Just a short distance from the Amalfi Coast, the Emerald Grotto (Grotta dello Smeraldo) near Conca dei Marini reveals a rare natural show: sunlight filters through an underwater opening and turns the seawater a vivid green, casting emerald tones across the cave walls. Discovered in 1932, this quieter alternative to Capri’s famous Blue Grotto gives visitors an intimate experience of dramatic color and impressive rock formations without the crowds.
You don’t need to ferry to Capri to see it. The grotto is reachable by boat or by a brief bus ride from Amalfi; if you take the bus, descend the steps or use the elevator to reach the entrance. The boat approach along the rugged coastline is especially scenic and often feels like part of the attraction itself.
Visits are made in small wooden rowboats. As sunlight enters through the submerged opening, the water takes on shifting shades that range from deep jade to bright turquoise, usually at their most striking around midday. Guides sometimes splash the oars to enhance the glow, but try to find a calm moment to look down—the clear water often reveals the seabed nearly 40 feet below. Also look up: stalactites hang from the ceiling and stalagmites rise from the floor, with some columns joining to form dramatic natural pillars.

Beyond its visual appeal, the grotto has collected local stories and traditions. Folklore speaks of spirits and whispered echoes inside the cavern, and a more tangible tradition is an underwater nativity scene installed in 1956. Divers visit annually in December to place flowers at the seabed shrine, a ritual that ties the site to local faith and custom.
The cave is best enjoyed in quieter moments. Weekends and the month of August bring many visitors and higher noise levels, which can diminish the sense of wonder. If you must visit during busy times, aim for a morning slot. Booking in advance is not necessary, though cash can be helpful for securing boat rides at any time.
Pair the grotto visit with a stop in Amalfi for breakfast. Sample a sfogliatella— the region’s shell-shaped pastry filled with ricotta and candied citrus—alongside a strong Italian espresso at a long-standing pasticceria. While in the grotto, keep phones stowed if you can: the colors are difficult to capture accurately on camera, and the small rowboats make it easy to drop a device overboard.
After visiting the cave, spend time in Conca dei Marini, a charming village that feels removed from busier tourist hubs. For lunch, choose a seaside restaurant and try scialatielli ai frutti di mare, a local pasta tossed with mussels, clams and shrimp, best enjoyed with a glass of regional wine and a view of the sea.
