Punta Corvo beach is below the town of Monte Marcello - and is the only sandy beach in the village. Other beaches around Monte Marcello (which is both the name of the village and mountain peak) you'll find at Lerici and Bocca di Magra, on either side of the peak. Punta Corvo is voted as one of Italy's 30 most beautiful beaches.
There are two ways to arrive here, either from the water by boat (private boat as there is no public boat services to this beach), or via a path from the village of Monte Marcello. You can park at the beginning of the path in the village where there are also two coffee shops. The path starts out paved, then becomes uneven and it's approx. 700 steps down to the beach! It's quite a trip back and should only be considered by the fit and able.
The difficulty level is medium, but most of the trip down is through the forest, so there is shade along the way. Moreover, there is also a bench or two on the way where you can take a much needed rest. It usually takes about 30 minutes to get down and of course a bit more to go back up. There are signposts to help you find the way.
The walk is worth it and at the end you will find a beautiful sandy lagoon with almost black sand. The lagoon is a few 100 metres long - and there is the option to either bask on the sand or on the rocks. The view towards the sea and Portovenere above on the other side to the right when you turn outwards. The sides of the lagoon are well protected by rocky slopes. Take some form of shade and water as there are no beach services available here.
