Frequently Asked Questions

How challenging is the King Stone Road mountain bike trail?

This trail is considered highly difficult and is suitable only for experienced mountain bikers. It features a massive 1750-meter (6000-foot) descent over a challenging alpine trail, comparable to extreme descents found in places like Whistler.

What is the terrain like on this route?

Expect a crazy alpine trail with rocky, technical, and potentially exposed sections. The high-altitude environment means you'll encounter varied surfaces typical of the French Alps, demanding advanced riding skills.

What are the best times of year to ride the King Stone Road?

The best time to ride is typically during the summer months, from late June to early September, when the snow has melted and the weather is most stable. Always check local conditions and forecasts before heading out, as alpine weather can change rapidly.

Where can I park and access the trailhead for this mountain bike route?

The route begins near Ruillans Station. Parking options in La Grave are available, and you would typically use the Téléphérique des Glaciers de la Meije to access the higher elevations, including Ruillans Station, to begin the descent.

Are dogs allowed on the King Stone Road trail?

As the King Stone Road is located within the core zone of the Écrins National Park, dogs are generally not permitted, even on a leash. It's always best to check the latest regulations directly with the park authority before planning your trip.

Do I need any permits or have to pay an entrance fee to ride in Écrins National Park?

There is no general entrance fee to access Écrins National Park. However, specific activities or areas might require permits, and strict regulations apply, especially concerning wildlife protection and environmental preservation. Always respect signage and park rules.

What notable landmarks or viewpoints can I expect to see along the way?

The trail offers breathtaking mountain vistas characteristic of the French Alps. A significant point of interest is La Pierre du Roi (Summit), which provides expansive views before the major descent.

Does this route intersect with other well-known trails in the area?

Yes, the King Stone Road route shares sections with several other trails. Notably, it covers parts of "La Brèche Pacave depuis La Grave" (83% of its length), "Le tour du pays de la Meije" (59%), and "Le Bois des Fréaux" (50%). You may also encounter shorter sections of "Cote Fine" and "Chavala".

Are there any amenities like cafes or accommodation near the trail?

La Grave, the village at the base of the descent, offers various amenities including cafes, restaurants, and accommodation options. It's a well-known hub for outdoor enthusiasts in the region.

What should I wear and bring for mountain biking this trail?

Given the trail's difficulty and alpine environment, wear appropriate mountain biking gear, including a full-face helmet, body armor, and sturdy shoes. Carry plenty of water, high-energy snacks, a repair kit, first-aid supplies, and extra layers of clothing for varying weather conditions. A GPS device or app like komoot is highly recommended for navigation.

Is the King Stone Road a loop trail or an out-and-back?

The King Stone Road, as described, is primarily a downhill descent. While you start at a higher point (often accessed via lift), the route itself is not a loop. You will typically descend to the valley floor in La Grave.
