Best caves around Ronago are primarily located within the Lanza Valley Park, an area characterized by its two main waterways, the Bozzente torrent and the Olona river. This geological setting has led to the formation of significant sand and gravel deposits. These deposits were historically exploited through quarrying, resulting in various cave formations. The region offers a combination of natural and man-made subterranean sites, many of which are now recognized as natural and cultural heritage.

The Malnate caves are located in the heart of the Lanza valley park. They are very ancient sandstone quarries: in fact they date back to 25 million years ago, when they originated on the seabed. In the past they were used for the extraction of sandstone blocks, today they are recognized as natural and cultural heritage.

The From Mines to Fossils site is a famous fossil mine, a World Heritage Site, offering insights into a world 240 million years ago.
Many caves, particularly the sandstone quarries like the Sandstone Caves of the Molera Gorges, feature large vaulted rooms connected by passages, with reflections on pools creating unique geometric perspectives.
