Alphonse Island sits at the southern edge of the Seychelles outer islands, roughly 400km southwest of Mahé. It's not an easy place to get to. But serious saltwater fly anglers don't choose Alphonse because it's convenient — they choose it because very few places on earth fish like it does.

I spent 18 months guiding here. This is what I know.

The fishery

Alphonse is defined by its variety. The atoll hosts what I believe is one of the finest bonefish fisheries in the world, but that's almost underselling it — because on the right day, you can realistically get shots at five different species. Bonefish, permit, giant trevally, triggerfish, and milkfish. The Seychelles Big 5. In a single day on the water.

That's not a marketing claim. I've seen it happen. Multiple times.

The flats at Alphonse stretch across roughly 40km of wadeable terrain. Huge shoals of bonefish move across the sand flats in the early morning light, while large singles cruise the edges — nervous, fast, and deeply rewarding when you get it right. The bonefish here run big. Don't be surprised when what looks like a small school turns out to be a group of fish pushing 4kg.

Giant trevally

GT on Alphonse is not the relentless numbers game you'll find on Cosmoledo. The flats here produce consistent opportunities rather than prolific numbers, and the fish tend to be quality. When the tide is right — particularly the pushing tide in the late afternoon — GT move onto the flats looking for an easy meal, and they eat with conviction.

Fish them on a 10 weight. Strip fast. Don't stop.

Permit

Alphonse carries a healthy permit population and genuine shots at them on most days, particularly on the tailing flats in the early morning. They're educated and they're picky. A Flexo Crab in size 4 or 6, presented accurately and stripped slowly, is your best option. Be prepared to be refused. That's permit fishing.

Triggerfish

This is where Alphonse genuinely stands out. The triggerfish population on Alphonse is one of the most abundant and healthy I've encountered anywhere in the Seychelles. On the right tides, you'll see dozens of fish in a single session — heads down, tailing aggressively, eating off the bottom. Technical fishing that demands accuracy and patience. Deeply, deeply satisfying when you crack it.

Milkfish

Milkfish on fly is the holy grail of saltwater fishing. Rare everywhere. But Alphonse is one of the handful of places in the world where targeting milkfish is a legitimate daily option. In the early morning, before the sun gets too high, you'll find them feeding in the deep water just outside the atoll. A well-presented fly in the feeding lane is your only shot. When it works, there is nothing else like it.

Season

Alphonse fishes from September through May. Peak season runs October through April, when conditions are most stable and the fishing most consistent. The shoulder months — September and May — still produce excellent fishing with slightly more variable wind and weather.

The lodge closes from June through August during the northwest monsoon season. Don't try to go. The fishing isn't worth it and the conditions can be brutal.

Getting there

Fly to Mahé, the main island of Seychelles. From Mahé, you'll take a light aircraft to Alphonse — roughly 45 minutes. Transfers are organised through the lodge and typically aligned with your fishing week schedule. Plan for two international connection points depending on where you're flying from — Alphonse is genuinely remote, and that's entirely the point.

The lodge

Alphonse Island Resort is the only accommodation on the island. It's genuinely world-class — exceptional food, beautiful rooms, warm staff, and everything you'd need for a trip of this value. It's not a rough camp. Non-fishing partners are well catered for with snorkelling, diving, and an island that's worth exploring in its own right.

For a trip that's as much about the experience as the fishing, Alphonse delivers on both fronts.

What to bring

Bring three rods. An 8 weight for bonefish and triggerfish. A 10 weight for permit and GT. A 12 weight if milkfish is on your list — and it should be.

Tropical floating lines only. Temperate lines go limp in the Seychelles heat and will cost you distance and accuracy at the worst possible moment.

Large arbour reels with plenty of backing on everything. Bonefish on Alphonse run hard and they don't stop.

Leaders: 12–16lb fluorocarbon for bonefish and triggerfish. Heavier for GT and milkfish.

Sun protection is non-negotiable. Full coverage shirt, buff, wide brim hat, reef-safe SPF 50. The reflection off the flats doubles your UV exposure. Take it seriously.

The flies you need

Three patterns cover most situations:

Gotcha — size 6, pink or tan. The bonefish fly. Fast retrieve on the flats.

Flexo Crab — size 4–6. Permit and triggerfish. Fish it slow. Let it sink.

Brush fly or Gurgler — size 2/0. GT on the surface. Strip fast and don't stop.

Bring more than you think you need. Losing flies to coral and fish is inevitable.

Who Alphonse is for

Alphonse is the most accessible of the Seychelles outer islands — suitable for anglers from their first saltwater trip through to experienced hands looking for variety and world-class conditions. If you're travelling with a non-fishing partner or family, Alphonse is the one to choose.

If you're looking purely for the most demanding, remote, hardcore experience — consider Astove or Cosmoledo. But if you want the complete Seychelles fly fishing experience on one extraordinary island, Alphonse is the answer.
