Patagonia, Chile Strengthens Sustainable Tourism Rules for Protected-Area Lodging

The issue of sustainable infrastructure is gaining momentum in Patagonia and the southern protected regions of Chile, as the country revisits its system of concessions, provision of services, and environmental management at its most distant destinations. According to the briefing of September 20, 2026, provided in support of this report, the Undersecretariat of Tourism of Chile has adopted a policy stipulating the use of solar storage systems, the absence of diesel generators, and zero-discharge greywater treatment systems in backcountry tourism concessions functioning at the northern Patagonian trailheads, where compliance with those requirements is conditioned upon the renewal of the concessions since 2027. However, the particular requirement of September 20, 2026, cannot be verified independently using the recent releases of the Undersecretariat of Tourism of Chile or CONAF.

Chile’s Tourism Concessions Already Carry Sustainability Requirements

Chile’s tourism concession system for protected areas operates under Law 20.423 and related regulations.

The Undersecretariat of Tourism states that concessions in state-protected wild areas must be compatible with the conservation objectives of those territories. The process is designed to support tourism products and services that meet quality and sustainability standards while preserving biodiversity and environmental heritage.

The current system involves the Undersecretariat of Tourism, the Ministry of National Assets, the Ministry of Environment and CONAF in preparing technical bases and managing the development of tourism concessions.

This framework is particularly relevant in Patagonia, where accommodation, camps, trails and visitor facilities are frequently located close to sensitive ecosystems.

Patagonia National Park Shows the Scale of the Destination

One of the region’s major protected destinations is Patagonia National Park in Aysén.

CONAF lists the park at more than 304,527 hectares, covering areas in the General Carrera and Capitán Prat provinces. The park contains forests, Patagonian steppe, wetlands and habitats supporting species including huemul, puma, guanaco and Andean condor.

The park is approximately 315 kilometres south of Coyhaique by the Carretera Austral. Access to different sectors varies considerably, with the Chacabuco Valley, Tamango and Jeinimeni areas requiring different approaches.

For international visitors, this remoteness is part of the travel experience but also creates practical challenges for energy, water, waste and sanitation infrastructure.

Solar Energy and Off-Grid Tourism

The reported 2027 requirement for off-grid solar-storage systems could not be verified as a new nationwide or Patagonia-specific legal mandate.

Solar technology is nevertheless already part of Chile’s wider sustainability and energy-efficiency landscape. Current government programmes support photovoltaic and solar thermal installations in several regions, while tourism policy increasingly incorporates sustainability into protected-area development.

Chile’s tourism authorities also operate a national sustainability framework through the Mesa Nacional de Sustentabilidad Turística, which brings together tourism, environmental and public-sector institutions to promote sustainable tourism practices.

For remote lodges, renewable energy can be particularly relevant because conventional grid infrastructure is limited across large parts of Patagonia.

Greywater Treatment Already Has a Tourism Connection

Chile also has an established programme supporting sustainable sanitation systems for tourism businesses in rural and protected areas.

The Undersecretariat of Tourism says its Sistemas Sanitarios Sustentables programme supports small tourism enterprises in rural areas with drinking-water and sanitation solutions, including rainwater collection, greywater reuse and wetland-based systems.

The initiative was developed with the Subsecretariat of Public Health and other public institutions and was originally supported through a public-interest project that examined alternative sanitation technologies for tourism services in rural areas and protected landscapes.

This existing framework provides relevant context for the briefing’s reference to greywater treatment, although the specific 2026 concession-renewal condition remains unverified.

Tourism Infrastructure Faces Practical Constraints

Remote Patagonia requires travellers and operators to plan around changing environmental conditions.

CONAF’s current information for Patagonia National Park notes that snow affects several trails and that camping areas in parts of the Chacabuco Valley remain closed at present. The agency advises visitors to confirm trail conditions with park rangers before beginning excursions.

The park also prohibits dumping waste or contaminating waterways. Visitors must carry generated waste out of the park or place it in designated closed containers, while leaving marked trails is prohibited.

Noise restrictions also apply, and drones are prohibited unless authorised for research or professional filming.

These rules are directly relevant to accommodation operators because visitor infrastructure operates within landscapes where waste, water and energy management are closely connected with conservation.

Patagonia’s Low-Impact Tourism Network Expands

Chile is also promoting responsible travel across the wider Route of Parks of Patagonia.

CONAF introduced a visitor passport in 2026 designed to record visits to participating national parks and protected areas while encouraging responsible travel and a low-impact approach to the region’s natural and cultural heritage.

The initiative connects multiple protected landscapes rather than focusing on a single destination, creating a broader tourism network across southern Chile.

For travellers, this means Patagonia’s tourism experience increasingly combines hiking, wildlife viewing, scenic road journeys and rural accommodation with visitor rules designed around conservation.

What Travellers Should Know

People intending to visit Patagonia should inquire about the current openings of the park, the condition of the trails, accommodation facilities, and transport means before going there. One can go to Patagonia National Park using the road network in Aysén, with Coyhaique being one of the key entry points in the region. People moving further south towards Torres del Paine go into another tourism area in Magallanes, and in that case, different management and access systems come into effect. Therefore, according to the most recent government information, there is an existing sustainability model and not necessarily everything that was mentioned in the report about September 20’s mandate.
