The Lighthouse on Trial Island at the entrance to Victoria Harbour was constructed in 1906.
The long, narrow island is separated from the shore at the end of Marine Drive by only a short distance. The lighthouse can be viewed in the distance from the shore.

When British naval vessels were refitted at Esquimalt Harbour they were sailed to an island just off of Oak Bay and then sailed back, completing a trial run. Thus the island was eventually given the name ’Trial Island’. Enterprise Channel is the narrow (300 feet) body of water that lies between Oak Bay and Trial Island that is known to be treacherous because it has strong tide races.
