Near Massa Marittima, we find Lago dell'Accesa, of great naturalistic, environmental, and historical-archaeological interest, so much so that its evocative atmosphere has given rise to numerous legends. Of karst origin, the lake is approximately 38 meters deep and feeds the Bruna River, its only estuary. Besides being suitable for swimming, it offers refreshing summer refreshment thanks to the typical vegetation surrounding it, consisting of reeds, rushes, poplars, and eucalyptus trees, as well as typical Mediterranean scrub. It is ideal for pleasant walks along the shore, and nearby mountain bike enthusiasts can explore a variety of trails, most of which are easy and fun. The crystal-clear waters are populated by a diverse fish fauna, including trout, pike, carp, and perch, as well as an equally rich population of aquatic birds.

The Accesa area is also extremely significant from an archaeological perspective. Near the lake, in the Macchia del Monte area, numerous excavations were carried out as early as the 1930s, and resumed in the 1980s, bringing to light numerous remains of four Etruscan villages dating from the 9th to the 6th century BC. The buildings of the various settlements, of which only the foundations are visible, are gathered in scattered groups within a rather large area. Given their location, it is hypothesized that these villages were linked to mining, especially copper from the Fenice Capanne and Serrabottini mines. It is also thought that these mining villages were mining outposts that were subordinate to the large center of Vetulonia, to which they supplied raw materials. In addition to the complexes intended for housing and mining, many tombs of various types (pit, pit, circle, and chamber) were also discovered.

The Fontino trail is challenging and technical in many sections but really beautiful... the final part is much smoother and easier to drive... at the end of the trail you find yourself on the banks of a small lake.
