The harbor is one of the most popular guest marinas in Finland, often recognized as the 'Sun City' of the country due to its high number of sunshine hours.
The town of Naantali was founded around the medieval Birgittine convent, the stone church of which still dominates the skyline near the harbor.
The harbor serves as a focal point for the annual Sleepyhead Day festival, a tradition where the town's most lethargic person is thrown into the harbor waters.
The marina is located at the intersection of several major nautical routes in the Archipelago Sea, the largest archipelago in the world by number of islands.
Naantali Guest Harbour is a major nautical hub in Southwest Finland, located in the heart of the historic wooden old town. It serves as a primary port for leisure boaters sailing the Archipelago Sea, offering over 300 berths. The harbor is situated directly adjacent to the summer residence of the President of Finland, Kultaranta, which is visible across the water. The surrounding area features traditional pastel-colored wooden houses, restaurants, and seaside cafes. As of August 2026, the marina provides comprehensive services including electricity, waste management, and fuel stations. It acts as the gateway to the Moomin World theme park located on Kailo Island. The marina is deeply integrated into the town’s layout, making it a central point for maritime culture and seasonal tourism.

Arrive early in the day during mid-summer to secure a mooring spot, as the harbor reaches peak capacity quickly.
Check the wind direction before docking, as the harbor can be exposed to crosswinds depending on the berth location.
Utilize the harbor's proximity to the old town to walk to local bakeries for fresh Finnish pastries.
Do not attempt to moor in spaces marked with private or permanent residence signs; avoid blocking fuel station access during peak weekend hours.
The marina operates primarily as a seasonal facility, fully active from late spring through early autumn, with limited services in winter.
Maintain quiet hours during late evenings to respect boaters sleeping in the harbor; follow local maritime waste disposal protocols strictly.
