Pindus National Park, also known as Valia Calda, is a national park in mainland Greece, situated in an isolated mountainous area at the periphery of West Macedonia and Epirus, in the northeastern part of the Pindus mountain range. It was established in 1966 and covers an area of 6,927 hectares. The park's core zone, 3,360 hectares, covers the greatest part of the Valia Calda valley and the slopes of the surrounding peaks.

Greece is characterized by an extremely fragmented, rugged landscape hosting a great diversity of ecosystems and an outstanding biodiversity. Almost 5% of its extensive coastline consists of ecologically sensitive wetlands. Two thirds of the total population live no further than 2 km from the coast and most of the important urban centers are coastal, while almost all of the tourist infrastructure is divided among islands and the coastal mainland.
