The Black Sea is just delightful on a clear night. Especially during a cruise beneath the moonlight for three hours on a ship. There's an open bar, acoustic musical performances on the lower deck and two upper decks for serene stargazing in a very tranquil setting.
Climb aboard in Nessebar and settle in with a drink from the open bar as the boat pushes out into the moonlit waters of the Black Sea. After setting sail, you can choose to remain in the enclosed lower deck to take in the sweet sounds of an acoustic guitar player or to ascend to the upper decks.
Spend a tranquil three hours gently gliding through the water, watching the lights of the coastline drift by, or laying back and letting the stars and the moonlight wash over you.
