The Whale Trail
Cotton Park, Mayne Island

JASCO has collaborated with the Vancouver Aquarium to bring you the following marine mammal vocalizations. The Land-Based Whale Watching project, known as The Whale Trail, is an initiative that supports on-shore locations from which the public can see orcas and other marine mammals and report their sightings to the B.C. Cetacean Sightings Network.
