About Grøtsund and Ullsfjord Lighthouses Lighthouse
This fiberglass tower, built in 2018, stands on a point of land at the south side of the Grøtsund, a passage leading northeast from Tromsø. Standing 6 meters tall, it replaced an earlier square wooden tower. The structure is white with a red roof and features three black horizontal bands. Its light emits two white, red, or green flashes every 8 seconds, with the color changing depending on the direction of approach. The geographic range of the light is 8.4 nautical miles. The nearest port is Tromso, 9.2 km away.
Why it matters: The directional light system is essential for guiding vessels through the narrow Grøtsund passage, preventing groundings and ensuring efficient maritime traffic flow.
