Lisbon is a great place to spend New Year's Eve for many reasons! Although it's chilly spending New Year's Eve outside in Europe, Lisbon in the offseason is one of the warmest places on the continent, and its a wonderful time to visit the city as there are usually less other tourists and it's more cost effective too.There are free public events in Praça do Comércio, the main square, as well as along the Tagus River. You'll be entertained by musicians and bands (although they may only speak and sing in Portuguese!) before the large fireworks displays take place at midnight.Don't worry though, the party continues afterwards if you want to stay out! There are lots of smaller neighbourhood events where the locals decorate small squares in their area and then bring out tables to all celebrate together, which is lovely to see. And you can wander the streets of Alfama or Bairro Alto and find plenty of parties taking place in bars and restaurants too, with people staying out dancing until the early hours of the morning, or even later!
