A Day at Sea: Snorkeling Isla Coronados and the Wild Heart of Loreto Bay
Four hours of snorkeling, sea lions and volcanic coastlines—family-friendly and easy to book
You step off the boat onto sugar-white sand and the first thing that hits you is the color — water so improbably turquoise it looks like someone painted the horizon. A gull calls from the craggy rim of a volcanic spire and a sea lion bobs nearby, curious but polite. For four hours, the world compresses into that shoreline: the island’s basalt ribs, schools of shimmering fish, and a wind that seems to breathe history and salt. This is Isla Coronados — a compact, volcanic outcrop in the protected Loreto Bay National Park — and a guided trip here trades in easy spectacle and purposeful quiet: equal parts snorkeling playground and a lesson in why the Sea of Cortez earned the nickname “the Aquarium of the World.”
Trail Wisdom
Bring reef-safe sunscreen
Protect skin and coral: choose a mineral sunscreen labeled reef-safe and reapply after snorkeling.
Arrive early
Check-in at the marina by 8:50 a.m. to ensure timely departure and a good spot on the boat.
Rent a wetsuit if sensitive to cold
Wetsuits are available locally (about $10) and can make snorkeling comfortable outside peak summer months.
Pack a small dry bag
Keep phone, cash and a light jacket dry and handy while on the water.
