This tour was such an amazing experience! Sergio was great, super easy to contact and very knowledgeable. He was very friendly and easy to talk to the whole time, showed us some of the most beautiful views!! My husband and I decided to do this as part of our honeymoon and it was perfect!
Sergio was fabulous! So enthusiastic and fun. We saw way more than we could ever have done on our own. We travelled roads I would not have even attempted. Sergio was always thinking ahead altering the route to accommodate ever changing weather conditions. This tour was a major highlight of our time in northern Portugal
Sergio was an amazing and well educated guide. He was attentive and engaging. We can also tell he loves what he's doing and will definitely recommend to our friends and family. Thank you Sergio!
