Porto is an amazing place to visit and with many of the budget airlines such as Easyjet and Ryanair serving this place, its also a really cheap getaway for a weekend. Here are the top 3 things to do on a budget in Porto: 1. Ribeira and the Luis I Bridge is one of the key features of Porto. The riverfront district was declared a UNESCO World Hertiage Site and should be top of your list. It has an amazing atmosphere and lots of old and charming buildings to see. Views from the top of the bridge are amazing and you can walk across the top and the bottom. 2. Livraria Lello os a bookstore and is worth a walk from Ribeira, there is a small charge to go in but this is taken off a purchase. It can get busy and queues can get long quite quickly. 3. Sao Bento Railways Station in Porto is located in the historic centre of Porto. It features large panels of azulejo tiles and looks absolutely amazing. Its always difficult to photograph as the place can get busy at most times of the day, even for the early risers.
