When possible, the best and most resposible way to view whales and marine wildlife is from land whereby there is no human impact. There are various locations across the BC coast where viewing whales from land is possible, many of which have been included as part of the British Columbia Whale Trail (more information can be found here https://thewhaletrail.org/regions/british-columbia/). While on the water, it is crucial to be aware of the minimum approach regulations to all marine mammal species, which are specified by the Department of Fisheries and Oceans Canada, and can be found here https://www.dfo-mpo.gc.ca/species-especes/mammals-mammiferes/watching-observation/index-eng.html
