Santa Marta Beach is great for swimming
The first beach in the protected Sintra-Cascais Natural Park is formed by an inlet and is quite small, but its location between the Cascais marina and the Condes de Castro Guimarães Museum attracts tourists on the sunniest days. Due to the proximity of the boats, the water may not always be the best for swimming, but it’s crystal clear. There isn’t much sand on high tide (it’s mostly found by the palace of the Condes de Castro Guimarães Museum), but it’s quite a beautiful place, making it something of a fairytale beach and the most Instagrammable in Cascais.

Local kids often get together to jump into the water from the rocks, as tourists watch or go for a swim.
A bike path starts here and follows the coast to Guincho, about 8.5km (5 miles) north, passing by Boca do Inferno on the way.
