Portugal stands on the southwest tip of Europe, surrounded by Spain and the Atlantic Ocean. The north is lusher, the south more arid. Both regions are moderately mountainous. There is plenty of Portugal's maritime heritage remaining, particularly in its capital, Lisbon, and the second city, Porto. Both are popular visitor attractions ' a pair of charming historic cities standing alongside major rivers near the sea. The Algarve region on the south coast is also a major tourist seaside destination. If you have a hire car in Portugal you'll find that its good roads and light traffic generally make it one of the best driving environments in Europe.
