With national parks scattered from north to south and from the Canary Islands to the Balearics, you won't have to travel too far to get into the wilds of nature.
Teide National Park, on the Canary Island of Tenerife, is frequently the most visited national park in Europe, with millions attracted by its other-worldly volcanic landscapes.
While the Picos de Europa offer the tantalizing promise of a glimpse of the Cantabrian brown bear and Monfragüe is a bird watchers' paradise.
Or head to the sand dunes of Doñana or the forests of Cabañeros.
You just have to choose which one to discover first.
