Things to do in Lisbon

March to June and September to October are warm and sunny without the peak crowds. July and August are hot and busy, and winter is mild, with some rainy days.

Yes for most travelers. Guided trips handle the transport and the timed entry to palaces such as Pena, and many combine Sintra with Cabo da Roca and Cascais in one day.

Three days covers the main neighborhoods, Belém and a food tour. Add a day for Sintra and the coast.

For popular tickets and small-group tours, a few days to two weeks ahead is a safe window, and more in peak season or around holidays. Many day tours and food walks still have space a day or two before, so it is worth checking live availability even for last-minute plans.

Many experiences include free cancellation, usually up to 24 hours before the start time. Each listing shows its own policy, and the ones marked "Free cancellation" can be cancelled for a full refund within that window.
