San Michele in Bosco is on Bologna hills but very easy to reach, both by bus (30) or walking.
If you decide to walk I suggest to go up from Porta S. Mamolo (Via Codivilla) entering the park you find down and reaching the church from the back.
Once up take your time to admire the view of all the...
The church is on a hill outside Bologna. There is a free parking close to it and we also saw a bus stop there as well. From there on it's maybe 2-3 minute walk to the church. The church itself is large, but nothing special, however you could get a great view of the city of Bologna from there.
Take an easy walk in fresh air through a lush garden park to the top of a hill where Church of Saint Michael in Bosco is located. The church has beautiful interior and interesting 2-levels inside design. The view of the city with its red-roofed houses is alsolutely spectacular. Definately reserve time for such 2-hours walking tour.
