Mountain biking around the canyon with Oscar Javier was our favorite thing we did during our time in Colombia! He was very knowledgable about the area, and eager to show us as many beautiful view points as possible. Near the end of the tour, he even took us to a market where we had some of the best local food that we've ever had in our many travels. Would definitely recommend this tour, and if we ever find ourselves back in the area, then we would love to do one of his other tours!
