3 must-see hop-off attractionsWe don’t think your visit to Porto will be complete without hopping off the bus to see these three destinations. The first is the city’s stunning cathedral, Sé do Porto, which stands high above the River Douro. Built near the old city walls, some say the cathedral looks as much like a fort as a religious building. One thing everyone agrees in is that the views from its location are spectacular. The next place that you have to hop off at is the Torre dos Clérigos. This impressive tower is 75 metres tall and the views from the top over the city and the river are more than worth the climb up the 240 steps. Our final recommendation is also all about the view. Hop off at the Teleférico de Gaia to ride the modern cable car that takes you over the rooftops of Gaia and offers you some of the very best views of the city.
