This is a road for curve lovers. The SS67 links Florence and Forli and gives a wide range of emotions with a single theme: drive carefully and eat well! The Muraglione Pass is also known as the Artusi Pass in memory of Pellegrino Artusi, the writer of "Science in the Kitchen and the Art of Eating Well" from 1891.
From Florence the road runs smoothly to Dicomano, a town which has a soft spot for vintage motorcycles (with vendors and biker fests). Two more kilometers and then at Carbonile there's an S turn across a bridge (watch out for ice in the winter). 5 more kilometers brings you to San Bavello and a very sharp curve to the right. You're still in time to warm up your tires: do it before San Godenzo.
In Piazza at San Godenzo, it's worth visiting the Abbey of San Gaudenzio. Situated on the Linea Gotica, this courageous town won a silver medal for its hard work in the Partisan struggle against the Germans in WWII. If you skipped this town, visit Castagno d'Andrea - it's perfect for a picnic. If you turn off towards Castagneto you can visit the restaurant and town by foot after a long meal.
From here on out it's between you and the road. Be careful. There are curvy mountain roads that are tight and narrow. The climb is steep and the view of the Casentino Forest is beautiful. Once you pass Cavallino you are already on the short stretch towards the mountain pass, just in time to watch the GP motorcycle races with Giovanni at the Bar del Muraglione. Here, near the wall built in 1836 for the Granduca of Tuscany Leopoldo II, every weekend there's a biker fest.
The Romagna side of the mountain is tough also, and the roads require concentration. A special thanks goes out to the Montone River and to its valley which is so inspiring. Reaching San Benedetto in Alpe, hiking lovers can put down their kickstand and explore the waterfalls of Acquacheta (a quick excursion of three hours), which is even mentioned by Dante.
SS67 has lots of distractions, such as the deviation off to the right towards the Manzo Pass, past Bocconi, or stop and see the smallest volcano in Italy to the left, on SP22 of the Monte Busca pass. The final handful of kilometers brings us to the Portico di Romagna, which has lots of nice hotels and fine Artusi-inspired restaurants.
