If there's paradise lost, then this must be paradise found! I was walking up along Corso Garibaldi, which itself was obscure and lonely enough, when I caught sight of the sign which pointed to this park. So I heeded it, and after two tiny lanes and through an iron gate, I ended up in paradise!
The Parco di Ponte San Angelo is a very well-hidden gem in Perugia. Unlike the noisy and tourist filled park at Piazza Italia, here you can have the whole place to yourself. And the view is a fierce competitor to that at Piazza Italia. Here, instead of seeing Assisi, you get a great view of the Perugian plains, including a lovely faraway hill, one of the "legs" of the star shaped Perugia, with countless charming houses on it.
There are adequate benches and even a nearby WC. To get to the park, from Piazza Fortebraccio, head uphill along Corso Garibaldi (there's a TIM telephone and internet center), about 300meters uphill you will see the sign (see picture included) that directs you to the park. Then you're just one minute away!
