water flows year-round, creating a small wetland—a haven for a variety of birds, reptiles, and amphibians—while the waterfall itself remains one of Attica’s hidden gems (though for how long, no one knows).

ROUTE DESCRIPTION

The starting point lies at the northeastern edge of Dionysos. The route first crosses Dionysovouni, descending via smooth dirt roads to the Rapentosa wetland. Here begins the most adventurous and captivating section: a well-marked downhill trail leads to the dam, and from there, following the riverbed for about 1 km—sometimes riding, sometimes pushing the bike—we reach the Rapentosa waterfall. The journey concludes with a gentle 9 km climb on compact dirt and paved roads, leading back to the starting point.

Rapentosa's Waterfall

The tallest waterfall in Attica, standing at 15m. It’s an ideal spot for a break, rest, or even a refreshing shower during the summer months. To reach it, follow the stream upstream from the point where the dirt road meets the ravine.

\
Rapentosa Wetland

Until 2004, the Rapentosa area was a small valley north of mount Penteli. That year, a dam was built by the Athens Water Supply and Sewerage Company (EYDAP) to control the floods that plagued Marathon’s wider region. The construction created a reservoir holding 1,265,000 cubic meters of water. Today, it is one of Attica’s few wetlands, playing a crucial role in preserving the area’s rich birdlife.
