Traveling within Lisbon is easy with the metro, bus, and tram system. Get a rechargeable Lisboa Card for unlimited transportation and attraction access. Trains are also available for day trips to Sintra and Évora.
If wanting to extend the trip, consider spending an extra day in Sintra, explore the beaches in the nearby Algarve region, or take a trip to Porto for a different experience. If shortening the trip, consider cutting the day trip to Évora and spending more time in downtown Lisbon.
