For the best beach on the Estoril coast, and amazingly so close to both Lisbon city centre and just 4km east of Estoril, head for Carcavelos. Carcavelos has a bohemian surfing mecca edge too - surfers flock here in their droves for the best beach waves, and superb nightlife and choice of accommodation.
Much of the action at Carcavelos goes on down on the beach. It gets crowded here at this top Lisbon Holiday coast beach in peak season, and the huge number of surfers in the water can be a little dangerous so watch out for that. Water quality has improved here considerably in recent years. In truth surfers in the know tend to head for Ericiera to the west where water quality and waves are better.
Carcavelos is still a little sheltered, so tends to pull in beginner surfers and families. It's an ideal base for easy access to Estoril just to the west (4km), and Lisbon city centre to the east (12km) on the Cascais mainline rail route.
Crammed with restaurants, bars, a little nightlife and topped off by an endless sandy surfing beach, Carcavelos has much to offer as a holiday base.
It's bustling and lively here (if you want more peace head further west, or settle for smaller Paco de Arcos).
