I can't even pretend to pronounce the name of this canyon, but from the minute we booked our plane tickets, this was at the top of my list. I obviously had to see it from both the top and inside, but when we got inside the canyon, the paths along the side were flooded. I took off my shoes and socks and attempted to cross the river flowing through, but the water was too deep and absolutely frigid. I've never felt water so cold. It felt like knives.
And that, in a nutshell, is the coldest thing I did in Iceland.
