We really enjoy our tour in Sierra Gorda. Carlos is an excellent guide and we had an awesome time in Sierra del Bernal.

Even when unfortunately there was only 1 day available sparetime on a short trip to Queretaro, it was really worth to spend it organized by and together with such a local specialist and experienced guide like Carlos.

Last july we booked a canyoning expedition with Exxi challenge. The weather had been optimal, but the week before some downpurs threatened to have our plan cancelled.

Would definitely recommend Exxi challenge

EXXI provided excellent speaking guides and loads of fun in abseiling two casacada's very near Queretaro. Carlos and Brenda made the trip interesting and fun. Carlos has much knowledge of the area and sharea history and special tidbits. Exxi is flexible and was able to meet our timeline. Thanks EXXI!
