Dorénaz Cable Car

Highlight • Rest Area

The cable car takes you and your bike up to Champex. The wheels hang under the gondola during the ride. Sounds worrying, but it isn't.

A magnificent trail or "singletrail" for English speakers on a balcony with an incredible view of the Grand Combin and Mont Blanc massif, as well as the Rhône plain, 1800 meters below... Turning around, you can also see the Dents-du-Midi.

Super nice vantage point! And the best thing is: you don't have to pedal all the meters up here yourself. The cable car in Dorénaz saves you a total of 650 meters in altitude.

The Portal

Highlight • Natural Monument

This rock gave its name to the place and to the tour that can be done on foot or by bike (with a little portage).

Frequently Asked Questions

How long does it typically take to complete this enduro loop?

The Enduro loop from Portail to Dorénaz is a challenging ride. Komoot estimates the duration at approximately 5 hours and 42 minutes. However, experienced riders on non-electric mountain bikes might complete similar routes in the area in 4-5 hours, depending on their pace and technical skill.

Is this trail suitable for advanced mountain bikers?

Yes, this trail is rated as difficult and is best suited for experienced mountain bikers. The terrain in the Dorénaz region is known for being steep, technical, and rocky, with sections that can include jumps, gap jumps, rock faces, and rock gardens. It's considered a challenging ride with a technical level often rated 4 out of 5.

What is the terrain like on the Enduro loop from Portail to Dorénaz?

Expect a demanding ride on alpine singletracks. The terrain is generally steep, technical, and rocky, characteristic of the Swiss Alps. Riders may encounter natural features such as rock gardens, jumps, and exposed sections. Be aware that some parts of trails in this area have been reported to be unmaintained or have fallen trees, adding to the technical challenge.

What are the best starting points and parking options for this loop?

Given the loop's name, common starting points would be near Portail or Dorénaz. For access to the upper sections, the Dorénaz Cable Car could be an option. Parking availability would depend on the specific trailhead chosen, but generally, you'd look for parking in or near the villages of Dorénaz or Fully (which is near Portail).

What can I see along the route?

The loop offers stunning alpine scenery and notable viewpoints. You'll experience the Portail Singletrack with Views of Grand Combin and Mont Blanc, and from the Portail de Fully, you can enjoy expansive views of the Rhône Valley. The natural formation known as The Portal is also a significant landmark.

What is the best time of year to mountain bike this loop?

The best time for mountain biking alpine trails like this loop is typically during the warmer months, from late spring through early autumn, when the trails are free of snow and conditions are generally drier. While some trails in the Dorénaz area can be ridden in winter, the full enduro loop is best enjoyed when alpine conditions are favorable.

Are there any permits or entrance fees required for this trail?

There is no information indicating that specific permits or entrance fees are required to ride the Enduro loop from Portail to Dorénaz. However, always check local regulations before your ride, especially if using cable cars or private land access points.

Is the Enduro loop from Portail to Dorénaz dog-friendly?

There is no specific information available regarding whether this particular enduro loop is dog-friendly. When mountain biking with dogs in the Swiss Alps, it's generally advisable to keep them on a leash, especially in areas with livestock or wildlife, and to ensure they are fit enough for the challenging terrain and long duration.

Does the trail intersect other well-known paths?

Yes, sections of this route intersect with several other paths. You'll find yourself on parts of the Via Alpina Stage 78: Col du Demècre - Vernayaz, Pont de Dorénaz - Branson - Pont du Rhône, and Chemin pédestre de montagne, région Martigny, among others.

What essential gear should I bring for this enduro mountain biking loop?

Given the difficult and technical nature of this enduro loop, it's crucial to bring appropriate gear. This includes a full-suspension enduro mountain bike in excellent condition, a full-face helmet, knee and elbow pads, gloves, and sturdy riding shoes. Carry plenty of water, snacks, a repair kit, a first-aid kit, and navigation tools. Due to potential unmaintained sections, consider bringing tools for minor trail clearing if necessary.

Are there any cafes or restaurants near the trail for refreshments?

While the trail itself is in an alpine setting, you'll find amenities in the villages at either end of the loop. Dorénaz and Fully (near Portail) offer options for cafes, restaurants, and potentially accommodation to refuel before or after your ride.
