Montague Harbour Marine Provincial Park, Marine provincial park in Galiano Island, Canada

Montague Harbour Marine Provincial Park occupies a peninsula on Galiano Island's west side, about 6 km from the Sturdies Bay ferry terminal. The park lies in the Capital Regional District of British Columbia, 36 metres above sea level, and is reached by BC Ferries from Swartz Bay or Tsawwassen. Its surroundings are mainly mixed forest, with flat terrain to the northwest and hilly ground to the south.

People first settled on Gray Peninsula more than 3,000 years ago, as shown by archaeological finds from those early times. European explorers arrived much later in 1791, marking a later chapter in the area's story.

The park lies on Galiano Island, homeland of the Penelakut and other Coast Salish peoples, whose shell middens lie in the northern section. Visitors can see these deposits along the Gray Peninsula shoreline, where centuries of harvesting shellfish, fishing and camping left layers of shell and soil.

The park provides campsites accessible by vehicle and on foot, along with picnic areas and restroom facilities for visitors. Full services are available during the warmer months when conditions are most favorable for camping and outdoor activities.

This location holds the distinction of being the first marine protected area in British Columbia and provides shelter to more than 130 bird species throughout the year. Birdwatchers find this diversity particularly rewarding to observe across the seasons.
