Once at the meeting point, your guide will briefly introduce the itinerary and the group. Electric bikes will be explained and tested too. Then, from the naval station close to the Commerce Square, board one of the traditional ferries from Lisbon to Cacilheiro and cross the Tagus River to Barreiro. In Barreiro, a train will take you and your bicycle comfortably to Palmela in approximately 40 minutes. In Palmela, the first trip is to cycle to the Castle. The Castle of Palmela is rich in history. In this zone, archaeological findings confirm human occupation from the neolithic period as early as 310 A.C. The earliest fortifications were built by the Muslims around the 9th century. From the hill, you can see the Rivers Sado and Tagus. If the day is clear, Lisbon and the Mountain range of Sintra are visible as well. In Palmela, visit archeological sites and have a coffee break. When leaving the Castle of Palmela, contemplate the beautiful Valley of the Barris, flanked by the mountainous forests of São Luís, Laurel and Arrábida.  Carry on along the less-frequented road of the Barris Valley, first on asphalt, then off-the-beaten-path between vineyards and sheep pastures. Arriving in the town of Nogueira de Azeitão, rest and  taste the region's famous Muscatel wine, tarts and buttery cheese. Burn some calories by cycling up the Arrábida Nature Park. As you go up, sights over the blue sea are of an indescribable beauty. Have a glimpse of the Arrábida Convent built in the 16th century. Finally, in the town of Setubal, take a well-deserved break and share your impressions around a table while savoring some fresh fish. Return to Lisbon by train.
