Grotta Azzurra, Sea cave in Anacapri, Italy.
Grotta Azzurra is a sea cave on the coast near Anacapri that extends about 50 meters into the cliff face. The entrance is quite narrow, so visitors must lie flat in small boats to pass through.
During Roman times, the cave served as a private bathing spot for Emperor Tiberius and held statues of Neptune and Triton. In the 1800s, German writer August Kopisch and painter Ernst Fries drew international attention to this location.
The name comes from the striking blue color of the water, created by how light filters through the cave. Local people and visitors have long regarded this spot as both a bathing destination and a natural wonder that sparks imagination.
Access to the cave depends heavily on weather conditions, with frequent closures during winter months. Plan your visit for calm weather and bring sun protection, as the boat ride and the water can be quite bright and sunny.
Light enters through an underwater opening and reflects upward through the seawater, creating the distinctive deep blue color. This effect changes depending on the time of day and sun angle, making each visit feel slightly different.
