The park contains the Caroux-Espinouse massif, which is the only location in France where Corsican mouflons (wild sheep) were successfully introduced in the 1950s.
It sits on a significant geological fault line, resulting in an unusual mix of ancient Variscan crystalline rocks and limestone causses.
The park features the Sidobre region, a granite plateau known for its massive, precariously balanced boulders formed by erosion.
The Canal du Midi, a UNESCO World Heritage site, borders the southern edge of the park.
The Gorges d'Héric are carved into the Caroux massif, featuring natural swimming pools and polished granite canyons.
The park encompasses the Montagne Noire, a segment of the Massif Central that forms the drainage divide between the Atlantic and Mediterranean watersheds.
The Parc naturel régional du Haut-Languedoc is a protected landscape spanning the transition between the Mediterranean climate and the Atlantic oceanic influence. It encompasses parts of the Tarn and Hérault departments, featuring the Monts de Lacaune, the Espinouse, and the Caroux massifs. The terrain varies from rugged mountain gorges and heather-covered plateaus to dense forests and lowland vineyards. It is a designated Geopark recognized for its complex geological history, including the presence of ancient metamorphic rocks and coal mining remnants. The park serves as a hub for outdoor recreation, including long-distance hiking (GR trails) and mountain biking (VTT). It is home to diverse ecosystems, supporting populations of mouflons introduced to the Caroux massif in the 1950s. The park headquarters are located in Saint-Pons-de-Thomières, a town historically significant for its Romanesque abbey.

Pack layers even in summer, as temperatures can drop significantly when moving from the lowland garrigue to the high mountain plateaus.
Utilize the designated 'Espace VTT' hubs which provide mapped loops specifically categorized by difficulty levels for mountain bikers.
