We are going for a hike in Belas, just in the outskirts of Lisbon, 20 min away by train.
An urban area located next to small hills which we are going to explore.
We are going to walk for about 10 km; partially in the city, partially in the woods.
Close to the end, we are also going to visit the gardens of a 19th century palace, which have been recently renovated.
Bring some food, we are going to make a picnic there.
Then we will take the train back to Lisbon. I am expecting to be back in Rossio train station around 7 pm.
