This British island has Caribbean-blue waters and 340-year-old secrets (locals say visitors check their GPS when they arrive)

Saint Martin’s Island: Britain’s Secret Subtropical Paradise Where Caribbean-Blue Waters Meet Ancient History

A hidden gem with azure surprises

Just 28 miles off Cornwall’s coast lies Saint Martin’s Island, home to what many travelers mistake for a Mediterranean mirage: impossibly white sand beaches washed by turquoise waters that could rival the Caribbean. This smallest inhabited island in the Scilly archipelago (population: 120) harbors a secret – it boasts England’s most stunning beaches despite being closer to London than Barcelona.

On Great Bay’s pristine shoreline, the Atlantic transforms into an improbable aquamarine mirror that reflects England’s sunniest microclimate. One local boat captain told me:

“Visitors often check their GPS when they first see our waters. They simply can’t believe these colors exist in British territory.”

The 340-year-old beacon with panoramic rewards

Ascending the heather-lined path to Burnt Hill reveals the island’s most iconic landmark – the Daymark, a distinctive red and white striped navigation tower erected in 1683. This historic beacon offers panoramic views that stretch across the archipelago’s patchwork of islands and islets scattered across the azure Atlantic.

The 20-minute hike rewards visitors with more than just views. Wildlife enthusiasts might spot peregrine falcons or the rare Scilly shrew along the coastal heathland.

Swim with wild Atlantic grey seals

Perhaps the most extraordinary experience awaits at aptly-named Seal Cove, where visitors can snorkel alongside curious Atlantic grey seals in crystal-clear waters. Unlike orchestrated wildlife encounters elsewhere, these interactions happen organically as the playful mammals investigate human visitors.

While not quite as geologically dramatic as the Philippines’ volcanic wonders, the underwater landscapes here feature dramatic rock formations and swaying kelp forests teeming with marine life.

Britain’s most unexpected vineyards

Thanks to its subtropical microclimate, Saint Martin’s hosts the northernmost commercial vineyard in Britain. St. Martin’s Vineyard cultivates German and French varietals that thrive in this unlikely terroir. The vineyard’s owner explained:

“The Gulf Stream creates our unique growing conditions – we’re essentially farming in a microclimate that shouldn’t exist at this latitude.”

Visitors can sample these improbable vintages while gazing across palm trees toward the Atlantic – a surreal juxtaposition that feels more Mediterranean than British.

Historical islands frozen in time

Beyond Saint Martin’s shores lie uninhabited islands with fascinating histories. Nornour contains the remarkably preserved ruins of an ancient settlement where Roman artifacts mingle with prehistoric remains. While not as extensive as Peru’s ancient Inca ruins, these archaeological sites offer a profound connection to Britain’s distant past.

Artisanal island life

The island’s Higher Town hosts a collection of artisanal producers creating distinctly Scillonian products. The Island Bakery produces legendary Cornish pasties, while Scilly Flowers cultivates fragrant blooms that reach London markets hours-fresh thanks to daily flights.

Much like hidden Caribbean destinations, Saint Martin’s has managed to preserve its authentic character while accommodating discerning travelers.

Getting there: The journey is part of the adventure

Reaching Saint Martin’s requires determination – first flying to St. Mary’s (from Exeter, Newquay or Land’s End) or sailing aboard the Scillonian III from Penzance, then catching a small boat transfer. This deliberate isolation has preserved the island’s untouched character.

As a local fisherman told me:

“The effort it takes to reach us is our best protection. Only people who truly want to be here make the journey.”

Unlike Sydney’s accessible harbor attractions or colorful Arctic capitals, Saint Martin’s reward is pristine solitude and nature’s untouched rhythms.

Standing on Great Bay as sunset transforms the Atlantic into liquid gold, it’s impossible to believe you’re still in Britain. In this hidden corner of England, the Caribbean seems to have drifted north, bringing its colors but leaving behind the crowds – perhaps the most precious discovery of all.
