During the winter months, GEO bicycling and more will be situated in Athens, organising bicycle tours in Parnitha and Tatoi. Parnitha is a densely forested mountain range north of Athens, with an elevation of about 1,400 m. that makes it an ideal destination for MTB and downhill. Tatoi is the southeast-facing slope of Mount Parnitha and the former summer estate of the Greek royal family (the region belongs nowadays to the Greek state). It is a fairy-tale destination only 27 km. away from Athens, where you can enjoy a ride or a walk inside the pine-tree forest and around the abandoned stone buildings. Both locations are designated as national parks and protected habitats for many unique Greek flora and fauna species.
