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!
Sérgio was knowledgeable and kept us entertained the entire tour. We would highly recommend him and book him again. He was also able to advise us on restaurants near our hotel and offer insight for further trips in the future.
Sergio was very friendly and accommodating and picked us up at our hotel as well as dropping us off there making it very convenient and easy for us. He served us delicious food and wine and was very knowledgeable about all the details of the mountain. He was extremely informative.
This was a wonderful 4 hour long trip in a 4 wheel drive vehicle in the high Estrella Mountains. The scenery was amazing and we got to see places we would not have been able to access otherwise. Our guide Sergio, was very friendly, knowledgeable and informative and even brought delicious local wine and cheese for us. I would highly recommend this trip to everyone.
He knows all about the area and is willing to share all his knowledge. We had a fantastic trip and some very interesting discussions. We can highly recommend this tour for everyone with interest in local history/culture. And the nature is stunning.
Sergio is not only a phenomenal guide, passionate about history, geography, art, and literature — he's also a truly exceptional person who goes above and beyond expectations. His thorough explanations, his ability to connect personal stories to the tour experience, and his wonderful sense of humor and warmth make the entire trip deeply enjoyable.
Great thoughtful guide . A lovely experience
Very cool! We really enjoyed our evening with Sérgio!
