Hundreds of trails weave through the mountains surrounding Grenoble, several only accessible through villages nearby. But planning a weekday getaway hike can be a challenge without a car, as most of the buses out to these trailheads only run on the weekends outside of the summer holiday and winter ski months. There is one trail, though, that takes you up and away from civilization to the highest peak in the Chartreuse mountain range: the hike up to Chamechaude that starts in Le Sappey-en-Chartreuse.
At 9 miles, hiking Chamechaude is a pretty straightforward day hike for the intermediate or experienced hiker, though the uphill may take you a bit longer if you haven’t hiked in a while and the top might be challenging if steep slopes and sheer edges make you nervous. We took our time and the whole hike took us around 7 hours. We didn’t need any special equipment; just food, a few liters of water, and sunblock. We also picked up a map at the Grenoble Tourism Office (Office de Tourisme Grenoble-Alpes Métropole).
We wake before dawn to catch an early #62 bus to Le Sappey-en-Chartreuse, and in minutes we have left the city for behind. The bus trundles along on a neatly paved two-lane road and we watch as dawn spills across the swelling hills and forests. Near the end of our ride, we see a steep cliff jut from the landscape to the left. This is Chamechaude, what we’ll be climbing today.
The bus drops us off in the center of town, less than half a mile from the trailhead. The morning chill has yet to dissipate, so we zip our jackets and start hiking to warm up. The path immediately slants upward, and with few exceptions, will continue uphill for the next several hours.
The first part of this uphill hike is through thickly wooded forests, and wayfinding is made difficult by the profusion of trails sliced through the forest, a combination of hiking and ski trails marked with heiroglyphic patterns of colors. We imprint on our trail’s symbol of a red and white flag and follow it, learning on the way that an ‘x’ in these colors means don’t go this way, it’s not the same trail. I’d wager in the winter these ‘x’ symbols also mean “Do no enter. Downhill only.”
An hour into the hike, the forest thins and we break into a broad meadow at the foot of Chamechaude’s steep side. Chamechaude is on this side is a sheer cliff of a massif, a deformation in the Earth’s crust that might be made if someone dropped a cosmic sized bowling ball onto the ground. Climbing it from here is not a hike but an actual climb, and we’re not equipped for that.
Instead, we follow the trail to the left and around the back of Chamechaude, once again into forest, across small streams and through handmade livestock gates maintained by those who still graze their flocks here. There are even signs asking that we not disturb the cows and sheep.
Finally, we find ourselves on the other side of Chamechaude, a steep but climbable slope cut with a narrow switchbacked trail. Three hours after we began our uphill hike, we begin to hike uphill in earnest, planting one foot in front of another, plodding up and scrambling over small piles of limestone rock. I pick one up to examine it and find traces of fossilized clam and snail shells. This area is a protected park, so I put them back.
While in distance summiting Chamechaude should be only a mile, it takes us more than an hour to climb. We’re exposed here, above the treeline, and are thankful for extra sunblock as the noontime sun glares down on us. But we rest only at the top, heaving and sweating. Was the climb worth it?
Downhill, while precarious, slips by faster than the uphill and we are back at the foot of the mountain in forty minutes. We take the long way back, savoring the cooling shade of the evergreens and brilliant colors on the deciduous trees in the forest. It’s 5 pm and the day is done by the time we again reach the town center of Le Sappey-en-Chartreuse, and we’re just in time for sunset on the bus ride back to Grenoble.
