If your travels will take you to the Lucca and Versilia area, turn your sights toward the Grotta all’Onda in Casoli, part of Camaiore. It’s quite a sight to behold even before you go in: miniature waterfalls trickle down its exterior walls, creating a postcard-perfect effect.
Beyond aesthetic appeal, the cave has scientific and social significance. For the former, it still contains traces of the major sedimentological and paleoclimatic events starting from about 170,000 years ago; in terms of the latter, it housed Neanderthals who left behind both their flint hunting tools and the bony remains of their prey. Grotta all’Onda is accessible year-round from a low-intensity C.A.I. hiking trail.
