Parques Nacionales is a must-have app for anyone planning to visit the Spanish National Parks. Developed by Centro Nacional de Información Geográfica - CNIG, it is available for free on Android. The app is a comprehensive guide to the history, fauna, flora, and excursions in the National Parks.

The app boasts a database of hundreds of points of interest including information centers, accommodations, viewpoints, and shelters, with their respective locations and contact information. It also provides information on routes to explore with details on duration, difficulty, and more. All this is presented on the cartography of the Instituto Geográfico Nacional.

One unique feature of the app is the ability to download data for the National Park of your choice, making it possible to use the app without an internet connection. The app is easy to use, and the interface is intuitive, making it accessible to all.
