Jardin d'altitude du Haut Chitelet, Alpine botanical garden near Hohneck peak in Vosges, France.

The Jardin d'altitude du Haut Chitelet is an alpine botanical garden at 1,228 m on the Route des Crêtes, 1 km south of the Col de la Schlucht in Xonrupt-Longemer. Its 1.5-hectare rock garden displays over 2,500 species from cold and mountain regions, grouped geographically, alongside a natural peat bog and a high-altitude beech forest. The entrance building has pale yellow siding and a sign reading "JARDIN D'ALTITUDE DU HAUT CHITELET".

Professor Camille Brunotte of the University of Nancy created the first alpine garden in 1903 with the Club alpin français at the Montabey farm, north of the Col de la Schlucht; it grew from 120 species in 1904 to 800 in 1914 before World War I destroyed it. In 1954 the Office national des forêts gave the University 11 hectares at Xonrupt-Longemer, and work camps of young French and German horticulturists laid out the rockeries from 1965, with planting from 1966 and the public opening in 1970.

The garden's name comes from the Haut Chitelet, the height above the Col de la Schlucht where it sits. Its beds group plants by mountain range, so the Vosges and Alpine flora are the best represented, alongside species from the Caucasus, Siberia, Japan and New Zealand. The river Vologne rises within the grounds.

The visitable area covers 1.5 hectares along the Route des Crêtes, with the entrance building on the road and the rockeries, peat bog and beech forest beyond it. The garden opens only from June to September, so time a visit to that window. Snow can fall from October to May and annual rainfall reaches about 2,200 to 2,500 mm, so bring waterproof clothing and shoes for uneven, stony ground.

A restored peat bog within the garden features a dedicated boardwalk where visitors can observe this rare ecosystem and its specialized plants up close. This area shows how bog landscapes differ from the surrounding mountain plant communities.
