In the El Chaltén area (Los Glaciares National Park) there are two main types of licensed providers: Guides (working individually or organized into associations), professionals licensed by the National Parks Administration who accompany visitors on trails and mountain activities, providing information, safety and local knowledge; and Tourism service providers (companies or operators, which can be sole proprietorships), who organize, sell and market excursions, treks and packages, handling permits, logistics and, in many cases, hiring guides.
