Coco Island: A Hidden Gem in Seychelles

Coco Island sits about a 45-minute boat ride from Praslin, a speck of granite and sand that barely registers on a map of Seychelles. What it lacks in size it makes up for in concentrated marine life — the shallow waters around the island hold coral formations that draw snorkelers back year after year.

This guide covers what to expect on a Coco Island excursion — the snorkeling conditions, how to combine it with nearby spots like Curieuse and St. Pierre, and the practical realities of visiting a tiny uninhabited island with no facilities. If you’re planning a day on the water around Praslin, this is the honest picture of what that looks like.

Where Coco Island fits in a Praslin itinerary

Most visitors base themselves on Praslin and take a full-day boat trip that strings together three or four islands in the area.

Coco Island is typically paired with Curieuse Island — home to giant tortoises — and the sandbank at St. Pierre, another snorkeling spot. The standard loop takes around six to seven hours, with roughly 45 minutes to an hour at each stop. Coco is usually the first or second drop, depending on wind direction and the skipper’s preference.

The island itself is a bare granite outcrop with a fringe of white sand. No shade, no toilets, no food stalls. What you get is water access and coral. That’s it. For families, that means packing everything you’ll need for the stop — water, snacks, reef shoes, and a reef-safe mineral sunscreen that won’t wash off in the first five minutes.

Snorkeling Coco Island — what the water actually looks like

The reef wraps around the southern and eastern sides of the island, and the water clarity depends heavily on swell and recent weather.

On a calm day, visibility can reach 15 to 20 metres. You’ll see table corals, brain corals, and clusters of branching Acropora. Fish life includes parrotfish, sergeant majors, triggerfish, and the occasional turtle cruising the edge of the reef. The current can pick up around the point, so it’s worth keeping an eye on where the boat is anchored.

One limitation: the reef is shallow — in places, the coral comes within a metre of the surface. That makes it excellent for snorkelers who don’t want to dive deep, but it also means fins can kick and damage the coral if you’re not careful. Seychelles’ underwater world is fragile, and guides remind visitors to float rather than stand.

St. Pierre — the sandbank alternative

St. Pierre is a small granite islet about 20 minutes from Coco by boat. It’s essentially a sandbank with a cluster of boulders, and the snorkeling here is different — deeper water, bigger fish, and stronger currents. The coral is less dense than Coco, but you’re more likely to see reef sharks and rays cruising the sandy channels between rocks.

Most tours stop at both, which gives you two distinct underwater environments in one morning. If you’re travelling with kids who are less confident in the water, Coco’s shallows are the safer bet. St. Pierre requires better buoyancy control and a willingness to drift with the current back to the boat.

Planning your Coco Island excursion

Boat tours depart from Praslin’s main jetty near Baie Sainte Anne, and most operators run the same basic route with minor variations.

The standard price for a full-day shared tour ranges from €80 to €120 per person, depending on the operator and whether lunch is included. Private charters cost more — typically €400 to €600 for a half-day — but give you control over timing and stop duration. The Seychelles tourism board licenses operators, so check that your skipper holds a valid permit before booking.

Best time of year for water clarity

The southeast monsoon — May to October — brings stronger winds and rougher seas, which stir up sediment and reduce visibility around Coco. The northwest monsoon, from November to April, offers calmer conditions and clearer water. December through March is the sweet spot for snorkeling, though you’ll pay higher accommodation rates during the European winter holidays.

One thing the brochures don’t mention: even in calm season, the swell can wrap around the island’s eastern side and create a surge that pushes snorkelers toward the granite boulders. A kids snorkel set with a dry-top snorkel helps younger swimmers avoid swallowing water when the surface gets choppy.

What to pack and how to handle the day

Coco Island has zero infrastructure. No shade, no fresh water, no toilet. Everything you need for the stop comes off the boat with you.

A dry bag is essential — not just for electronics, but for keeping snacks and spare clothes sand-free. The beach is narrow, and the tide comes up quickly. I’ve watched people scramble to rescue towels and bags more than once. A waterproof phone pouch lets you take photos without worrying about salt spray, though honestly, the best shots come from a dedicated action camera with a wrist strap.

Getting the timing right with family

Michael and the kids joined me on a Coco trip last November. What worked: we booked a private charter that left Praslin at 7:30 a.m., hit Coco first, and had the reef to ourselves for a full hour. What didn’t work: I underestimated how quickly Lily and Ethan would get cold in the water, even in November. The water temperature sits around 27°C year-round, but after 30 minutes of floating, the wind chill kicks in. Pack a lightweight reef sun shirt for each person — it buys you another 20 minutes of comfortable snorkeling time.

Local etiquette on the water

Seychellois boat crews take reef protection seriously. You’ll hear the phrase “pa touche” — don’t touch — repeated before every snorkel stop. Standing on coral, collecting shells, and feeding fish are all discouraged, and some operators will call you out publicly if they see it. The fine for damaging protected marine areas can reach SCR 10,000, though enforcement is inconsistent. Better to float and look.

Coco Island — your questions answered

Is Coco Island worth visiting if I don’t snorkel?

Probably not. The island itself is a bare granite outcrop with a narrow sand fringe — there’s nothing to do on land. The entire value of the stop is in the water. If you’re not planning to get in, you’d be better off spending extra time on Curieuse or skipping the boat trip altogether.

That said, the boat ride between islands is scenic, and some visitors enjoy just floating in the shallows with a mask. But honestly, the snorkeling is the draw.

How deep is the water around Coco Island?

The reef starts at about one metre and drops to around five metres at the outer edge. That makes it accessible for beginners and kids who are comfortable putting their face in the water. The shallow depth also means good natural light for photography, especially between 9 a.m. and 11 a.m.

Just be careful not to kick the coral — the reef is fragile, and the shallow water means fins can make contact easily if you’re not paying attention.

Can I visit Coco Island independently without a tour?

Technically yes, but practically no. There’s no public ferry or water taxi service to Coco. You’d need to charter a private boat from Praslin, which costs €400–€600 for a half-day. Most visitors find that a shared group tour at €80–€120 per person makes more sense.

Private charters do offer one advantage: you control the timing and can arrive before the group boats. If your budget allows, it’s the better experience.

What marine life can I expect to see?

Parrotfish, sergeant majors, triggerfish, and butterflyfish are common in the shallows. Turtles appear regularly, usually cruising along the reef edge. On lucky days, you might spot an eagle ray or a blacktip reef shark passing through the channel between Coco and the neighbouring islets.

The coral diversity is good for such a small reef — table corals, brain corals, and branching Acropora are all present. Just remember that visibility depends on swell and recent weather, so what you see varies from week to week.

Is Coco Island suitable for young children?

It depends on the child. The water is shallow and calm in the right conditions, which helps. But there’s no shade, no toilet, and no place to sit comfortably. Kids who tire quickly or get cold easily will struggle after 20–30 minutes.

If you’re travelling with younger children, bring warm gear, snacks, and a plan to get back on the boat when they’ve had enough. A private charter makes this easier — you’re not stuck waiting for a group schedule.

One last thing about Coco

The reef around Coco Island holds up better than many in Seychelles, partly because it’s remote and partly because the granite shelf protects it from the worst of the swell. But that protection works both ways — the same geography that keeps the coral healthy also concentrates boat traffic in a small area. The window between peaceful and crowded is narrow. Catch it right, and you’ll understand why people make the trip. Miss it, and you’ll wonder what the fuss was about. Building a Seychelles itinerary that prioritises timing over distance is the difference between a good day and a great one.
