Great Andes Trail: Argentina’s Landmark Decree for Sustainable High-Mountain Tourism in Mendoza

As the first long-distance high-mountain trail of its kind in Argentina, the Great Andes Trail is distinguished by its unprecedented scale. The connection between Aconcagua and the Pehuenche Pass is facilitated through a network of sports, tourism, and cultural sections. Within this corridor, six protected natural areas are crossed, further reinforcing the environmental profile of the province. These protected zones include the Aconcagua Provincial Park, the Cordón del Plata Provincial Park, and the Tupungato Provincial Park. By threading these areas together, a cohesive narrative of conservation is maintained across some of the most dramatic landscapes in South America.

The ecological integrity of the trail is bolstered by the inclusion of several critical natural reserves. The Manzano-Portillo de Piuquenes Natural Reserve, the Laguna del Diamante Natural Reserve, and the Laguna del Atuel Natural Water Reserve are all integrated into the route’s geography. Together, these territories are estimated to cover approximately 30% of Mendoza’s total provincial surface. Because these high-mountain environments are characterized by their fragility, the formalization of the trail is seen as a vital step in safeguarding water sources and high-altitude flora and fauna. These spaces are no longer viewed as isolated pockets of wilderness but are instead treated as a unified ecological corridor.

While many segments of the trail are defined by the difficult access and physical demands typical of the high Andes, a spectrum of difficulty levels is considered within the project. Less complex routes are included to ensure that the experience is not limited to elite mountaineers. Accessible sectors, such as the Mountain Park located near the City of Mendoza, are utilized to expand citizen participation and local engagement. This tiered approach allows for a broader demographic of visitors to interact with the mountain environment, thereby fostering a deeper public connection to the provincial landscape and its preservation.

The fundamental philosophy of the Great Andes Trail is rooted in ecotourism, which is leveraged as a primary tool for sustainable development. Low-impact activities, such as trekking and hiking, are promoted to encourage direct contact with the natural world without the degradation often associated with mass tourism. Through this modality, environmental education is facilitated, as travellers are made aware of the delicate balance required to maintain high-mountain ecosystems. The knowledge of cultural heritage is also deepened, strengthening the collective consciousness regarding the necessity of conservation.

Beyond environmental benefits, the local economy is expected to be significantly boosted by the formalization of this route. Opportunities are created for family-owned businesses, specialized mountain guides, and various service providers related to outdoor activities. By channelling tourism into rural and high-altitude areas, a decentralized economic model is supported. This ensures that the benefits of the trail are felt by the communities that have historically resided in the shadows of these peaks. Consequently, a proposal that harmonizes conservation, identity, and responsible growth is consolidated in the heart of the Andes.
