Silhouette rises from the sea northwest of Mahé like a green cathedral — the third-largest Seychelles island and one of the least touched, a mountainous mass of ancient rainforest with barely any roads, a tiny population and one discreet resort. Named for the way its jagged peaks stand against the sunset, it is a national park almost in its entirety and a haven for species found nowhere else, from the Seychelles sheath-tailed bat to giant millipedes and rare palms.

This is the Seychelles for those who want nature over nightlife. There are no towns, no traffic and no crowds — just jungle trails climbing to misty peaks, empty beaches where turtles nest, coral reefs offshore, and a silence broken only by birdsong and surf. Most visitors come as guests of the island’s single luxury retreat or on a day trip from Mahé’s Beau Vallon; either way, Silhouette offers a glimpse of what the granitic Seychelles looked like before people arrived — a wild, primeval counterpoint to the postcard beaches.

Top Sights in Silhouette Island

The Rainforest & Peaks

The Rainforest & Peaks

Almost the entire island is protected national park — dense, mist-wrapped tropical forest climbing to Mont Dauban at 740 metres, the second-highest peak in the Seychelles. Guided trails wind up through the jungle past endemic plants, huge granite outcrops and viewpoints over the sea, into an ecosystem so intact it’s a living museum of the ancient Indian Ocean.

💡 Hike with a guide — trails are rough and unmarked in places; the forest is the whole point of Silhouette, alive with endemic species and birdsong.

The Beaches & Turtles

The Beaches & Turtles

Silhouette’s beaches are wild and near-empty — arcs of pale sand backed by forest and granite, several of them important nesting sites for hawksbill and green turtles. Anse Lascars and the beaches around the settlement are the easiest to reach; walking a deserted shore where turtles haul out to nest is a rare Seychelles privilege.

💡 Turtle nesting (roughly Oct–Feb for hawksbills) is monitored by conservationists — keep distance, no lights or flash, and go with a guide who knows the sites.

Diving & Snorkelling

Diving & Snorkelling

The waters around Silhouette are rich and relatively pristine — granite reefs, coral gardens and drop-offs with rays, turtles, reef sharks and abundant fish, plus whale sharks passing in season. The island’s resort dive centre and day-trip operators from Mahé explore sites that see far fewer divers than the busier islands.

💡 The reefs here are healthier and quieter than around Mahé — a rewarding dive or snorkel; whale sharks may appear in the Aug–Nov season.

La Passe Settlement & Conservation

La Passe Settlement & Conservation

The tiny village of La Passe, home to the island’s small community and the conservation team, is Silhouette’s only settlement — a cluster of houses, a school and the Island Conservation Society base working to protect the island’s unique species. A short walk reveals plantation-era relics and the gentle rhythm of one of the Seychelles’ last near-wild islands.

💡 Learn about the conservation work restoring the island’s endemic species — it’s central to why Silhouette matters; the settlement is a five-minute stroll.

Eating & Drinking

Silhouette has essentially one place to eat — the island’s single resort, whose restaurants serve Creole and international menus built on Seychellois seafood, tropical produce and, where possible, island-grown ingredients. There are no independent restaurants, cafes or shops to speak of, so dining is either at the resort (for its guests) or brought with you on a day trip. For guests, expect the full range from grilled fresh fish and octopus curry to fine-dining tasting menus, plus sunset cocktails with the jagged peaks behind. Day-trippers from Mahé usually come on organised boat excursions that include a barbecue lunch. It’s not a foodie destination in the sense of choice — Silhouette is about nature and seclusion — but the seafood is as fresh as the setting is wild.

A Day on Silhouette

Morning
Into the rainforest

Set off with a guide up a jungle trail through near-pristine forest — endemic plants, granite outcrops, birdsong — toward viewpoints over the sea, the wild heart of the island.

Midday
Empty beach & lunch

Descend to a deserted forest-backed beach for a swim and a barbecue lunch, the kind of turtle-nesting shore that barely exists elsewhere in the Seychelles.

Afternoon
Reefs & conservation

Snorkel or dive the healthy granite reefs offshore, then a short walk to the La Passe settlement to learn about the work protecting Silhouette’s unique species.

Evening
Peaks at sunset

For overnight guests, a sunset cocktail as the jagged silhouette that named the island darkens against the sky — total quiet, jungle behind, ocean ahead.

Travel Tips

🌴

Nature, not nightlife

Silhouette is a rainforest national park with one resort and no towns — come for hiking, wildlife and seclusion, not beaches bars or shopping.

Day trip or stay

Reach it by boat from Mahé’s Beau Vallon on an organised day trip, or as a guest of the island’s single resort — there’s no public ferry or independent lodging.

🐢

A turtle sanctuary

Hawksbill and green turtles nest on the beaches — keep well back, use no lights at night, and follow conservation-team guidance; it’s a protected privilege.

🦄

Guides for the trails

The forest paths are rough and easy to lose — hike with an island guide, who’ll also show you the endemic species that make Silhouette special.

💰

Few options, plan ahead

With one resort and no shops, day-trippers should bring what they need and book excursions in advance; staying is a luxury proposition.

🌿

A living time capsule

Silhouette shows the granitic Seychelles as it was before humans — tread lightly, take nothing, and leave the wildest inner island as you found it.

Useful Apps

Silhouette is a wild national-park island — arrange everything (day trips, transfers, stays) in advance; there’s minimal connectivity and no ride-hailing.
