Walking from Riomaggiore to Manarola might have been my favorite part of the day. It took about 20 minutes to walk between the towns and, the walk was easy. Paved the whole way. When a walk is quick and easy it's an added bonus when it's gorgeous!
The path is called 'Via dell'Amore' (walk of love) and is partially cut out of the steep cliffs next to the sea. There were tons of benches over looking the sea and at one point we even came across a small cabana style bar that hung out over the water. People had been signing their names on the rock cliffs for years and it was insanely fun to read all the names and dates (and of course add our own!). There was a section of the path where couples have been placing locks and throwing out the keys. (I think this might have been in a movie at some point and now people do it everywhere? Not sure. Anyways, it was cute.)
In summary, the walk was fun and pretty and it was one of the best parts of the day!
