Cascais is a small beach town in Portugal next to Estoril coast in the greater Lisbon area. Cascais, former residence of the royal family and pioneer of tourism in Portugal, is a very charming village. Dominated by the bay and the imposing Cidadela fort, the historic centre is brimming with architectural treasures of a religious, military and civil nature. Likewise, the museums of the Sea, Casa das Histórias de Paula Rego, and the Municipal Museum Condes de Castro Guimarães are also must-see attractions. Cascais is surrounded by popular beaches, such as Guincho Beach to the west, and the lush Sintra mountains to the north. Some of its shoreline is cliff-y, attracting tourists for its seascapes and other natural sights such as the Boca do Inferno. It is also becoming a popular golf destination, with over 10 golf courses nearby. Surfing, sailing, windsurfing, and kitesurfing are also popular in the region around Cascais due to favourable weather, wind, and sea conditions. In 2007, Cascais was the official host of the ISAF World Championship in sailing for dinghies and racing yachts.
