Hi, I'm Helena, I'm portuguese, born and living in Porto district!
And you say... wow, good, Helena is going to tell us a lot about Porto.
Well, not this time. I'm here just to say a thing or two about Alentejo.
Alentejo is not a place to do things. It's quite the opposite. Alentejo is a place to stay. A place to feel. A place where you don't rush to experiment, do, visit... oh no, it's a place where you just don't rush taking many pics for future memories. You don't need that. The region stays inside you, in your soul. You will have time enough, (because you are not rushing) to see the wild animal life (the partridge are lovely, but maily in Spring, when they are looking to be a couple, and so are the hares, always running from one side to the other). And don't forget to look at the sky. In the night. A beautiful sky! (There was a planetarium here, not sure if it still exists, it's the better place in Portugal to look at the sky! Looking at the sky, I know, it's not adventurous, I think noone ever that was in Portugal spoke about the sky, but well, anyway...)
Alentejo is a big region, from the ocean to the borders with Spain (West to East) and covering a lot of land from North to South. I like the beaches, but for me they are very windy. They are lovely, Porto Covo, Azambujeira, etc, but to me Alentejo is more about the interior. My favourite place is Minas de São Domingos.
Wow, what to do at Minas de São Domingos? Well... nothing. If you have a car, visit "Pulo do Lobo". Besides that, just go to the river beach, very lovely. Eat at the local restaurant (there are only two) AND accept the appetizers (not a very common thing to advise to people coming to Portugal, but trust me, the cheese is from another world!!!) And... Well there are a couple of other thing to do, but they are kind of not exactly legal, I'll send a pm.
Have a nice time, no matters if you visit Alentejo or not, and if you need some insight, I'm at your disposal!
