Vallecitos lies in the Cordón del Plata, a high range of the Andes west of Mendoza, and it is known as a small winter ski area and a summer trekking base. The valley sits at an altitude of roughly three thousand metres, with open slopes, rocky ridges and wide views toward some of the highest peaks of the range. A day trek here follows trails across the high valley with a guide, passing streams and meadows, with the thin, clear air and big skies that make Andean hiking so memorable. Trails vary in length and difficulty, and the day tours we link are designed for people with reasonable fitness rather than mountaineering experience. The experience is a full-day trek in the Andes from Mendoza, with transport from the city, and it gives a flavour of the mountains that the Aconcagua day trip, which is mostly viewpoints and short walks, does not. It is a quieter alternative to the busier high-mountain road, and it is popular with hikers who want a proper day on foot.
What you will do
A typical day involves a morning drive from Mendoza into the foothills and up the winding road to the valley, followed by several hours of guided walking at altitude. The pace is steady rather than fast, with stops to rest, take photos and catch your breath.
The scenery changes with the season
In summer the slopes are brown and gold with streams running, and in winter the valley is covered in snow and part of it becomes a small ski area. Guides explain the geology and the natural history, and they carry the safety gear and a first-aid kit.
Planning
Altitude is the main challenge. At around three thousand metres, even short climbs can feel hard if you are not acclimatised, so go slowly, drink plenty of water and tell your guide if you feel unwell. Fitness requirements vary by tour, so choose a day that matches your ability and ask about the distance and elevation gain. The road to the valley can be affected by snow in winter, and operators may change the route or switch to snow activities. Check conditions when you book and be ready for flexible plans.
Practical tips
Dress in layers, because mornings are cold and afternoons can be warm, with a windproof jacket, a hat, sunglasses and strong sun protection. Wear sturdy boots, bring a packed lunch if it is not included and carry at least a litre or two of water. Prices vary with group size and whether lunch and gear are included, and private treks cost more than shared ones.
The trek suits active travellers, families with fit teenagers and anyone who wants a day of exercise between wine tastings. For something gentler, consider the Aconcagua viewpoints, and for something harder, ask operators about longer treks into the Cordón del Plata.
Who it suits
The trek is made for people who want to stretch their legs after days of tasting and sitting in vehicles. It gives a real sense of the scale of the mountains, and the quiet of the valley is a welcome contrast to busier sights. Keep expectations realistic about pace at altitude, and treat the day as a steady walk with plenty of pauses rather than a race.

Good questions
How hard is the trek?+
It depends on the route, but day treks are designed for people with reasonable fitness. Altitude makes even moderate climbs feel harder, so go slowly.
Do I need hiking experience?+
No mountaineering experience is needed for a day trek, but you should be comfortable walking for several hours and bring proper boots.
What should I bring?+
Layers, a windproof jacket, sturdy boots, sunscreen, sunglasses, a hat, water and snacks. Check whether lunch is included.
Is it possible in winter?+
The valley is a small ski area in winter, so trekking may be replaced by snow activities. Ask the operator what is running when you travel.
How is it different from the Aconcagua day trip?+
The Aconcagua day is mostly viewpoints and short walks along the road, while Vallecitos is a full day of walking in the mountains.
