Silhouette Island is a hidden treasure in the Seychelles, rising dramatically from the ocean just 20 kilometres off the coast of Mahé. The island is dominated by Mount Dauban, a rainforest-clad peak reaching over 750 metres, creating a rugged and untouched landscape that feels worlds apart. As the third-largest island in the archipelago, Silhouette is mostly uninhabited, with the majority of its land protected as a national park. This makes it a sanctuary for biodiversity, home to giant tortoises, endemic plants, and rare species such as the sheath-tailed bat. For travellers, Silhouette is a paradise of both relaxation and adventure. Hiking trails wind through dense rainforest, past waterfalls, and up to dramatic viewpoints. The island’s beaches, often deserted, offer postcard-perfect stretches of soft sand and turquoise water. Offshore, the surrounding Silhouette Marine National Park is ideal for diving and snorkelling, with vibrant coral reefs and excellent chances of seeing turtles and reef sharks.

Best time to go to Silhouette Island

The best time to visit Silhouette Island is April to May and October to November, when calm seas make it ideal for snorkelling, diving, and exploring the island’s reefs. These months also offer sunny weather for hiking the island’s lush trails. From May to September, trade winds bring cooler breezes, perfect for trekking into the rainforest or climbing towards Mount Dauban for panoramic views, though seas may be choppier. December to March is warmer and more humid, with occasional showers, but the island’s secluded atmosphere and unspoiled nature still make it an inviting retreat. For most travellers, the shoulder months offer the perfect balance between marine and land-based activities.

We booked our honeymoon with Viatu. From the first minute on, we had good communication going with our travel agent, and she suggested a very nice itinerary right away. After some little adjustments that were easily done, we were ready to go.
