I was doing some multi-day hike around a crater lake with some friends; this involved a bit of walking along zig-zaggin hillside paths (sometimes they went through tunnels, too) with other groups of hikers above and behind and passing by. We had to find a hostel to stay at.
The next day we made it to a point at the top of the where there were train tracks, and maybe like a place to get ice cream. So that was nice.
