On day 4 we first went to the Svartifoss waterfall. Last year we already went to Argentina and went to and on the Perito Moreno Glacier, so we decided to skip Skaftafell, as we had to make choices since there's too much to see everywhere.
It took us approximately one hour to get to the waterfall. Once there it was peaceful to watch the water falling down. It was a nice start of the day.
Back on road 1 it seemed that there was a glacier that could easily be reached by car. The road to it however was very uncomfortable with big holes, but our Jimny kept on going without problems leaving normal cars behind. The parking was indeed very close to glacier Svinafelljokull.
