The Rescia caves, located in Claino con Osteno on the opposite side of the lake to Parco San Marco, are a natural jewel that are well worth a visit for their uniqueness.

Along the route, you can admire the 70-metre-high Santa Giulia waterfall from a natural opening in the gorge.

Park guests can book a day excursion to the caves, which includes a guided tour and transfer by private boat.
