Forte Diamante, Sant'Olcese

The direct hike that leads up the hillside is definitely invigorating and requires supportive athletic footwear, but it is much closer to 30 min rather than the posted 40 min. Park near the charming and well-menued trattoria, use the restroom and maybe grab a snack and a beverage beforehand if you didn't bring any (or definitely dinner after). A truly beautiful way to spend a few hours on a clear and warm day.

Really good place for a trip outside the city centre. Amazing views along the way, the fortress itself is also nice to explore. It seems it's oficially unaccesible, but at the time of my visit the doors were open and some warning signs were lying on the ground. Unfortunately, only the ground level was easily accesible.
