For a relaxing day trip, take the train to the former fishing village of Cascais. Here you can stroll on the beautiful decorated streets, experience the lively fish auction held every afternoon next to the main beach, visit "Museu do Mar" to see the rich history of Cascais or take a refreshing walk along the coastal road to Boca do Inferno ("Mouth of Hell") where high waves crash into gigantic caves.

The Museum of Science & Industry has something for visitors of all ages. The museum offers an array of hands-on activities, including lying on a bed of nails, exploring optical illusions, solving brain puzzles, and diving into a NASA-funded lunar colony simulation. You can also observe butterflies, enjoy a round of mini-golf, and gaze at the stars in the planetarium. Come with time to spare because you will probably want to spend the entire afternoon here.

A UNESCO World Heritage site, the Old Town charms with its colourful townhouses and the exceptional atmosphere of its narrow streets. When in the Old Town Market Square, you'll meet a mermaid — the official symbol of the city. Don’t forget to see the Barbican, stop by the bell on Kanonia Street, and walk along the old city walls. You should also visit the Royal Castle. Apart from the royal apartments, the old seat of Polish rulers also houses an art collection with paintings by Rembrandt and Bernardo Bellotto, also known as Canaletto. One awesome way to quickly see all of Warsaw is with a tour in a tiny yellow retro Fiat 125p. Of course, you can ask the guide to tailor the drive to your interests.
