Portugal has a very diverse geography. The north shore has more demanding seas with more sand, whereas in the south it's mostly calmer with cleaner waters. Portugal has several national parks, and in addition it contains water parks where families can opt for an adventure holiday. Portugal has three international airports; Lisbon's remains in town and the other one is situated at Figueira. Both these airports offer exceptional facilities to passengers out of UK, flying to Portugal is very easy though the flights from UK just occasionally touch down in Portugal.
