Portugal, whose borders are drawn with Spain in the south and north, is isolated from its neighbors both geographically and culturally. Having a rich and unique culture, Portugal welcomes its visitors with its vibrant cities and beautiful countryside. The transportation network is very convenient and fast. The train network is faster than the buses, but is less frequent and expensive. The most advanced metro networks are located in the cities of Lisbon and Port. A final note, Portugal is not suitable for hitchhiking.
