Destination guide
Lisbon: Hills, tiles and the cheapest gateway to Europe
Lisbon is often the least expensive transatlantic gateway from the East Coast thanks to TAP Air Portugal, which also offers free stopovers on the way to the rest of Europe. Pastel de nata, trams, fado and day trips to Sintra and Cascais make it worth more than a stopover.
Best time to visit: March–May and September–October are sunny and comfortable. Summer is hot and busy; winter is mild, rainy and cheap.
