Hi If the bike is not suitable for these trails then a horse is fine too. I offer bike rides as well but at the moment I would like to promote my site ,http://patagoniatrails.cl/horse-trips/andean-patagonian-expedition-puelo-river/ Enjoy a riding holiday in Patagonia, South America. Starting at 3000 u$ 8 days . Unforgettable river crossing and amazing blue lakes.
