About Scoglio Grosso
Scoglio Grosso is a boat dive between Ponza and Zannone built around a rocky canyon, steep walls, and a natural arch. The upper section starts around the mid-teens, while the main wall drops into the high 30s and low 40s. Current is part of the site, and the moving water often brings barracuda, jackfish, tuna, groupers, moray eels, and other life through the rocky breaks.
