It's possible to get on a real roadtrip on the island. It's called the golden circle.
You can hire a 4x4 or go with an orginasation. We actually get the bus in Reykjavik and go in the direction of landmannalaugar. We stepped out of the bus between 2 stops.
Weather is changing every minute in Iceland. My trip was in the beginning of July but we did have a night sleeping at -7 celcius.
This was a picture of the morning we climbed the Vulcano Hekla in Iceland.
Our roadtrip was on foot 170km for 10 days and this was the start.
26km 11 hours 1175 m up and down.
