Located in la Garrotxa, ATMA is a company created to study, manage and promote tourism and the tourist resources in the environment.
The Agència de Turisme Medi Ambiental (Environmental Tourist Agency) offers a comprehensive service of tourist resources in the Garrotxa district. Located in the Zona Volcánica de la Garrotxa Natural Park, it occupies a building on the Avinguda de l'Estació, which is the start of the Carrilet d’Olot greenway. Now the former line of this track is the central section of the greenways of Girona, which connect the Pyrenees with the Mediterranean.
The ATMA centre houses the Centre Logístic de Bicicletes (Bicycle Logistics Centre), which offers material rental and 16 routes around the most emblematic areas of the zone, as well as three greenways that cross the region, suitable for both cyclists and walkers. They also provide visitors with specialised guides for pedagogical, cultural or scenic excursions.
