Don't just wander around the earth's surface — investigate what's underneath it too. See strange natural formations and shapes in the deep, shadowy recesses of Grotta SantAngelo.
You'll be spoiled for sightseeing choice when staying in Pietracamela. Grotta Sant'Angelo is a good place to begin here, but there are lots of other worthwhile sights to discover. Gran Sasso e Monti della Laga National Park, Gran Sasso d'Italia, and Sanctuary of San Gabriele dell'Addolorata are near the natural underground attraction and and will cap off your day nicely.
