Into the Frozen Abyss
I think Geysir's famed Gulfoss Waterfall is even more spectacular in the winter when the frigid Icelandic temperatures and blustery winds transform the waterfall into a jaw-dropping frozen wonderland.
Gulfoss Waterfall was the very first thing my husband and I went to see on our January trip to Iceland, and I knew as soon as I laid eyes on it that this wouldn't be a trip I'd soon forget. We managed to be at the waterfall just as the sun was popping above the horizon around 10:00 a.m. and we had the whole place to explore by ourselves before other tourists showed up.
On any trip to Iceland, definitely take the time to see the famed Gulfoss Waterfall, which I think is even more dramatic and beautiful if you can see it in the winter.
