Champagne Reef
Depth is the range from the top of the site to its usual maximum; "recommended cert" is the mainstream-agency level operators usually ask for, not a legal rule. Currents and visibility change daily — treat everything here as planning ranges.
At Champagne, Dominica's volcano exhales through the seabed. Streams of warm bubbles rise from vents among the boulders, wobbling toward the surface in silver columns that divers swim through like weather, and patches of sand nearby run noticeably warm to the touch. The novelty draws the crowds, but the reef holds attention on its own terms: sponges crust the volcanic stone, juvenile fish shelter in the cobble, and the seagrass edge turns up seahorses, flying gurnards, and hunting squid. Shallow, warm, and endlessly strange, it suits snorkelers and photographers as much as divers.
The moment you come for: Swimming through volcanic bubble streams, warm vents, seahorse hunting on the margins
Topography: Volcanic boulders and cobble venting streams of geothermal gas
Entry: A boardwalk from the shore drops snorkelers and divers directly over the bubble field; boats also visit from Roseau.
Know before you splash
Hazards: Vent stones and sand can be hot to the touch; cruise-day snorkel crowds thin by late afternoon.
Permits & rules: Lies within the Soufriere-Scott's Head Marine Reserve; a small user fee applies.
