We had spent a quiet New Years Eve in the parking lot of the Polylimnio Waterfalls. There was one other van there, also with a Germany licence plate.
On the first day of 2022, we were on the trail by 10:00am to the waterfalls. I hadn't actually done a lot of research, other than knowing that the trail was about 3 kms (1.9 miles) long, and that there were a series of different waterfalls.
