About Sisters Islets Lighthouse

A narrow, round, cylindrical concrete tower, painted white and measuring 18 meters in height, stands on a small island west of Lasqueti Island. The tower, which flares at the top and is topped with a red lantern and gallery, was first lit in 1967. Its focal height reaches 21 meters, casting a white light with one flash every 15 seconds. This light has a geographic range of 13.4 nautical miles. The Sisters Islets Lighthouse was automated in 1996. It is located approximately 15 kilometers north of Qualicum Beach and about 13.8 kilometers from Texada Island.

Why it matters: This lighthouse guides vessels through the passage between Lasqueti Island and Hornby Island. The structure's design evolution from an earlier 1898 station to the current 1967 tower reflects changes in lighthouse architecture and operation.
