If you want to go to Portugal but can't decide between Lisbon or Porto, one of the best ways to make a choice ... a haven of hiking, beaches, mountains, and wildlife experiences.

The best way to explore Lisbon is by foot ... If your teens want more than surfing, you can visit Lisbon beaches such as Praia de Carcavelos, Praia do Tamariz, and Praia das Avencas.
