Five Finger Islands Light

Five Finger Islands Light is a white concrete lighthouse tower near Petersburg that rises 68 feet above the water to guide ships through the channels between Stephens Passage and Frederick Sound. The structure features a functional modern design with its lantern room positioned higher to ensure visibility across the surrounding waters.

The United States Lighthouse Service built this navigational structure in 1902 to guide ships through the local waters. After a fire destroyed the original building in 1933, it was replaced with the concrete tower that stands today.

The lighthouse stands as a testament to early 20th century maritime navigation, representing one of the first government lighthouses constructed in Alaska.

The beacon sends an automated white flash every 10 seconds to help ships navigate at night or in poor visibility conditions. Access to the structure is limited, but viewing the lighthouse from nearby waters reveals the surrounding channels and island formations.

The helicopter landing pad offers visitors a unique vantage point to watch bald eagles nesting near the structure. Summer months bring whales into the surrounding waters, creating a rare wildlife viewing opportunity for those visiting the lighthouse.
