If you're looking for outdoor fun, pay a visit to Monte Amiata. No easy stroll around the block, this hike is fantastic for some mid-vacation exercise.
When you've spent some time at this steep landmass in Abbadia San Salvatore, why not check out Baths of San Filippo, Mount Amiata Fauna Park, and Mercury Mining Museum of Monte Amiata? They're not far from Monte Amiata and also a favorite with many travelers.
