On the wild East End coast, the sea has drilled chimneys through the limestone shelf. When the swell arrives, the shore erupts.
Centuries of swell have carved tunnels up through the ironshore shelf along the East End coast. When waves drive in, trapped air and water blast through the openings in hissing plumes that can reach several metres on a good day, each eruption announced by a sound like the island exhaling.
The blowholes perform on the sea\u2019s schedule: an onshore swell makes the show, a flat calm cancels it. Winter months and windy days are the safest bets. Photographers should shoot into the light in late afternoon, when the spray turns gold.
The stop is free and roadside on the coast road, ten minutes from the East End resorts. Fold it into the island loop with Pedro St. James and the Botanic Park, and keep respectful distance from the wet rock: the same physics that makes the plumes has claimed phones and worse.
On the Frank Sound coast road toward East End, marked and free to visit from the roadside. Allow fifteen minutes plus photo time.
With an onshore swell, typically on windier winter days. In flat calm summer conditions the show can pause entirely.
