Mount Solaro
is a massive, limestone formation that emerged over time in connection with the
other great masses of the Sorrentine peninsula. It was then radically disturbed
by drastic shiftings that left the layers skewed at some angles. The eastern and southeasters slopes of the mountain are severely eroded and fall straight down to the sea, while a broad slope descends towards Anacapri, full of spontaneous and imported vegetation with more than 850 species.
