A pre-Christmas Sunday hike of about 10 km, +/-400 m and around 4 hours on the northern slopes of Parnassos, starting from the traditional village of Tithorea next to the Velitsa gorge. The route crosses dense forest, cool streams and open viewpoints on the way to Dipotama, the spot where two rivers meet in a green ravine. As every year, at the end of the trail the group decorates a fir tree in the forest with eco-friendly ornaments for the forest animals (fruit, vegetables and natural materials gathered along the way): bring a piece of string to hang them. The day ends at a traditional raki house in the area with hot food, tsipouro from their own distillery and a fireplace. The meal is not included; after booking, every participant (not only the person who booked) must choose a main course on the organizer's menu form: https://form.jotform.com/262711434333349. Suitable for beginners in very good physical shape. Coach from the Agios Antonios metro station in Peristeri at about 08:30 (approximate), back at about 21:00 (approximate). The €39 includes the coach (driver's meal, fuel and tolls), mountain guides who graduated from a guide school and are trained in first aid, guides' expenses, a first-aid kit, civil liability insurance, photos and 24% VAT. Online booking closes on 12 December. Be at the meeting point 10 minutes early: the coach leaves on time. The order of the programme may change with the weather or other unforeseen conditions. Bring a windbreaker, a waterproof, a backpack, a personal first-aid kit, at least 1.5 L of water, a light snack, hiking boots and a second set of clothes and shoes (equipment list: https://activetravelersingreece.com/equipment/; grading: https://activetravelersingreece.com/difficulty-level/).
