Cascais is located in the Lisbon region. Portugal’s capital Lisbon is about 16 miles from Cascais (as the crow flies). The coastal city is a medium-sized town in the Lisbon region of Portugal with a population of about 36,436 people and is one of the largest towns in Portugal.

Once a picturesque fishing village, today a colourful and pretty holiday resort with elegant pedestrian zones, fashionable shops, restaurants and bars. The coast around Cascais offers a variety of beaches from family friendly with calm waters and soft sand to wild and rough surf beaches.

The coastal town is surrounded by popular beaches such as Guincho Beach in the west and the lush Sintra Mountains in the north. A part of the coast is rocky and attracts tourists for its seascape and other natural attractions such as Boca do Inferno.

It will also be a popular destination for golfers with more than 10 golf courses nearby. Surfing, sailing, windsurfing and kitesurfing are also popular in the Cascais region because of the favourable weather, wind and sea conditions. In 2007, Cascais was the official host of the ISAF World Sailing Championship for inflatable boats and racing yachts.

The winter months can be unpredictable with an equal number of bright, clear days and grey, humid days. In general, the weather is too cold to spend time on the beach, but in winter there can be great bargains.

It has the ruins of a castle, an art and sea museum, as well as parks and the charming cobbled streets of the historic center.
