To be fair we didn't actually made it up there. It's steep, it was all snowed over and very icy. We tried going as far as we could but we made it about halfway up not even sure if were still following the path. Our crampons weren't enough to make it up any further, we kept sliding back down. It was still a great sight and we'll return for this one in better conditions.
Búðakirkja is very close, worth a visit!
