A program 100% created by Gravel Up

The discovery of the Grands Causses bikepacking, that's the program!

The appointment is given at our base camp, on the heights of Millau. Ideally located at the crossroads of the Tarn and Durbie valleys, but above all with a direct access to the different limestone plateaus called Causses - there are 7 in all! But we promise not to do them all... not this time!

Handling of the Gravel the 1st afternoon with our local partner Wish One which manufactures the bikes on the spot! We take the time, we prepare ourselves physically and mentally for the next 4 days which are going to be rich as well sporty as culturally! It doesn't look like that but the physical challenge will be there, we promise you that!

Each Causse is different: forests, windy plateau or ancient templar cities, we promise you a total change of scenery. You will discover the people who make this territory alive, as authentic as welcoming, and whose culinary specialties will not leave you indifferent.

After having crossed the Black Causses and the Larzac, we will take you to the heart of the Rougiers de Camarès. There, it is not the great American spaces but rather the Australian red center which awaits you. An incredible ochre earth awaits you and historical villages of all beauty will make you travel in time.

We will close the adventure with a superb moment of sharing to realize the experience lived on the bike and the strong links that we have built together.

We promise you the discovery of a breathtaking "Land of Gravel", a truly ideal playground that makes us understand why the International Cycling Union (ICU) has decided to organize the French round of the next World Gravel Championships here!

Preparation & equipment


We select for you local guides, passionate about their territory.

Bike mechanic, bike shop manager and even eco-guard on the Larzac plateau, our guide is the best person to help you discover Grands Causses. Anecdotes, encounters and sharing of experiences, he/she will make sure that you have an unforgettable stay and above all that you soak up as much as possible of this fabulous territory.

Spoken languages: French, English

State certified for bike guiding (BPJEPS), he/she will make sure you are safe and will share with you various tips and tricks on how to ride the Larzac or Causse Noir trails.

Gravel Bike

In this destination, you will be able to ride the SUB Gravel from our partner brand Wish One.

The Wish One SUB is the brands first Sport Utility Bicycle. That’s a gravel bike to you and me. But it’s a moniker that we think covers the gravel bike genre better than ‘Gravel Bike’. No matter where you ride, perfect asphalted roads, smooth or dirty roads, gravel sections… the Wish One SUB is developed for ultimate performance.

Handmade in France by Cyfac International using lightweight Columbus HSS Spirit tubing, the Race Type Geometry of the SUB claims to deliver quick and direct handling. It is no relaxed and slack angled gravel cruiser, the SUB is a scalpel sharp race machine designed for dropping lap times and opponents.

eGravel bike

On this destination you will be able to ride the eGravel 3T Exploro RaceMax Boost (or equivalent).

The Exploro Racemax Boost e-bike is perfect for gravel & all-road riding. It’s light yet tough, agile yet planted and fast yet fun.

This makes the Racemax Boost a great range-extender on your gravel adventure. Or it can help you keep up with faster friends on road and gravel rides.

The RaceMax Boost feels every inch the same as the standard RaceMax, with one difference – when the dirt road heads upwards, you can add extra boost for greater traction, this additional power keeping you pedalling up trails you’d otherwise have no right to be riding.

Physical preparation

The territories we cross offer an environment that can sometimes be demanding depending on the weather conditions. We evolve in a mountainous landscape where the cumulative difference in altitude can quickly be important.

To get the most out of this expedition, we recommend that you practice an endurance sport such as jogging, swimming or cycling several times a week. Having already done long bike rides of at least 4 hours will allow you to feel more comfortable and better enjoy the breathtaking landscapes you will cross. At least 2 days in a row of cycling experience is a plus.

Use of automatic pedals is mandatory, ability to maneuver the bike on all types of terrain and good braking technique.


The complete list will be sent to you a few weeks before your expedition. You will find here the few essential items that you may not have at home:

  • Cycling shorts with chamois to be more comfortable

  • Bike gloves to avoid blisters

  • Cycling shoes

How to get there ?

  • By car : Meet us directly at our base camp "Domaine de St Estève".

  • By train : Montpellier train station

As soon as you arrive, our teams will take care of you and drive you directly to our base camp where the beyond biking experience takes its full meaning. The disconnection can begin, do not worry about anything, we take care of everything!

On your first day, we will meet you at 3pm.

And for the last day, plan a departure from our base camp at 12pm.

Another way to discover beautiful landscapes by bike. A great team. Services (accommodation, meals, supervision, logistics, cycling ...) up to expectations. A big thank you to the whole GravelUp team!

Jean-Luc R. - May 2022

I was won over by gravel riding! The versatility of these bikes is fantastic and the bikes offered by GravelUp are just great. Accelerating on the trails, letting loose on the climbs, skidding on the descents and enjoying the beautiful views. The tracks chosen were great, balanced, challenging ... in short, it was fantastic! All this in a great atmosphere where the group and the organisation were one!

Sébastien C. - May 2022

A stay beyond my expectations and those of my 8 companions. A magnificent interlude, an ideal setting to discover the practice of Gravel. Alternating roads and paths in a wild green setting. We only came across a handful of walkers and no cyclists! Nature in its purest form. Professional supervision, always smiling and extremely dynamic.

Eric D. - May 2022

Gravel Up in Grands Causses was awesome! Unforgettable experience and guaranteed change of scenery in this French region, off the beaten tracks. The organization of the trip was perfect and the team very professional and always there to make sure we had an amazing time. Looking forward to my next trip with GravelUp!

To ride in the Causses with GravelUp is to take paths from oneself to oneself through others, and to return with new eyes.

Christophe B. - May 2022

"GravelUp is fantastic!

It was a discovery for me and I will remember it forever. Go ahead and book your stay with friends at GravelUp! An experience, a feeling of freedom, the discovery of a sport and a region. I will be preparing for Corsica in 2023!

Fabien D. - May 2022

GravelUp is the best of gravel served on a plate! Top-notch logistics and organisation! I just had to pedal on dream tracks with a small group who share my passion. A week in a very good atmosphere and a Gravel spirit!

Gravel Up, our expeditions to explore Aveyron and the natural park of Les Grands Causses, a gravel paradise.

Our team have come up with three expeditions to keep everybody happy, from regular social cyclists to bikepacking fanatics.

Between 3 and 7 days riding crisscrossing the natural park of Les Grands Causses in Aveyron on a gravel bike with a group of like minded riders will allow you find landscapes and views that will take your breath away. GravelUp takes care of everything during the trip, from carefully chosen accommodation to local meals and snacks ideal for a days riding.

It’s not just this care that makes our expeditions unique, its the local knowledge of our guides and the chance to visit local people and places that make for genuine and beautiful picnic spots and overnight stays. All that’s left for you to do is choose which of our trips to start with and get your gravel bike ready for an unforgettable adventure.
