The Aldabra Atoll, a UNESCO World Heritage site, is the most remote of Seychelles’ 115 islands. It shelters one of the planet’s largest populations of giant tortoises—more than 150,000 individuals—alongside the western Indian Ocean’s biggest green turtle breeding colonies. The Seychelles archipelago is one of only two places on Earth where granite islands appear in the middle of an ocean, and the Outer Islands, called Zil Elwannyen Sesel in local Creole, offer a completely different geological and ecological experience from the granite Inner Islands where 98 percent of Seychellois live.
Astove Atoll, 647 miles and two plane rides from Mahé, is closer to Madagascar than to Victoria, the capital of Seychelles.
This article covers the practical realities of reaching these far-flung islands—distance, cost access limits—and what you actually find when you get there: abandoned copra plantations, fossilized coral reefs, and conservation programs that tag manta rays and sharks. It also covers the less-visited granite-island beaches that require a hike or a resort booking to reach. The distinction matters because the Outer Islands operate under a “one island, one resort” policy, and the logistics for each are completely different.
If you want real remoteness—the kind where a ghost yacht sits beached on a shoreline and the next plane is days away—head to the Outer Islands. But getting there takes two flights, significant expense, and advance booking through a single operator like Blue Safari. If you want off-the-beaten-path within reach of Mahé, the granite-island beaches like Anse Marron on La Digue or Anse Georgette on Praslin deliver isolation without the logistical ordeal.
Inner Islands vs. Outer Islands: Understanding Seychelles’ Two Worlds
The 43 Inner Islands—Mahé, Praslin, La Digue, and their smaller neighbors—constitute about 175 square miles of land surrounded by roughly 529,000 square miles of ocean territory. Nearly all visitors stay here, and the infrastructure is well-developed. The Outer Islands—72 coral atolls and sand cays divided into five geographical groups, including the Amirantes and Farquhar—are another world entirely. Only two percent of Seychellois live there.
Distance from Mahé to Astove Atoll, one of the farthest south of the Outer Islands, requiring two plane rides.
Traveller types diverge sharply here. The Inner Islands suit anyone who wants a mix of accessible trails, marine parks, and resort beaches with the option to walk in without pre-booking. The Outer Islands are for divers, fly fishermen, and people who consider a multi-day journey to an atoll with no permanent structures a feature, not a bug. Astove Atoll—a tiny atoll with an abandoned copra plantation, an eight-square-mile lagoon, and sharp blades of fossilized coral called champignon—is about as far from a resort holiday as Seychelles gets. The Cheval Blanc Seychelles hotel opened in 2024, but it sits on a completely different island (Platte) from the raw Outer Island experience.
Granite-Island Seclusion: Beaches That Require Effort
On Mahé, Praslin, and La Digue, the most secluded beaches are the ones you cannot simply drive to.
Anse Georgette, Praslin
Anse Georgette sits on Praslin’s northwestern coast, hemmed in by granite boulders and casuarina trees. Access requires either a pre-booked visit through the Constance Lémuria Resort or a hike from the public road. The resort allows non-guests to visit, but you must call ahead or book online—same-day walk-ins are turned away. The path from the road takes about 20 minutes through coastal forest, and the beach itself is exposed to swell; swimming conditions vary significantly with the monsoon.
Anse Marron, La Digue
Anse Marron is not signposted, not on the main bike route, and not reachable by footpath alone. It requires a guided hike through dense jungle and over granite rocks. The payoff is a natural pool protected by boulders where the water stays calm even when the outer reef is rough. Guided tours from La Digue’s main settlement cost around SCR 500–700 per person and take about two hours round-trip. The hike involves scrambling over boulders; sturdy footwear is necessary, and the path can be slippery after rain.
Fond Ferdinand Nature Reserve, Praslin
Fond Ferdinand is Praslin’s less-visited alternative to the Vallée de Mai, featuring endemic Coco de Mer palms in their natural habitat. The reserve charges a lower entry fee than Vallée de Mai and sees a fraction of the visitors. A guided walk takes about 90 minutes and ends at a viewpoint with panoramic views over the coast. The trail is uphill and uneven; guides carry a water bottle for you, but bring your own. The Coco de Mer palms here are less concentrated than in Vallée de Mai, but the overall experience feels more like a genuine forest walk and less like a botanical garden.
Morne Seychellois National Park on Mahé contains trails to the Ros Sodyer waterfall and the Congo Rouge trail. The Congo Rouge trail is a 3.5-hour loop through the park’s highest elevations, offering views over Victoria and the east coast. The Ros Sodyer trail is shorter—about 1.5 hours—and ends at a waterfall that flows year-round but is strongest after the northwest monsoon (December to March).
Practical Planning: Getting There, Timing, and Costs
The Outer Islands require a completely different planning approach than the Inner Islands. Here is how the logistics compare.
| Factor | Inner Islands | Outer Islands |
|---|---|---|
| Transport | Ferries, domestic flights, rental cars | 2 flights from Mahé via small aircraft |
| Accommodation range | Self-catering to luxury resorts | Single eco-lodge or camp per island |
| Booking flexibility | Walk-in or book days ahead | Weeks or months in advance required |
| Cost per night | USD 100–1,500 | USD 800–3,500 (all-inclusive, multi-night packages) |
Getting There
For the Inner Islands, Air Seychelles and IDC (Island Development Company) operate domestic flights between Mahé, Praslin, and La Digue. The ferry from Mahé to Praslin takes about an hour; from Praslin to La Digue, 15 minutes. For the Outer Islands, Blue Safari, founded in 2012 by Murray Collins and Keith Rose-Innes, manages the only accommodation on Alphonse Island—the 29-key Alphonse Island Lodge—and sets up temporary eco-pod rooms on Cosmoledo, elegantly converted shipping containers and research-style camp tents designed to be disassembled with little trace. Blue Safari also runs trips to Astove. Flights to Alphonse depart from Mahé once daily, weather permitting.
Astove’s lagoon contains sharp blades of fossilized coral called champignon. Walking on the reef flat without reef shoes can result in deep cuts. The same coral formations are present on Cosmoledo and Aldabra. Local guides will warn you, but the cuts happen anyway.
Best Time to Visit
The southeast monsoon (May to October) brings stronger winds, rougher seas, and clearer skies. The northwest monsoon (November to April) is calmer and wetter, with higher humidity and more afternoon rain. For the Outer Islands, the southeast monsoon offers better diving visibility and less rain, but the crossing from Mahé to Alphonse or Astove can be bumpy. Bird Island is at its most dramatic during the sooty tern breeding season (May to September), when millions of birds nest on the island. For the Inner Islands’ secluded beaches, the northwest monsoon provides calmer swimming conditions at exposed beaches like Anse Georgette and Petite Anse.
Costs and Fees
Seychelles has the highest GDP per capita in Africa, and prices reflect that. Park entry fees for Morne Seychellois National Park and Fond Ferdinand Nature Reserve are modest—SCR 100–300—but Outer Island packages start at around USD 800 per person per night and climb steeply. The Blue Bond launched by Seychelles in 2018 raised $15 million from global investors and committed the country to protect 30 percent of its waters, 162,000 square miles. That conservation framework affects access: some Outer Islands limit visitor numbers to reduce environmental impact. Aldabra Atoll, home to one of the largest green turtle breeding populations in the western Indian Ocean, requires significant planning and permits to visit.
On the Ground: What to Pack, Eat, and Know
The practical realities of Seychelles travel—especially to the Outer Islands—differ from what most visitors expect from an Indian Ocean destination.
Packing for Two Worlds
For the Inner Islands, a daypack with water, reef shoes, and a rain jacket covers most situations. The trails in Mahé’s national parks are steep and humid; you will sweat through a shirt within 15 minutes. For the Outer Islands, you need a duffel bag—not a wheeled suitcase—because the small aircraft that fly to Alphonse and Astove have strict weight limits (typically 15–20 kg per person) and no cargo hold large enough for rigid luggage. A compact drone like the DJI Mini 3 Fly More Combo fits within the weight limit and captures the scale of the Outer Islands’ lagoons in a way a GoPro cannot. The built-in screen on the controller is bright enough to see in direct sunlight, which matters when you are standing on a white-sand beach with no shade.

Food and Water
The farm at Alphonse Island Lodge is roughly 430,000 square feet and produces four tons of crops a month, supplying up to 90 percent of plant-based food across all of Blue Safari’s accommodations in the Outer Islands. The farm also produces over half a ton of fertilizer every week from composting. Blue Safari sources fish only from the open ocean, never the reef. On the Inner Islands, Sir Selwyn Selwyn-Clarke Market in Victoria is where locals buy fresh produce and fish; it is open Tuesday to Saturday mornings and is the best place to see what Seychellois actually eat—jackfruit, breadfruit, octopus, and a reef fish called bourzwa. Restaurants on Praslin and La Digue often run out of popular dishes by 7 p.m.; eating early is the norm.
Local Customs and Etiquette
Seychellois society is a mix of African, European, and Asian influences, and the pace of life is slow. Meals are taken seriously; lunch often runs from noon to 2 p.m., and many small shops close during that window. On La Digue, bicycles are the primary mode of transport, and locals expect cyclists to ring a bell or call out before passing—it is considered rude to pass silently. On the Outer Islands, tipping is not expected but appreciated; USD 5–10 per day for lodge staff is standard. The local currency is the Seychellois rupee (SCR), but euros and US dollars are widely accepted at hotels and tour operators. Small shops and market stalls prefer rupees.
- For the Outer Islands, book through a single operator like Blue Safari and commit to one atoll for the entire stay—island-hopping is not an option.
- Pack a duffel bag, not a suitcase, for Outer Island flights; weight limits are strict and rigid luggage does not fit the aircraft.
- Eat dinner early on Praslin and La Digue—popular dishes run out by 7 p.m., and kitchens close earlier than in Mahé.
Frequently Asked Questions About Seychelles’ Remote Islands
Can I visit Aldabra Atoll without a research permit?
Technically yes, but practically no. Aldabra is a UNESCO World Heritage site with restricted access. The only way to visit is through a pre-arranged expedition or a stay on a liveaboard. The Aldabra Group includes Astove, which is easier to reach through Blue Safari, but Aldabra itself requires significant advance planning and government permission.
The tradeoff is that Aldabra is home to more than 150,000 giant tortoises and one of the largest green turtle breeding populations in the western Indian Ocean. If you are determined to see it, start planning at least six months ahead and expect to pay several thousand dollars for a multi-day trip.
Is Anse Georgette worth the hassle of pre-booking?
Yes, but only if you time it right. The beach faces northwest, so the southeast monsoon (May to October) brings stronger waves and less calm water. During the northwest monsoon (November to April), the water is calmer and the beach is at its best. The pre-booking requirement through Constance Lémuria Resort is straightforward—call or email a day ahead—but if you arrive without a booking, you will be turned away.
What most visitors do not realize is that the hike from the public road takes about 20 minutes through coastal forest and is flat the entire way. The harder part is finding the trailhead; it is not signposted from the main road.
How do the Outer Islands compare to the Maldives for remoteness?
The Outer Islands feel more remote because fewer people go there. The Maldives has over 1,000 resorts spread across 26 atolls; Seychelles’ Outer Islands have a handful of lodges and a strict “one island, one resort” policy. On Cosmoledo, Blue Safari’s eco-pod rooms—converted shipping containers and camp tents—are designed to be disassembled with little trace. There are no overwater villas, no spa menus, no gift shops.
The downside is that the Outer Islands lack the infrastructure that makes the Maldives easy. Flights are weather-dependent, medical evacuation is complicated, and you cannot decide to change islands mid-trip. If you want remoteness with a safety net, stick to the Inner Islands’ less-visited beaches.
What is the best way to see giant tortoises in Seychelles?
The easiest place is Bird Island, where giant tortoises roam freely around the lodge and airstrip. You can walk up to them—slowly—and photograph them without barriers. Cousine Island also has tortoises, but access is highly restricted and typically requires a stay at its exclusive eco-lodge. Fregate Island runs a giant tortoise breeding program alongside recovery efforts for the Seychelles Magpie Robin.
The tradeoff is that Bird Island’s tortoises are habituated to human presence, so the experience feels more like a zoo encounter than a wild one. For wild tortoises in their natural habitat, you need to go to Aldabra—but that requires the planning and cost mentioned above.
Are there any hidden costs I should expect?
Yes, several. Park entry fees for Morne Seychellois National Park and Fond Ferdinand Nature Reserve are modest, but guided hikes at Anse Marron on La Digue cost SCR 500–700 per person and are cash-only. Domestic flights to Praslin and La Digue are cheap—around USD 50 one-way—but Outer Island flights are not included in lodge packages and cost USD 400–600 round-trip per person.
The biggest hidden cost is the 15–20 kg baggage limit on Outer Island flights. Excess baggage is charged at roughly USD 5 per kilogram, and the fee adds up fast if you bring scuba gear or camera equipment. Turtle watching on pristine beaches requires no extra fee, but getting to those beaches often does.
The Outer Islands are not a better version of the Inner Islands—they are a completely different category of travel. The Inner Islands offer accessible seclusion: beaches you can reach by footpath or bike, trails through national parks, and the option to change plans daily. The Outer Islands offer a commitment: one atoll, one lodge, one rhythm of life dictated by tides and flight schedules. Choosing between them is not about budget or time alone—it is about whether you want the freedom to move or the discipline of staying still. For most travellers, the granite-island beaches of Mahé, Praslin, and La Digue provide enough isolation without the logistical burden. But for those who want to see where the Seychelles archipelago extends into the open Indian Ocean, the Outer Islands chart a course that few visitors take.
