Traccion a Sangre Mountain Bike y Trekking is an outdoor adventure company in Puerto Piramides. They came highly recommended to me by a friend but unfortunately we couldn't go on a tour with them because of traveling with our two small toddlers and being sleep deprived at the time (personal decision). It is the thing I want to do most of all on our inevitable next trip here.
š“š»Traccion a Sangre offers guided mountain bike and trekking tours that allow you to see areas of the peninsula that you would never see otherwise. There are different tours to choose from ranging from 3 hours to longer 6 hour excursions.
Personally, I would recommend a bike excursion to really go further afield and see as much as possible. But if you would prefer not to bike, the hiking tours are a great option. Confirm skill levels for each excursion as they range from easy to more difficult.
ā Don't forget to pack plenty of sun protection. You will be exposed to the sun on any hike or bike tour here, there is no forest here to offer shade. The sun in Patagonia is very strong. Bring a sun hat, plenty of sunscreen (which is expensive in Argentina), and long sleeve clothing like these sun shirts.
