The city center has a low part called the Baixa and high parts called Bairro Alto and Alfama districts, which can easily be negotiated on foot or by taking one the many elevators available. Lisbon is quite pedestrian-friendly, with plenty of squares, parks, and crossings, so getting around is a breeze.
How hard is it to walk around Lisbon?
Lisbon is a very walkable city, as long as you're willing to contend with some steep hills. The city is very easy to explore on foot if you're in good health, but the narrow, cobbled streets and many steep inclines can make it challenging if you have limited mobility or reduced fitness.
What is the best time to go to Lisbon?
The best time to visit Lisbon is either from March to May or September to October, because the weather is still warm, hotel rates are cheaper and there are fewer crowds than in summer. In those seasons, you might also be able to squeeze in a few beach days.
