The Baggero oasis is two beautiful lakes created from old excavations of the Merone cement plant. You can walk the entire ring that surrounds the two lakes, there is a playground and a hostel. The best times to go are spring and autumn, when it's not too hot. Ultimately it is a place worth visiting, especially on foot.

The Baggero Oasis is the result of the environmental recovery of a large area previously used for mining, located between the municipalities of Merone, Monguzzo, Lambrugo and Lurago d'Erba. Started in 1970, the redevelopment process led to the creation of two lakes in old marl extraction excavations. The area offers pedestrian paths, cycle paths, a children's play area and an innovative Stellar Oasis for astronomical observation. The old cement plant warehouse was converted into a "Park Center" inaugurated in 2015, equipped with classrooms, conference room and a hostel with bar/refreshment area. The Baggero Oasis is also a starting point for exploring the Lambro Valley Park, offering initiatives to experience and discover the natural beauty of the area. It is located in Merone, with access from via Cesare Battisti.

To see the illuminated Cross I left at 4.20pm from the Alpe del Vicerè car park. At 5.15pm I reached the top of Mount Bollettone keeping a good pace and a few minutes later it lit up! To go down you need a front panel even if the road is easily passable
