This place was undoubtedly the "highlight" of this stage! Already arriving in the valley, you get the impression of entering another world, literally: the Grigne mountains loom, almost vertical, closing off the valley, the steep road descending towards the stream becomes a small path, the vegetation becomes dense... almost a jungle. finally, you arrive at this spectacular cave, a natural bridge, a very cool place where it is mandatory to stop... also because, immediately after, you climb a very steep staircase!

Alpe Moncodeno is a mountain pasture that is still in operation today. It is one of the most loved places on this side of the Grigne, above all for the large quantity of mysterious caves. There are more than 600 of them, but the most famous is perhaps the "Moncodeno cave": an eternal ice sanctuary visited and mentioned by Leonardo da Vinci, which offers a cool refuge even on the hottest summer days.

The "Crot di darden" is a cave so called because of the sparrowhawks that nest there. It is located at the end of the Valle dei Mulini, after a stretch of path along the riverbed. Beautiful to look up and see the rock above you.

The region around Taceno, particularly the Grigna mountains and Valvarrone area, offers several significant caves. Among them are the Meria Stream Cave, known for its tranquil river flowing into a cave, and Ferrera Cave, a large collapse chamber with historical mining significance. Another unique spot is Crot di Darden Cave, named for the sparrowhawks that nest there.
Yes, the Ferrera Cave (also known as Acqua Bianca Cave) near Mandello del Lario is notable for its past iron hydroxide extraction activities, with traces of these excavations still visible. Leonardo Da Vinci is even said to have mentioned its charm. Additionally, the Feldspar Caves in Valvarrone offer a glimpse into the valley's industrial heritage, where feldspar was mined for ceramics and glass production.
Yes, the Moncodeno Cave (Grotta di Moncodeno) near Esino Lario in the Grigna mountains is famous for its 'glacier part,' a unique section containing ice. Historically, it served as a natural ice factory. An internal path with an iron staircase makes this icy section more accessible, and guided visits can be organized through mountain guides.
While many caves in the Grigna mountains are for expert speleologists, some, like the Meria Stream Cave, offer small areas for stopping and resting, making them more approachable. For specific family-friendly options or beginner caving, it's advisable to check with local guides or visitor centers for current accessibility and safety information.
The Crot di Darden Cave in Valvarrone is specifically named because sparrowhawks (locally known as 'darden') nest there, offering a unique opportunity to observe these birds. The diverse ecosystems around the caves also support various other local wildlife.
The best time to visit depends on the specific cave and your activity. Caves like the Moncodeno Cave, with its glacier part, can offer a cool refuge even on hot summer days. For general exploration, spring and autumn often provide pleasant weather for accessing cave entrances and surrounding trails. Winter visits might be possible for some, but require checking specific access conditions due to snow or ice.
For caves like the Moncodeno Cave, guided visits can be organized through mountain guides to ensure safety and provide expert insights into their unique features. It is recommended to inquire locally for guided tour options for other caves as well.
The region offers a variety of outdoor activities. You can explore numerous hiking trails around Taceno, ranging from moderate to difficult, such as the Historic Mule Track from Vendrogno to Margno. There are also running trails and cycling routes, including scenic loops like the Sprizzotolo Waterfall – Pioverna Stream loop.
When visiting caves, it's advisable to wear sturdy, closed-toe shoes with good grip, as surfaces can be uneven and slippery. Layers of clothing are recommended, as cave temperatures can be consistently cool even on warm days. A headlamp or flashlight is also essential for visibility inside darker sections.
Yes, besides the Ferrera Cave's past iron hydroxide extraction, the Valvarrone area features Feldspar Caves, such as the 'Cava di Lentree,' which are remnants of historical mining activities for feldspar. The Casiss Mines also represent a historical site where manganese was extracted.
The Grigna mountains are a significant karst area with approximately 1100 mapped cavities. The Museo delle Grigne in Esino Lario offers a natural history pathway that includes information on the local caves and the region's rich geological interest, which has fascinated scientists for over a century. Esino Lario itself is known for its numerous fossils and karst phenomena.
Access to some caves, like the Ferrera Cave, is typically from nearby villages such as Rongio, where parking might be available before continuing on foot. For other caves, specific parking information varies, so it's best to research the particular cave you plan to visit or inquire with local tourism offices.
