Here’s an old Times Colonist aerial photo Mitch Lindsay dug up of Cadboro Bay in the early 1950s:

Apparently the proposed boundaries of the new Gyro Park back then included the blue cottage at D-3905 Cadboro Bay Road. In the end, D-3905 Cadboro Bay Road was not acquired for the new Gyro Park, which may explain why the property was left to this day without road access.
The building on the lower left is the old Tea Caddy tea house. I believe the house to the right was the Egan residence.
