Casting a Line into the Andes: Your Expert Guide to Fly Fishing Around Cuenca, Ecuador

As a certified local guide who has spent years leading anglers through the Azuay highlands, I can tell you this: fly fishing around Cuenca is not just a sport; it’s a communion with the páramo. While our city's colonial architecture is a UNESCO World Heritage site, the true heritage of this region is written in its wild, crystalline rivers and alpine lakes. For the angler seeking an experience that marries stunning Andean beauty with the thrill of the catch, there is no equal.

But let's set the record straight. This isn't a casual cast in a stocked pond. Success here demands respect for a powerful environment, an understanding of wily, high-altitude trout, and meticulous preparation. From the windswept lagoons of Cajas to the tumbling streams closer to town, each location offers unique rewards and requires specific knowledge. My goal is to give you the insider's edge—the details that make the difference between a frustrating day and an unforgettable adventure.

The Angler's Palette: Rivers and Lakes to Explore

Cuenca is the hub of a network of rivers fed by glacial melt and the sponge-like páramo grasslands. These cold, oxygen-rich waters are home to feisty rainbow trout (Oncorhynchus mykiss) and the more elusive brown trout (Salmo trutta), introduced species that have thrived here.

• Parque Nacional Cajas: This is the undisputed crown jewel. With over 270 lakes, Cajas is a high-altitude angler’s paradise. The primary access point is Laguna Toreadora, sitting at a breathtaking 3,910 meters (12,828 feet). The well-marked Ruta 1 trail, a moderate 2.5-hour loop around the lake, offers dozens of excellent casting spots from the shore. The waters here are gin-clear and cold, and the wind is a constant companion. For a more remote experience, the chain of lakes along the Río Mazán offers solitude, but access requires a guide and a challenging hike.
• Río Tarqui & Río Yanuncay: These are two of the four rivers that frame Cuenca. While sections near the city can be pressured, a short drive upstream reveals excellent pockets and riffles holding stocked rainbows. These are perfect for a half-day trip and are far more forgiving than Cajas in terms of altitude and weather.
• Río Soldados: West of Cuenca, before you reach Cajas, the Soldados area offers a mix of small lakes and a meandering river. It's a local favorite, less crowded than the main Cajas lagoons, and known for holding surprisingly large brown trout that demand a stealthy approach.

Gear Up: Essential Equipment for Andean Angling

Packing correctly is non-negotiable. The Andean weather is notoriously fickle, and the terrain is unforgiving.

• Rod and Reel: Your all-around best choice is a 9-foot, 5-weight fly rod. It has enough backbone to punch through the Cajas wind but is still delicate enough for a subtle presentation. Pair it with a reliable disc-drag reel.
• Line: A weight-forward floating line is your workhorse. However, I always carry a spool with a clear intermediate sinking line for Cajas. When the wind picks up and the trout go deep in the lagoons, it can save your day.
• Waders and Boots: Leave the lightweight gear at home. You need insulated, breathable waders. The water temperature in Cajas rarely breaks 10°C (50°F). Felt-soled boots are fine, but I prefer rubber soles with studs for gripping the often-slippery, moss-covered rocks and boggy páramo terrain.
• Clothing Layers: Think "four seasons in one day." You need moisture-wicking base layers, a fleece mid-layer, and a high-quality, fully waterproof and windproof shell jacket. Do not skimp on the jacket—a "water-resistant" one will fail you in a persistent Andean downpour. Pack a warm beanie, gloves, and a sun-blocking hat.
• Leader and Tippet: Long, 9- to 12-foot leaders tapering to 5X or 6X are essential. The water clarity is exceptional, and the trout are easily spooked.
• Flies: The Local Guide's Box:
  • Dry Flies: Parachute Adams, Elk Hair Caddis, and Griffith's Gnats (sizes 14-20). The hatches can be subtle, often consisting of tiny midges.
  • Nymphs: Beadhead Pheasant Tails, Prince Nymphs, and Hare's Ears (sizes 12-18) are mandatory. Insider Tip: After a rain, when the water clouds slightly, a small, flashy red or pink San Juan Worm can be absolutely deadly.
  • Streamers: Wooly Buggers and Clouser Minnows in olive, black, and brown are crucial for fishing the deeper parts of the lakes, especially for enticing larger brown trout.

Logistics: Getting to the Water

Accessibility ranges from simple to expedition-level.

• Cajas National Park:
  1. By Bus: This is a surprisingly easy and authentic option. Go to the main Terminal Terrestre. Look for the Cooperativa de Transporte Occidental buses heading to Guayaquil. The fare is a fixed $2.50 USD. Tell the driver: "Me deja en La Toreadora, por favor." (Please let me off at Toreadora). The ride is about 45 minutes. Arrange your return time with a driver or plan to flag down a returning bus before 4 PM, as they become less frequent.
  2. Park Entrance Fee: Foreigners pay a $7 USD entrance fee, which you register for at the visitor center. You must present your passport or a copy.
• Río Tarqui & Río Yanuncay: A taxi or rideshare (around $5-$10 from El Centro) is the easiest way to get to the productive upstream sections. Ask to be taken to "San Joaquín" or "Baños" and then direct them further up the river road.

Altitude Acclimatization: Your First Line of Defense

Soroche, or altitude sickness, is a serious risk that can ruin your trip. I've had to assist many unprepared travelers who underestimated it.

1. Acclimatize in Cuenca: Spend at least two full days in Cuenca (2,560 meters / 8,400 feet) before attempting to fish in Cajas.
2. Hydrate Aggressively: Drink double the amount of water you normally would, starting the day before your trip. Coca tea (mate de coca) is a local remedy that genuinely helps. Avoid alcohol completely.
3. Move Deliberately: In Cajas, walk at half your normal pace. There's no prize for getting to the water first. Let your body adjust.
4. Listen to Your Body: A mild headache is common. Severe headaches, nausea, or dizziness are red flags. If they occur, your only cure is to descend immediately.

⚠️ Guide's Safety Briefing: The Dangers Tourists Underestimate

As a guide, my top priority is bringing you back safely. Beyond altitude sickness, two hidden dangers in Cajas catch visitors off guard.

1. The Páramo Ground Itself: The beautiful, green, mossy ground looks solid, but it's often a waterlogged sponge. One wrong step and you can sink to your knee in icy water. A wet foot at 4,000 meters is not just uncomfortable; it's the first step toward hypothermia. Probe questionable ground with your wading staff before committing your weight.

2. Sudden Disorientation: The Andean weather shifts in minutes. A sunny morning can vanish into a thick, disorienting fog or garúa (a cold, heavy drizzle) that reduces visibility to less than 10 meters. Trails disappear, and every direction looks the same. Without a guide or GPS expertise, it is terrifyingly easy to get lost. Never fish alone in remote areas of the park.

Tour Guide's Pre-Trip Checklist

Before your boots hit the trail, run through this mental checklist:

• Acclimatized for 48 hours? If not, stick to the lower rivers today.
• Informed someone of my plan? Leave your itinerary and expected return time with your hotel or a contact.
• Checked the forecast? Look at a mountain-specific forecast, but pack for the worst regardless.
• Got cash for the bus and park fee? Small bills are essential.
• Packed enough water and high-energy food? You'll burn more calories than you think. Local Tip: Pack a couple of humitas (steamed fresh corn cakes) from a local market. They are the perfect, energy-dense trail food.
• Is my phone fully charged and in a waterproof case?

Conclusion: The Reward of Preparedness

The joy of watching a wild Andean trout rise to your fly, surrounded by the dramatic silence of the Cajas highlands, is an experience that stays with you. It’s a reward earned through careful preparation and profound respect for the environment. By heeding this advice, you’re not just planning a fishing trip; you’re preparing for a true Andean adventure.

After a long, cold day on the water, there's no better way to finish than stopping at one of the small restaurants near the park entrance for a steaming bowl of locro de papas (creamy potato and cheese soup) and a hot canelazo to warm your soul. That’s the full Cuenca fishing experience.
