It's totally worth going for this event. The guide Ricardo is a very cool guy, and he arrived with his beautiful dog, which ended up the star of the show. It's a very pleasant hike where you get to see the beauty in nature just outside Porto. It is not a fast-paced trek, so it's definitely good for people of all ages, and the guide was always making sure we're ok with his pace. This opportunity cannot be missed because apart from the many scenic views, you also get the opportunity of a picnic at the end. It's a wonderful experience to sit down and relax, savouring local traditional food and absorbing the nature around. All in all, it was a fantastic experience and would not hesitate to re do it.
