We walked the Volakias route to Agia Roumeli in about 13 hours, starting from Xyloscalo at 6am and arriving at AR at 7pm. Optimistically I thought we would get to AR in time for the last ferry to Sougia, where we had the studio (we had driven to Xyloscalo and left the car there in the morning), but weather forecast was wrong that day and there were a few showers before and during the Psiristra crossing which slowed us down. There are a couple of scrambling sections, the first one when you traverse the large gully between the two Volakias summits (pics 12 to 15 in my album) and the second one is at the end of the Psiristra section when you have to descend a steep slope and reach a saddle (pic 27).

, you will find other photos and a description of the route plus a GPS track. I take this chance to thank Simon once more for the ideas and the resources he and other contributors share there.
