Another very popular day trip from Lisbon is a short train ride to the very popular beaches of Estoril and Cascais. Albeit not really dreamy, especially on hot summer days, a day in these sophisticated retreats on the shores of the Atlantic Ocean can be the perfect break from Lisbon’s big city life.

If you spend more time in Estoril, you should stay away from the beach and go on a day trip to Sintra. Even by public transportation, this town of palaces is less than an hour away.
