Indulging in Diving on Denis Private Island, Seychelles

A pinprick of land not even 2 miles long, Denis Private Island introduces itself quietly through the rustle of takamaka trees, birdsong calling in the distance and gentle waves lapping the shores.

This isn’t some Insta-perfect resort. It’s the real deal—a place where nature hasn’t been bulldozed for the sake of luxury, a place where the ocean still calls the shots.

In the Seychelles archipelago, where turquoise waters meet powder-soft beaches, Denis Private Island stands out not just for its raw beauty, but for its extraordinary second act.

Reclaimed by Nature

Like many islands in the Seychelles, Denis was stripped of native vegetation for coconut plantations in the 1800s. But over the past two decades, it has undergone a quiet revolution thanks to owners who are driven by a vision of restoration rather than exploitation, rewilding the land and declaring the surrounding waters a marine protected area. Their reforestation program has systematically replaced non-native palms with endemic species, and an aggressive eradication of invasive rats, cats and Myna birds has allowed native species to flourish. The result? An island that feels like stepping into the Seychelles of 50 years ago.

Here, sustainability goes beyond conservation to create a near-perfect closed loop. The resort is powered entirely by solar energy and grows most of its food organically while repurposing all waste.

Meanwhile, the 22 cottages and single beach villa are refined yet laidback, made of reclaimed timber and local stone with framed panoramic sea views in a palette of blues so mesmerizing you might think it’s AI-generated. The allure continues inside thanks to vaulted ceilings that catch the trade winds, billowing linens that flutter like sails, deep verandas where you can lose an afternoon while palms sway hypnotically around you. The crown jewel is the Beach Villa, which features a private plunge pool, al fresco showers and an outdoor dining pavilion for meals under a chandelier of stars.

Spirited Indulgence

The island’s chefs vie for attention in the kitchen, turning just-picked produce and line-caught fish into meals that capture the spirit of the Seychelles. Breakfast might be ripe mango and passion-fruit plucked from the garden, eggs from free-roaming hens and cinnamon crepes drizzled with local honey. Lunch is a breezy affair of grilled octopus salad or coconut curry served in the shade of a takamaka tree. Come evening, the mood shifts and guests might choose to sit at candlelit tables in the sand. As waves sigh against the shore, the sommelier will pour South African Chenin Blanc as the first stars appear, served with perfectly seared tuna crusted in island-grown peppercorns. The staff can even arrange a private feast on a sandbank at low tide.

Luxury here is having freedom to spend your day doing nothing at all—or to not miss a thing. You might start with a massage in the open-air spa, then drift into a hammock with a novel until the urge to move strikes again. When it does, the options are plenty: a snorkel through coral gardens, a kayak paddle along the lagoon, a bike ride down jungle paths.

Diving Into Another World

Beneath the waves, the conservation story continues. As part of a newly designated marine protected area, Denis has become a sanctuary for marine life. Hydrophones monitor passing whales while a strict tag-and-release policy protects billfish populations. The island's beaches now host approximately 420 sea turtle nests annually, about 150 from endangered hawksbills and 270 from green turtles, making it one of the region's most important nesting sites.

The reef's seagrass meadows swarm with juvenile fish, and seemingly every nook in the rocks shelter moray eels and octopuses. And unlike the more famous dive sites of the Seychelles, Denis’ reefs remain surprisingly untouched. There are no crowds, no queues of divers waiting to descend. Instead, there is only the vast, shimmering expanse of the Indian Ocean.

Imagine hopping aboard a dive boat at first light to encounter an ocean so calm it reminds you of wet glass. As you motor out, the world shrinks to just water and sky with no land in sight—that perfect, endless blue. Then you slink below the surface and the bottom seemingly disappears beneath you, dropping away into a deep, dark nothing. Suddenly, a shadow emerges: It’s a manta ray with a wingspan of nearly 13 feet, and it soars past with effortless grace. It circles once, twice, then vanishes back into the deep.

The resort's guest cottages, made from reclaimed timber, are elegant while maintaining the breezy laid-back island vibes.

Diving here changes with the rhythms of the ocean. From October to November, the water hums with movement as whale sharks and manta rays pass through. By November, the currents shift, bringing crystalline visibility that lasts until May. The windier months (May to September) can churn the sea, but they also bring solitude—divers willing to brave the conditions often find themselves alone with the ocean’s inhabitants.

The true magic of Denis Island is that it sticks with you long after the dive gear has been packed away. It’s the quiet rhythm of the island that lingers, with no activity schedules, no contrived experiences. Just nature calling the shots. In an age of overtourism and vanishing wilderness, that is something worth preserving and celebrating.
