El Cajas National Park

Listen first. Wind moves across the grass with a dry, steady hiss. Somewhere below, water runs over stone. The air is thin and cold, and it carries the smell of wet earth and crushed leaves. Fog may drift across the road while you watch, hiding a lake one moment and showing it the next. You are standing high in the Andes of southern Ecuador, in a landscape that looks almost nothing like the colonial streets of Cuenca you left behind.

El Cajas National Park lies west of Cuenca, in the province of Azuay. The drive from the city takes less than an hour, but the change is dramatic. Red-tiled roofs and church domes give way to farmland, then to eucalyptus, then to open, treeless highland. The park covers a wide area of mountain terrain. Its elevations climb from roughly three thousand metres to well above four thousand. Many visitors feel that height in their lungs within minutes of stepping outside.

The ecosystem around you has a special name: páramo. Páramo is a high-altitude grassland found in the northern Andes, above the forest line and below the permanent snow. At first glance it can look empty. Look closer, and the ground turns out to be crowded. Tough tussock grass, small flowering plants, mosses, and dense cushion plants cover almost every surface. Many of these plants grow very slowly. A single footprint in the wrong place can damage growth that took years to form.

Here is the first thing many visitors miss. This spongy ground is one of the most important water systems in the region. The páramo soil and its plants hold rain and mist like a sponge, then release the water slowly into streams. Rivers that begin in these hills flow down toward Cuenca. A large part of the city's drinking water starts its journey here. When you look at a lake in the Cajas, you are also looking at the water supply of a city.

And there are a great many lakes. The park holds hundreds of lagoons, scattered across valleys carved by ancient glaciers. Some are large and dark, others are small pools that catch the sky like mirrors. Because of this dense network of wetlands, the park is listed under the Ramsar Convention, an international agreement that protects wetlands of global importance. On a clear day, a short walk can bring several lakes into view at once, each one a slightly different shade of grey, blue, or green.

Where does the name come from? Nobody seems entirely sure, and you will hear more than one explanation. One popular idea links it to the Spanish word caja, meaning box, because many lakes sit in deep, box-like basins. Another suggestion points to an older Indigenous word connected with cold. Both stories are told locally. Treat them as possibilities rather than settled fact, and decide for yourself which one fits the landscape in front of you.

Now, a second surprise. Among the open grassland, in sheltered gullies and on rocky slopes, you may find small, twisted forests. These are Polylepis trees, known locally as paper trees. Their red-brown bark peels away in thin, papery layers, sheet after sheet. Polylepis grows higher than almost any other tree in the world. Walking into one of these groves feels like entering a different place: darker, quieter, damp, with moss hanging from crooked branches and the wind suddenly gone.

People crossed these mountains long before the park existed. Remains of the Inca road system, known in Quechua as Qhapaq Ñan, pass through parts of this region. The Inca built this network of roads to link their empire across the Andes. Older cultures, including the Cañari people of southern Ecuador, also knew these highlands well. Today a modern highway runs through the park toward the Pacific coast, following a route between the mountains and the lowlands that travellers have used for a very long time.

Many visitors start near Laguna Toreadora, close to the main road, where there is a visitor area and well-marked trails. A loop around the lake gives you a good first taste of the páramo without a long commitment. On the eastern, lower side of the park, Laguna Llaviucu sits in a greener valley, with more forest and more birdsong. Longer routes lead deeper into the backcountry, but they call for good navigation, proper equipment, and respect for fast-changing weather.

That weather deserves serious attention. In the Cajas, a bright morning can turn into cold rain, hail, or thick fog within an hour. Temperatures near the lakes can drop close to freezing, even when Cuenca feels mild. Trails can become muddy and hard to follow when clouds close in. Bring warm layers, a waterproof jacket, and sturdy shoes. Walk slowly at first, drink water, and give your body time to adjust to the altitude.

If you keep still and quiet, the park starts to show its residents. Hummingbirds work the small flowers, flashing green and violet. One of them, the violet-throated metaltail, lives in only a small area of southern Ecuador, and this park is one of the best places to look for it. Waterbirds rest on the lakes. Hawks ride the wind above the ridges. With great luck, you might see an Andean condor, but sightings are rare, so treat any condor as a gift rather than an expectation.

The light here changes everything. When clouds lift, the lakes turn sharp and reflective, and the far ridges stand out in layers of blue. When fog returns, colour drains away and the world shrinks to a few metres of grass and stone. Both moods are honest portraits of the place. Many photographers find that the misty hours, not the sunny ones, give the Cajas its most memorable character: soft, silent, and a little mysterious.

Before you leave, stop for a moment. Look down at the ground near your feet, at the tight cushions of plants and the beads of water caught in the grass. Then look out at the nearest lake and follow the slope of the land with your eyes. Somewhere down there, that water is already moving toward Cuenca. As you walk back to the road, listen again for the wind, and for the quiet sound of water leaving the mountains.
