1. International Douro Natural Park
This park is located on the border between Portugal and Spain, and in fact, is the natural border of both countries, with the river passing through it marking just that, and therefore it is considered an international park. The river passes through cliffs that have eroded for thousands of years, no matter what side you look at, they are beautiful and impressive. On both banks of the river, there is green vegetation that protrudes against the gray rocks and gives life to the area.
2. Montesinho Natural Park
Montesinho Natural Park is one of the largest parks in Portugal and one of the most diverse in terms of animals, vegetation and landscapes. During a walk in the park, you will see hills, valleys, streams, lakes and even tangled forests that seem to have no end. Most of the trails reach the top of the mountain after which the park is named, and from above you can see an impressive view all around. It is very possible that you will encounter carnivores such as a lynx or even a wolf, even though they tend not to approach people.
3. Northern Littoral Natural Park
This park is located in northwestern Portugal and has an amazing view facing the Atlantic Ocean.

This is a wild but peaceful place that has barely been touched by a human hand except for a few areas where there are water activities, vacation homes, and beach recreation, perfect for those looking to relax and free themselves of modern life for a few days.
