Lake Bolsena is a large volcanic lake in central Italy, about 90 km north of Rome in the province of Viterbo, Lazio. It is a popular tourist destination, known for its natural beauty, clear waters, and relaxed atmosphere. The lake was formed by the collapse of a caldera of the Vulsini volcano. This geological history contributes to its black volcanic beaches, some of which are black in color. Lake Bolsena is known for its clean, spring-fed waters, which are excellent for swimming. The shores often slope gently, making it suitable for families with children. The lake has two islands, Bisentina and Martana, formed by underwater eruptions. Public access to the islands may be limited, but boat tours often offer views of them.

Lago di Bolsena is the largest volcanic lake (crater lake) in Europe. The lake lies in the previously volcanically active zone of the so-called Apparato Vulsinio. It fills a caldera that was formed by the collapse of underground magma chambers following powerful, explosive volcanic eruptions, an estimated 300,000 years ago

One of numerous necropolises in the area. While most of the others are fenced and (currently?) inaccessible, you can easily hike this one. There are some small graves to see.
