Swimming With Sperm Whales in Dominica: What Has Changed

Dominica created the world's first sperm whale reserve, roughly 300 square miles of protected water off the west coast. Several hundred whales live here in tight family groups, matrilineal societies of grandmothers, mothers and daughters that stay together for life and that researchers have tracked individually for years.

Unusually, they do not really leave. Most sperm whale populations range across whole oceans. Dominica's stay close to the island year-round, which is the reason encounters here are possible at all.

The rules have tightened considerably. In-water encounters are capped at ten minutes. The number of boats permitted on the water is limited, crews must be certified, and operators cannot put snorkellers in the water near nursing calves. Only one group may observe sleeping whales. Holders of recreational permits are also barred from publishing images of swimmers and whales together, so a great deal of what you have seen online no longer reflects what is actually on offer.

None of this makes the experience worse. It makes it rarer, quieter, and considerably better for the whales.

What it does mean is managing expectations. Book through a licensed operator. Build in more than one day if this is the reason you are coming. Expect to be told no when conditions or regulations require it, and treat any sighting as a privilege rather than a purchase.

The reserve sits off our side of the island, which makes an early start a good deal easier.
