Do you dream of glaciers, steep-walled valleys, and nights under the stars… but don’t have a car or would rather take the train? Good news: the Écrins National Park, nestled in the heart of the French Alps between Isère and Hautes-Alpes (between Grenoble, Gap, Briançon, and Oisans), it's high mountains at its most spectacular: legendary peaks, rare biodiversity, untamed valleys, Alpine culture… and part of it is accessible by train and bus!
So, if you're wondering how far you can go without a car (and wearing hiking boots), you've come to the right place. Here, we'll explain everything you need to know to plan your trip to Écrins National Park: How to Get to the Écrins by Train and Bus, the mandatory regulations rules to follow within the park (and why they are essential), Where and How to Stay in a Mountain Hut, and of course: what to do, where to go, and how to make the most of it without a car. Follow the guide.
Established in 1973, the mountain range protects nearly 93,000 hectares in the “heart of the park”, in the middle of 7 Alpine valleys. Here, in just a few kilometers, you go from Mediterranean south-facing slopes the Embrun side of the glacial landscape of the Barre des Écrins (4,102 m), the highest point in the park. There are about 2,400 plant species (more than 200 of which are considered rare or endangered) and a rich variety of wildlife: mammals, birds, reptiles, amphibians, insects… in short, a true open-air laboratory of life.
The territory is divided into two main areas:
There is no train station called “Parc national des Écrins” per se. However, there is several train stations serving as gateways around the mountain range, and then the bus and shuttle networks that take you into the valleys.

In practice: Take the train to one of these stations, then take a bus or shuttle up the valley you're interested in. Except for the Argentière-Les-Ecrins station, where you can get off the train and start hiking right away (and if you don't like steep climbs, there are also shuttles that will take you higher up). More info here.
The train service ends at the bottom of the valley, It's the buses that connect us to the mountains.

In short, the best way to explore the Écrins without a car is to take the train to the nearest station, then a bus or shuttle into your valley.
Before buying your ticket, take the time to plan your trip:
“Okay, so what am I supposed to do without a car?” Here are a few ideas for places you can reach by train and bus to enjoy the mountains.
Train to L’Argentière-les-Écrins, then bus and shuttles to the villages of Vallouise and the high-altitude sites (Pelvoux, Pré de Madame Carle), depending on the season.

A Deep Dive into the Heart of the Vallouise-Pelvoux mountaineering village, historic base camp for mountaineering, rock climbing, and hiking. The hamlet of Ailefroide, which is inhabited in the summer, serves as a starting point for legendary mountain huts (Écrins, Sélé, Glacier Blanc, Pelvoux, Bans…).
Since Madame Carle's Meadow, you can get closer to the the Blanc and Noir Glaciers Follow the marked trails to see the ice giants—or, if you’re accompanied by a guide or are experienced, venture even further into the high mountains!
If you have a few days ahead of you, you can take a multi-day loop, like this 4-Day Hike Through the Mountain Huts of Vallouise, or even this Tour of the Pays des Écrins in 3 days (starting right at the train station, with no additional shuttle).
Train to Gap then take a regional bus to the Champsaur–Valgaudemar Valley, followed by summer shuttles to go further up the valley, notably to the Valgaudemar shuttle which runs in the summer between Saint-Firmin (served by the T91 line (from Grenoble or Gap) and Gioberney.

The Chapelle-en-Valgaudemar is one of the 7 Mountaineering Villages. It is located in the Valgaudemar Valley, sometimes nicknamed the “Little Himalayas” because of its steep, enclosed terrain and peaks over 3,000 m. You can explore the area on day hikes or go on multi-day treks to several mountain huts: Gioberney, Olan, Vallonpierre, Clot Xavier Blanc, Pigeonnier, Charbounéou, Souffles…
In short: torrents, vertical cliffs, large glaciers above the valley… And all that, without a car!
If you have a few days to spare, you could, for example, explore the Tour of Old Chaillol, or the loop around the 4-Day Hike Through the Mountain Huts of Valgaudemar.
Train to Grenoble or Briançon, then regional buses (express lines such as Zou 55 or 69 / T75 (depending on the season) that cross the Lautaret Pass and serve La Grave and Villar-d’Arène.

On site : You're in two mountaineering villages iconic, at the foot of the Meije. A cable car takes you up to the glaciers, and numerous trails lead to mountain huts (Golèon, Pic du Mas de la Grave, Fay, Mouterres, Clots, Évariste Chancel…). The Zou 55 Bus: Grenoble–Briançon serves the Lautaret Pass at 2,058 m. From there, you can Go hiking right near the heart of the park (and take the opportunity to visit the famous Lautaret Botanical Garden)!
In short, the perfect setting for switching things up hiking, exploring mountain heritage, and why not a Guided Introduction to Mountaineering.
Train to Grenoble, bus to Bourg d’Oisans, then specific lines that run up the Vénéon Valley to Saint-Christophe-en-Oisans or La Bérarde depending on the season.
La Bérarde, an iconic village in the Écrins Massif, was affected by a major natural disaster in 2024. The Vénéon Valley is gradually regaining its vitality, offering spectacular scenery, accessible hikes, and shuttle service. For safety reasons, the village remains closed, and the trails bypass it. A dedicated page on the Tourism Office's website provides regularly updated information: be sure to check it before your visit.

Saint-Christophe-en-Oisans covers a large part of the heart of the Écrins. You can visit the “Memories of Mountaineering” Museum, meet some guides, and set off toward a whole string of shelters (Selle, Soreiller, Lavey, Alpe du Pin…).
Once you've set foot in the mountains, sleep up there is often what turns a trip into a true mountain experience.
The Écrins National Park has about 40 shelters approximately, some of which are certified National Park Spirit (a certification program that recognizes organizations committed to environmental sustainability and regional development).

A few things to keep in mind:
In short: a shelter isn't a hotel. It's a “ship at sea” where the caretaker is the captain. You come for the shared experience, the simple lifestyle, and, of course, the sunrise over the peaks.
And to find all the mountain huts in the Écrins National Park, you can check out this interactive map of mountain huts.

The campsite It’s the stuff of dreams: your tent facing the mountain peaks, the sunrise over a high-altitude lake… But in the heart of Écrins National Park, The rules are very clear :
On some high-traffic websites, such as the Lake Muzelle or the Lake Lauvitel, some mandatory camping areas are established to limit trampling.
Near mountain huts, the best approach depends on the facilities and options available on site. You should ask the caretaker (either by phone in advance or when you arrive) about the on-site procedures. Sometimes, it’s possible to sleep near the shelter, use the facilities and even eat meals at the shelter (by reservation only), and sometimes not.
On the major hiking trails, it is sometimes possible to camp less than an hour from the parking lots (but this applies mainly to backpacking hikers arriving from far away).

You can also alternate between camping, mountain huts, and trail lodges on a typical long-distance hike GR54 (Grand Tour of Oisans and Écrins), to manage the showers, the weather, and the food and drink stations.
The park rules aren't there to annoy us, but so that the Écrins remains a vibrant, wild, and natural area, where we can return in 10, 20, or 30 years.
At high altitudes, life struggles with long winters, poor soil, and rapid climate-related changes. It is precisely this rich diversity of habitats and species which led to the creation of the National Park and requires us to limit our impact.
The Park has developed a “Best Practices to Know When Exploring the Mountains” which translates the rules into concrete actions. In short, in the heart of the park:
In short, whenever we ask ourselves, “Why is this forbidden?”, the answer is almost always fauna, flora, soils, safety (or all four at once!). And for the detailed regulations, It's here.
Regulations at a Glance - © Ariane Fornia, Écrins National Park
The restrictions in the heart of Écrins National Park are not intended to make hiking more difficult, but to preserve an area that is home to nearly 2,400 plant species and wildlife that is particularly sensitive to disturbances. Why are dogs prohibited, even on a leash? Why can a simple apple core be a problem? Why is backcountry camping allowed but campground camping prohibited? The Écrins National Park answers each of these questions in its Comprehensive Guide to Regulations, which explains the meaning of each rule and the best practices to follow before setting out.
A successful outing often depends on what you do the day before (or even at home before you head out to catch your train!):
That's what will let you enjoy yourself to the fullest, without putting yourself in danger or calling for help unnecessarily. For more information, visit this page.
Beyond the peaks, the Écrins National Park is also villages that keep mountain culture alive very strong.
The 7 Mountaineering Villages highlight a history tied to mountaineering, a well-preserved architectural and landscape heritage, and a commitment to promoting responsible, locally rooted mountaineering—a practice that has played a major role in the history of the mountain range.
These seven villages are:
