What people are saying about Azores

A really, really great trip. Stunning views from the crater rim and lots of great stops in between at the Lagoon. The route is partly paved, most of the routes are off-road uphill and downhill! Perfect for the quads The views are simply fantastic and the trip is totally worth it! With Luis we had a very charming and humorous guide!

Very nice excursion well done with a plus the visit of a lava tunnel lost in nature and surely little known. Friendly and competent guide
