Portugal has a very diverse geography. The north coast has rougher seas with more sand, while in the south it's mostly calmer with cleaner oceans. Portugal has many national parks, and it also contains water parks where families can opt for an adventure holiday. Portugal has three international airports; Lisbon's stays in the city and the other is situated at Figueira. Both of these airports provide excellent facilities to passengers from UK, flying to Portugal is very simple even though the flights from UK just sometimes touch down in Portugal.
