February: Visiting a frozen waterfall in the Highlands of #Iceland with a guide, and he led one of our party across the knee-deep snow to a safe viewpoint. I wasn't confident enough to follow them!
Hrafnabjargafoss is only really accessible in summer, because it is located on a highland road that is closed to the public in the winter months. Even in summer, it can only be reached safely in a 4WD vehicle.
