Misty peaks, phantom lights, and alpine lore in the Ecuadorian Andes

High in the southern Ecuadorian Andes, where the continental divide shifts into a labyrinth of jagged glaciated peaks, damp grasslands, and cloud-swirled valleys, lies Parque Nacional Cajas. 

Located roughly 30 kilometres west of the colonial city of Cuenca, this protected expanse sits at altitudes ranging between 3,100 and 4,450 metres above sea level. It is a realm defined by its stark, wind-swept páramo ecosystem—a high-altitude tundra found exclusively in the northern Andes—and an astonishing network of more than 200 glacial lagunas.

For long-distance cyclists tackling the dramatic climbs of the Azuay province, independent trekkers navigating alpine passes, and curious road-trippers navigating the twisting highway towards the Pacific coast, Cajas offers an immersive wilderness experience. 

Yet alongside its botanical significance and dramatic geology, Parque Nacional Cajas holds a distinct reputation: it is widely regarded as Ecuador’s primary hotspot for unidentified aerial phenomena (UFOs) and high-altitude sky-watching.

Why is Parque Nacional Cajas associated with UFOs?

Parque Nacional Cajas attracts UFO reports due to its extreme altitude above 4,000 metres, minimal light pollution, and unusual atmospheric conditions created by dense fog reflecting off hundreds of glacial lagunas. These physical factors intersect with centuries-old Andean oral traditions regarding celestial spirits and modern contactee accounts.

High-altitude essentials / Cajas at a glance

Whether you are grinding up the continental divide on two wheels or hunting for phantom lights by the lagunas, Cajas is an alpine wilderness like no other. Here is your quick-reference guide to southern Ecuador’s most mysterious high-altitude national park.

• The Setting: Parque Nacional Cajas lies just 30 kilometres west of Cuenca, covering over 28,000 hectares of high-altitude páramo tundra and more than 200 glacial lakes between 3,100 and 4,450 metres elevation
• The UFO Connection: Extreme altitude, zero light pollution, and sudden atmospheric garúa fog reflecting off glacial waters make Cajas Ecuador’s premier location for high-altitude sky-watching and light phenomena
• Local Folklore: Ancient Cañari and Inca sacred spaces (huacas) intersect with modern contactee accounts and the legend of the Guagua Grande—a tall humanoid entity said to inhabit the ravines
• The Epic Climb: The Tres Cruces Pass on the E582 highway tests long-distance cyclists with a 2,500-metre elevation gain over 35 kilometres, topping out at the continental divide at 4,160 metres
• Ancient Trails: The Laguna La Toreadora circuit links day-hikers and bikepackers to rare, high-elevation Polylepis paper-tree forests and preserved stone sections of the Qhapaq Ñan Inca highway
• Unforgiving Elements: Sub-zero night temperatures, waterlogged spongy terrain, and rapid cloud cover mean proper multi-layer waterproofs, thermal gear, and GPS navigation are mandatory
• Conservation Rules: Open fires are strictly banned across this protected RAMSAR wetland; campers must register at ranger stations and rely on multi-fuel camp stoves

4,000 metres up in Ecuador’s cloudiest playground

Navigating through Parque Nacional Cajas often feels less like an alpine hike and more like wandering through a giant, wet cloudscape. Thick banks of fog—known locally as garúa—roll over the exposed ridges without warning, swallowing mountain peaks whole and turning the spongy tundra into a quiet, monochromatic landscape.

The weather here changes its mind faster than a cyclist on a steep incline. Warm, moist air rising from the Pacific basin collides head-on with frigid mountain currents coming off the high Andes. The result? Rapid condensation, sudden rain squalls, shivering temperatures, and bizarre optical tricks where sunlight hits mist and glacial water all at once.

Thin air, dark skies, and ancient stargazers

This high-altitude environment sets the perfect stage for Cajas’ status as Ecuador’s go-to destination for sky-watching. When the cloud cover splits open at night, the total absence of urban light pollution leaves you staring into a ridiculously crisp cosmic display. At 4,000 metres, the atmosphere is thin enough to make satellites, shooting stars, and unexplained high-altitude flickers look exceptionally bright and close.

Celestial observation in Cajas isn’t just a modern trend for people with telescopes, though. Long before Spanish colonisation, the local Cañari and Inca civilisations viewed these high-altitude lagunas as sacred huacas—meeting grounds where the earth talked directly to the night sky. Unexplained lights, halos around the moon, and strange atmospheric reflections were woven straight into Andean cosmology. 

Modern UFO stories in Cajas are really just the latest chapter in a very old tradition of staring up at the Andean sky and wondering what on earth (or off it) is going on.

Glowing orbs and phantom lights over Laguna La Toreadora

The modern wave of Cajas alien stories took off in the late 20th century, fed by a steady stream of weird tales from overnight campers, park rangers, and local night-skiers. The classic report usually goes like this: someone is freezing in their tent near Laguna La Toreadora or Laguna Llaviuco, looks up, and spots a silent, luminous sphere zip across the sky before diving straight into the ice-cold water without making a splash.

These aren’t your standard commercial flight patterns. Observers consistently report self-luminous orbs—glowing in brilliant shades of amber, electric blue, or stark white—that pull off impossible right-angled turns and sudden stops before disappearing behind mountain crags. The total silence of these displays, paired with the eerie quiet of the páramo, is enough to make even the most sceptical trekker double-check their tent zip.

Ufologists, campfire yarns, and Jaime Rodríguez

No discussion of Cajas lore is complete without mentioning Jaime Rodríguez, Ecuador’s most prominent ufologist. Rodríguez spent decades cataloguing sightings across the Azuay region, gathering accounts from mountain guides, locals, and baffled tourists. 

His archives are full of classic contactee tropes: campers sitting around multi-fuel stoves near the high passes who suddenly watch their headlamps flicker out, camera batteries drain to zero in seconds, and wristwatches stop working just as strange light formations float over the ridgeline.

Whether these encounters are extra-terrestrial visitors taking a scenic detour, military test craft, or simply pockets of swamp gas (will-o’-the-wisp) reacting with high-altitude methane and freezing mist depends entirely on how much mystery you like with your hot chocolate.

Guagua Grande / Cryptids, big babies, and alpine monsters

If glowing space ships weren’t enough, Cajas has its own local cryptid to keep campers on their toes. Enter the Guagua Grande—which translates roughly from regional Kichwa-influenced Spanish as the Big Baby.

According to local folklore, the Guagua Grande is a strange, tall humanoid figure that haunts the remote ravines and twisted Polylepis (paper-tree) forests deep inside the park. 

Depending on who is telling the story around the hostel common room, the entity is described either as a slender, pale figure with an oversized head and massive eyes, or as an ancient, slightly mischievous mountain spirit protecting the high lagunas from disrespectful humans.

Over the years, the line between traditional Andean mountain spirits and modern Grey alien archetypes has blurred completely. Local guides will happily tell you about light spheres and the Guagua Grande in the very same breath, proving that wet mountain air and high-altitude solitude are great for keeping folklore alive and kicking.

Gravel, grunt, and glaciers / Tackle the routes

If you want to explore the park and hunt for phantom lights yourself, you will need a solid plan. The physical routes through Cajas are spectacular, demanding, and very real.

The Tres Cruces Pass / Gravel & road cycling

Sitting on the main E582 road connecting Cuenca to Guayaquil, Tres Cruces is the highest road pass in the park at roughly 4,160 metres. It marks the continental divide—water on one side heads to the Amazon, water on the other flows to the Pacific. Cyclists face a brutal 2,500-metre elevation gain over 35 kilometres from Cuenca. It is windy, exposed, cold, and offers sweeping 360-degree views of the tundra, making it a prime spot for evening sky-watching if the fog clears.

Laguna La Toreadora Circuit / Day trekking

Starting near the main ranger station, this well-marked loop skirts the shores of Laguna La Toreadora and links up with remnants of the ancient Inca highway (Qhapaq Ñan). You will pass through eerie Polylepis forests—among the highest-elevation woodlands on Earth—and get front-row access to the lagunas where many orb sightings are reported.

Camino de Inga Trail / Multi-day bikepacking & trekking

A rugged south-to-north traverse taking you deep into the park’s interior past isolated lakes like Laguna Suerococha. This is proper back-country territory: no phone signal, no facilities, and complete isolation under the Andean night sky.

Cold feet and high altitude / How not to get stranded

Before you pack your camera and set off to hunt for alien light spheres, remember that Cajas takes no prisoners when it comes to extreme weather. Respecting the environment is key to staying safe.

Respect the altitude (soroche)

Altitude sickness is no joke. Spend at least two or three days acclimatising in Cuenca (2,560 metres) before attempting heavy climbs or sleeping out above 3,900 metres.

Gear up for sub-zero drops

As soon as the sun goes down, temperatures plummet towards freezing (0°C to 4°C is standard, and lower in winter). You need a proper multi-layer system, windproof/waterproof outer layers, a high-R-value sleeping mat, and a solid three-season sleeping bag. Waterproof boots are essential unless you enjoy hiking in soaked socks across spongy ground.

Navigation essentials

Thick garúa fog can wipe out visibility in under two minutes, leaving you completely disoriented. Always carry an offline GPS map, a physical topo map, and a compass.

Park rules & conservation

Cajas is a protected RAMSAR wetland that supplies Cuenca’s municipal drinking water.

• Registration: Check in at the Toreadora or Quimsacocha visitor stations on arrival.
• Designated Camping: Camp only in approved spots to protect fragile páramo vegetation.
• No Open Fires: Campfires are strictly banned. Bring a reliable camp stove.
• Leave No Trace: Pack out every scrap of rubbish and stay on established tracks to prevent severe soil erosion.

Whether you come for the tough gravel climbs, the haunting high-altitude scenery, or the chance to spot an amber sphere hovering silently over a freezing glacial lake, Parque Nacional Cajas delivers one of the weirdest and most unforgettable adventures in the Andes.

Keep your eye on the ridge and your hands on the brakes

Climbing into Cajas from the cobblestones of Cuenca is a rite of passage for any self-respecting touring cyclist or independent trekker. As the urban noise fades into the heavy hush of the high páramo, the sheer scale of the landscape takes over. Thin air burns the lungs, and cold rain will test your waterproofs, but the rewards—glassy glacial lakes, ancient paper-tree groves, and sprawling views across the continental divide—are worth every ragged breath on the pedals.

Whether you spend your evening scanning the cold night sky for glowing amber spheres or simply huddled over a gas stove nursing a warm brew, Cajas leaves an indelible mark. The distinction between high-altitude atmospheric refractions and mountain mythology matters far less than the feeling of standing under an unblemished canopy of stars at 4,000 metres. It remains a rare corner of the Andes where dramatic wilderness and eccentric local folklore sit side by side comfortably.

Prepare thoroughly, respect the fragile tundra, and give yourself plenty of time in Cuenca to acclimatise before pushing up into the clouds. The local public buses running from Cuenca’s Terminal Terrestre offer an easy safety net if your legs give out, but tackling the high passes under your own power provides a perspective on the southern Ecuadorian Andes that no tour bus can match.

Pack your thermal base layers, keep your offline maps loaded, and keep an open mind. If an unexplained light happens to streak silently across Laguna La Toreadora while you are zipped into your bivvy, consider it an added bonus to one of South America’s finest wild rides.
