Arribes del Duero Natural Park

There is a really dope natural park on the northern border between Spain and Portugal, the Arribes del Duero Natural Park. You can see a really nice landscape, waterfalls and the river called Duero. There are a lot of hiking trails because this park is very big. If you search on the internet, you can find long routes or small ones that are only 2-3 hours long, like we did. When there is good weather and the water is a little bit warmer, you could swim in the pools down the waterfalls:

I can really recommend this one because there is absolutely nobody. You got the whole park for yourself. And besides all this nice landscape, the waterfalls and the nice hiking trails, you have incredible views because this is a mountain region where you can look down on the river more than 100 meters!
