Have fun in Lisbon without spending a cent

Wild Walkers is a low-cost tourism company – so low cost that some of their activities are actually free, including their tours. Even if you are not a backpacker, pick up a rucksack and join them to see an alternative side of the city, with food and street art in the mix. Each tour takes approximately two and a half hours and goes through the Alfama, Graça and Bairro Alto districts, depending on the day and the group’s mood. At the end, if you enjoyed the tour, you’re supposed to tip your guide.

If you want to ride a bike for free, you will have to go to Cascais. There you ride as much as you want for free as long as you return the bike at the end of the day (the winter schedule goes from 9am to 5pm). Bicas, Cascais’s citybikes, can be picked up at several locations (next to the train station, near the Casa das Histórias Paula Rego or at the Guia). You just have to present some form of ID.

Panorâmico has the best 360-degree view of Lisbon and is located on the top of the Monsanto park, right next to the Air Force base. There is usually a police car patrolling outside, so make sure you avoid bumping into someone or this free ride might turn out to be expensive. The side netting of the old restaurant (opened in 1968, later turned into a bingo parlour) is easy to clear, and then you will have the city at your feet. It is located in the Estrada da Bela Vista and you can easily find it on Google Maps.
