The Verdon Gorge, in south-eastern France, is a river canyon that is often considered to be one of Europe's most beautiful. It is about 25 kilometres long and up to 700 metres deep. It's now on my bucket list.
The Goðafoss (Waterfall of the Gods) is one of the most spectacular waterfalls in Iceland. It is located in the Mývatn district of North-Central Iceland at the beginning of the Sprengisandur highland road.
