Fly fishing in Chilean Patagonia: a travel guide

The Coyhaique region of Chilean Patagonia is some of the best dry fly water in the world. Resident brown and rainbow trout eat off the surface through the summer. The season runs from mid-October to early May. You can fish it from a lodge, from a private cabin, or on your own.

This article is an overview of everything we have written about fly fishing in Chilean Patagonia. Most sections link to a full article.

When to go

Any time in the season works, because the fish are mostly resident and eat all summer. What changes is how you fish.

• November: high, cold water, streamers and nymphs, few people.
• December: the rivers drop and the dry fly starts.
• January: caddis and mayfly hatches.
• February: hatches, then beetles and hoppers.
• March: terrestrials and the big fish on top.
• April: streamers and the last of the dries.

Month by month: best time to fish Patagonia. Patagonia’s season is the northern winter, so it pairs with a summer in the Arctic: where to fish, month by month.

Getting to Coyhaique

Fly to Santiago, then take the domestic flight to Balmaceda, a couple of hours on LATAM or Sky. From the US a return to Santiago is usually $700 to $1,200 in January to March, from Europe €1,200 to €1,500. Santiago to Balmaceda is usually €100 to €250 return. You collect your bags in Santiago, clear customs and check in again, so leave plenty of time between the flights.

What it costs, and lodge, self-guided or DIY

Per person for a week, before flights and tips:

• A lodge week: $6,500 to $8,000. A guide every day, all meals, transfers. Every decision is made for you.
• DIY with two guided days: about $1,200 to $1,500 for a car, a hostal and the guide days. The planning is on you.
• A private cabin with guided days: our River Week from €1,800, or the Guided Week with a guide every day from €3,900.

Fishing on your own

DIY fly fishing is doable in Chile. We’d still recommend a few guided days, to get you started and to fish the lakes. The lakes are difficult without a boat, so a guide is pretty much required for them.

• Access: you can reach the rivers from the bridges and a few other points where the road runs right next to the river.
• Licence: buy it online from Sernapesca before you go. On our trips it is included.
• Spanish: it helps a lot.

Flies and gear

Mid-December to mid-March is the peak dry fly period: caddis and mayfly hatches first, then beetles and hoppers. Streamers and nymphs work all season. What hatches when, and the patterns to match it: flies for Patagonia.

A 9 foot 5 weight for the dries and a 6 weight for streamers and wind. The full list: what to pack for fly fishing in Patagonia.

The weather

The weather in Patagonia is known for its sudden changes throughout the day, so even in midsummer be prepared for sunshine, rain and wind. Dress in layers and keep the rain jacket with you. The sun’s UV is stronger than it feels, so bring sunscreen, a hat and a buff.

Renting a car

• Get a car with proper tyres for gravel roads, and a spare in the back if possible.
• Take photos of every dent before you drive off.
• In February 2026 there were major roadworks on the Carretera Austral between Villa Cerro Castillo and Puerto Río Tranquilo, and it was mostly gravel. Paving is likely still going on, so expect delays.

Car prices are in the cost article.

Days off the water

• The Cerro Castillo day hike. A climb to a glacial lagoon under the hanging glacier and the towers. Start early and bring layers.
• Kayaking the Marble Caves from Puerto Río Tranquilo. Well worth it, even though it gets busy. Go in the morning, before the wind.
