I biked with Pablo and Karen through Colchagua and down to the pacific through beautiful countryside. We had alot of fun and exchanged lots of stories. Pablo is an attentive, empathetic and very knowledgeable guide. His maps of the regions we biked through are very incisive and add to the experience. I also hiked with Igor, an attentive and conscientious guide, high into the Andes on a well chosen route, we even saw a condor. Overall, I would very highly recommend Gradosur.
