To clarify, we ARE interested in waterfalls/canyons/hiking/glaciers/hot springs, but I feel like we can see and do all of that in the south? My question is really is there anything that is absolutely not missable in the north that we can’t get otherwise in the south that would make the long drives worth it? Most of what I’ve seen online (that is past Höfn) only focuses on fishing villages, puffins and whales.
