If you can leave earlier, the better. Otherwise you will be right there with all the tour buses.
You do not need tickets for any of this. Just pay for parking via the app or at a machine in the lot.
At Skogafoss, do not miss Kvernufoss which is just up the road from there. Beautiful and far fewer people. You do need to pay to park here so go inside to do that.
At Seljalandsfoss, facing it you will see a paved path to the left. Take that to get to Gljufrabui. There you need to hug the wall to get inside. People help each other and take turns. It’s beautiful in there but can get very crowded.
In Vik, both the Soup Company as well as Black Crust Pizza are excellent.
Don’t t forget about Yoda Cave which is very close to Reynisfjara. Btw it is paid parking at both of these now. At Reynisfjara you need to be extremely careful as there are many sneaker waves and people do get swept out to sea. There is a warning board to read and pay attention to what level warning it is. Do not go inside the cave. You will get trapped when the waves hit. Aldo ne er turn your back to the ocean and stay behind the wet line in the sand.
If you get short on time, skip Solheimajokul. Unless you do the actual glacier hike, you will not get very close to the glacier.
