1. Alvao Natural Park

Though small in size, Alvao Natural Park is a top choice for travelers who enjoy both physical pursuits and time to relax. There are two distinctive and different ecosystems that make Alvao so special.

The Upper Zone is more mountainous, perfect if you like hiking, biking, and exploring the rocky cliffs and difficult paths. It leads down to the Bazal Zone, which opens up to a stunning waterfall and more of a ground area for you to enjoy the silence and take in the beauty of your surroundings.

2. Douro International Natural Park

Douro is usually a part of any extensive trip to Portugal and stands high among other national parks. Located on the border with Spain, it marks the path and waterway between the two neighboring countries, allowing you sights of the most stunning landscapes - rocky cliffs and ravines cutting through the Douro River and the greenery above it all.

The international was added to its name since it is so close to another country, and while it belongs to northeast Portugal, you can easily access it from Spain, as well!

3. Ria Formosa National Park

Located in the South of Portugal, the region of Algarve, Ria Formosa National Park is perfect for beach-lovers and those who feel for the beautiful, unique birds.
