Dauphiné Prealps (Préalpes du Dauhpiné in French) are a mountain range in the south-western part of the Alps with 394 named mountains. These mountains are primarily located in the Auvergne-Rhône-Alpes region, but also spread into Provence-Alpes-Côte d'Azur (south-eastern France). The Dauphiné Prealps name is derived from the epinonimous former province whose previous area roughly corresponds to that of the present day départements of the Isère, Drôme and Haute-Alpes.
The Dauphiné Prealps consist of the Vercors Natural Park in the west, the Dévoluy Mountains in the east and the Ceüse-Aujour, Diois and Baronnies Massifs in the south.
The highest mountain in the Dauphiné Prealps is the Grande Tête de l’Obiou, situated in Dévoluy Mountains. It is visible from both Grenoble to the north, and Gap to the south. With a prominence of 1,542m this mountain is classified as an Ultra and is ranked the seventh most prominent summit of metropolitan France.
During the winter months, the Dauphiné Prealps are a haven for winter sports enthusiasts, with countless ski-resorts, cross-country, and biathlon trails. During the long summer months, the area's natural beauty attracts road cyclists, mountain bikers, hikers, and hang gliders alike. The gorges of the Vercors, the high alpine peaks of the Grande Tête de l'Obiou and the mountain lakes which area scattered throughout the region make the Dauphiné Prealps a must-see for any outdoor lover!

The lifts in the resorts of Villard de Lans, Lans en Vercors and Corrençon en Vercors on the Vercors plateau are open during the summer to cater both hikers and mountain bikers. Smaller stations such as Gresse en Vercors and the Col de l'Arzelier operate primarily during the winter months.

There are two major cities in the Dauphiné Prealps: Grenoble and Lyon.
Whilst Lyon is the larger of the two, it is also the farther from the mountains. Grenoble is a much more compatible location in this regard. It is ideally suited as a basecamp for not only excursions in the Dauphiné Prealps, but also for the trips to the Savoy Prealps to the north and the Dauphiné Alps to the south.
Grenoble airport is the closest airport to the Dauphiné Prealps and is open all year round, however, primarily catering ski-resorts in the winter, the summer flights are limited to around 3 per day. Lyon airport is slightly farther away, but has a much more expansive destination area with frequent transfers to Grenoble.
