Everyone goes to Santorini for the famous sunset in Oia. However, the moonlight at the black sand beach in Kamari is worth going as well. Plus, along the beach are shops, bars and restaurants one after another. Most of them are outdoor, so you can enjoy your favorite drink while enjoy the ocean under the moonlight.
Kamari is famous for its pebbly black sand, an aftermath of the volcanic eruption that occurred here thousands of years ago. It's also one of the hippest party spots on the island: the entire beachfront is lined with restaurants, shops, bars, and cafes.
When you're done lounging seaside, grab some grub and a few drinks, and meet the locals. The moonlit nights here are spectacular.
