Views from Sveinstindur are out of this World. I'm so glad I made it here, quite a bit into Icelandic Highlands.
Getting there: After driving F208 and then F235 roads, it's just about negotiating the last ~400 vertical meters from parking to the Sveinstindur summit, which will take you close to an hour. Or, closer to 30 minutes in case you don't get up early enough, which was just my case. ;-)
