Lisbon attractions: what to see and do in summer Lisbon swelters under a cerulean blue dome for the summer months. "A praia" (to the beach) sings out from the city's sun-kissed, begonia blossomed streets as surf boards are stacked on top of cars and everyone makes for the beachy "burbs of Cascais and Estoril - 20 minutes drive from the city-centre. The aim being to cool off in the frosty Atlantic, get some sand between their toes, and tuck into the seaside classic of a plate of garlicky ameijoas (clams) washed down with a tumbler of brain-freeze cold lager. My hotel pick: LX Boutique, a modern, bright and airy hotel by the river June 13th and the days surrounding see Lisbon's biggest street party, St Anthony's Day - the patron saint of Lisbon. A carnival of floats take over the city-centre, and locals sell beer and barbecued sardines from every porch in the historic Alfama neighbourhood. From May 15th to June 3rd Lisbon goes music mad with the Rock in Rio festival, this year acts like Stevie Wonder and Bryan Adams are headlining.
