The Teno-Rasca Marine Conservation Zone, situated off the western coast of Tenerife, Spain, encompasses approximately 70,000 hectares of protected ocean. This unique sanctuary is home to resident populations of pilot whales and bottlenose dolphins, as well as migratory species and several types of sea turtles. In theory, strict regulations prohibit swimming with or chasing whales and dolphins, feeding them, and limit the number of boats allowed near pods. In practice, enforcement remains weak. Earlier this year, seven tourists were fined after jumping from a boat to interact with pilot whales — a clear violation of the rules.
Meanwhile, jet skis, speedboats, and unauthorised tour operators continue to approach marine wildlife at high speed, disrupting natural feeding and resting behaviour. Some illegal businesses openly offer kayak and snorkelling trips with dolphins and turtles for as little as €40. Licensed whale-watching operators are required to display a “Blue Boat” flag, but authorities acknowledge that inspections and sanctions are sporadic. The surveillance vessel Mar Canario, purchased in 2019 to patrol protected waters, has reportedly been absent during the main summer tourist months.
Tenerife’s whale sanctuary is unique, fragile, and worth protecting — but without consistent monitoring and meaningful enforcement, its future remains uncertain.
