The Sister Islands (Grande Soeur & Petite Soeur),Seychelles

Grande Soeur and Petite Soeur (literally “big sister” and “little sister” in French) are two granite islets lying just off the northwestern tip of La Digue in the Inner Islands of the Seychelles. They are valued for their near-pristine beaches, classic granite boulder scenery typical of the Seychelles, and important coastal and marine ecosystems. Grande Soeur hosts limited private accommodation and managed visitor access while Petite Soeur is largely undeveloped and valued as a quiet nature refuge. The islands contribute to local biodiversity (seabirds, reef fish, corals) and are part of the broader conservation and low-impact tourism model used across the Inner Islands.

Places to visit

Pristine white-sand beaches framed by iconic granite boulders
Crystal-clear snorkeling waters and coral gardens around both islands
Secluded shorelines ideal for swimming, sunbathing and photography
Small-scale accommodation and private- island hospitality on Grande Soeur (limited availability)
Uninhabited, tranquil environment on Petite Soeur — great for nature observation and quiet exploration
Short boat trips from La Digue with panoramic views of the Le Morne area and northern reefs

Unique Aspects

Distinctive Seychelles granite rock formations and sculpted boulders
Shallow coral reefs and rich snorkeling/diving sites
Seabird and coastal marine habitats — peaceful nature refuge on Petite Soeur
Very low visitor numbers compared with more accessible islands — strong sense of privacy and seclusion
Picturesque viewpoints for sunrise/sunset and excellent photo opportunities

Things to do

Snorkeling and shallow-water reef exploration (bring or rent gear)
Swimming and relaxing on near-deserted beaches
Short guided walks/explorations of the shoreline and boulder areas
Bird- and marine-life spotting from shore or boat
Photography — classic Seychelles landscapes without the crowds
Private events or intimate beach weddings (by prior arrangement)

Best Time to Visit

Seychelles is broadly year-round but the best windows for calm seas and easy snorkeling are April–May and October–November (transitional periods). Trade winds influence conditions: typically stronger southeast winds May–September and northeasterlies October–March.

Weather Conditions

Tropical maritime climate: warm year-round with daytime temperatures commonly 24–32°C (75–90°F). Humidity is moderate to high; brief, sometimes heavy showers can occur year-round.

Accessibility

Access is by boat only. The usual gateway is La Digue (short speedboat or traditional pirogue ride). La Digue itself is reached by ferry from Praslin or Mahé. There are no airstrips; on-island facilities are minimal, so plan logistics from La Digue.

Recommended Duration

Day trips are common (half- to full-day). If staying on Grande Soeur is possible (very limited accommodation), allow 1–2 nights to enjoy the solitude and sunsets.

Clothing & Gear Tips

Light, breathable clothing; strong reef shoes for rocky shore entries; snorkel mask + fins (if you prefer your own); sun protection (reef-safe sunscreen, hat, sunglasses); a waterproof bag for electronics; insect repellent for dusk.

Local Food & Souvenirs

Grande Soeur may offer limited meals for private-stay guests — otherwise plan snacks or meals through your operator. Nearby La Digue offers local Seychellois dishes (grilled and curried fish, coconut-based preparations, tropical fruit) and handcrafted souvenirs. Respect all rules on shell collection — many species and items are protected.
