Sintra is best seen on foot. It's a short distance from Lisbon and the American International School. Both the North and the South of Portugal have their own special flavor. A trip to the Algarve will give you an idea of how many spend their lives dependent on the conditions of the sea. Fresh fish is available in any local restaurant and a visit to the local 'lota' is a must.
Fishermen auction their catch on a daily basis.
People are friendly and willing to show you what the area has to offer. Spend some time in small villages and try the local foods. You won't be disappointed.
