Whale watching is the practice of observing whales and other cetaceans in their natural habitat. Whales are watched most commonly for recreation (cf. birdwatching) but the activity can also be for scientific or educational reasons. Whilst individuals do organize private trips, whale watching is primarily a commercial activity, estimated to be worth up to $1billion per annum worldwide to whale watching operations and their local communities. The size and rapid growth of the whale watching industry has led to complex and unconcluded debates with the whaling industry about the best use of whales as a natural resource.
Whale watching as an organized activity dates back to 1950 when the Cabrillo National Monument in San Diego was declared a public spot for the observation of gray whales. In 1955 the first water-based whale watching commenced in the same area, charging customers $1 per trip to view the whales at closer quarters. The spectacle proved popular, attracting 10,000 visitors in its first year and many more in subsequent years. The industry spread throughout the western coast of the United States over the following decade.
Whale watching today is carried out from the water from crafts from kayaks, motorized rafts, and sailboats through to out-of-use fish or whaling boats and custom-built craft carrying as many as 400 people. Land-based watching of species such as the orca who come very close to shore remains popular. Viewing of species that usually stay some distance from the shore is also offered by fixed-wing aircraft or helicopters in some areas.
