We recently returned from a trip to Spain and I am happy to enthusiastically recommend PureMountains.com for those who want to experience mountain biking in the Sierra Nevada National Park of Spain! Jenny and Tim are the owners of this off-the-grid farmhouse where they take very good care of you and feed you well. The rides are challenging and oh-so-fun, and there's always an option to ride a leg in the landrover that would meet up with us along the way at different points. If anyone wants more information, just let me know!
