Snæfellsjökull National Park is a great place to go hiking in Iceland. It’s very close to Reykjavík, at the far end of Snæfellsnes peninsula, and it’s an area which definitely deserves a detailed exploration and there are many hikes you can do. Of course, the most prominent one is to the top of Snæfellsjökull, the 700,000 year old stratovolcano where Journey to the Center of the Earth by Jules Verne takes place.
