Parque Natural da Arrábida

Interesting park. It does not have dedicated entrance, it is simply the whole area of mountains and coast to the west from Setubal. As said in other reviews, there is a quarry inside, so a bit strange. I recommend the drive on the road through the hills with nice views (and spots to park for a while), even though the convent (monastery) is closed to public normally. But it can be very hot here. For example Lisbon had maybe even a bit colder temperature than it was here (39 C), while it was nice pleasant by the sea down there. Beware that the road from Setubal to access the beaches is one-way road during the day (not whole road, only from the first beach) and that it is problematic with parking, you have to go long way (or maybe pay, but I don't know how much), I would therefore recommend the more wild, with less accessories, beach, which is on the west, with the museum of oceanography. It was nice and less crowded there.
