Ballenas Island Light, Lighthouse in Nanoose Bay, Canada.

Ballenas Island Light is a white octagonal concrete tower with a red gallery and lantern, standing 11 meters tall on West Ballenas Island in the Strait of Georgia. Its focal plane is 21 meters above the water, and it emits a white flash every 10 seconds with a nominal range of 17 nautical miles. The keeper's house is no longer inhabited, and the light is automated.

The first lighthouse, a square wooden tower, was erected in 1900 on the south island of the Ballenas Islands. In 1912 it was moved to the north island, where the present white octagonal tower was built in 1917. William Henry Brown served as keeper from 1901 to 1911, before the move and rebuild.

The name Ballenas Island comes from Spanish explorers who observed the marine mammals swimming nearby. Today, visitors can notice the simple red light at the top that marks the location for passing ships.

The light here is visible from about 20 miles away on clear days and helps ship captains determine their position. Since the island sits in open water, it is best visited by boat or during calm weather conditions.

Spanish explorer José María Narváez named this place in 1791 after observing numerous whales in the surrounding waters. The name has remained in use ever since, connecting the lighthouse to its maritime animal origins.
