If you are not keen to go far by train, go for Porto’s ocean walk and their old tram.
The beaches of Porto will sweep you off your feet, I promise. I spent three days visiting different beaches and none of them failed to amaze me; one even had a church on it! Have you ever seen a church on a beach? You can also go on a day trip to Aveiro to visit the most colorful town you can imagine! Don’t forget to go for a swim too; it is not every day that you get to swim in the Atlantic ocean. If you are not keen to go far by train, go for Porto’s ocean walk and their old tram. You might even spot one or two lighthouses!
