Stage 3 of the Walker’s Haute Route is the most challenging stage yet, but also one of the most rewarding.
A massive, steep climb takes you up to the top of a mountain pass, Fenêtre d’Arpette, and along the way, you will have fantastic views of the Trient Glacier. It is a hard hike, and one of the toughest climbs on the Haute Route, but along the way you have beautiful views over the valley below.
The second half of the hike is a rocky descent down the opposite of the mountain to Champex-Lac.
This stage is slow going, because of the steep climb and descent. It took us roughly the same amount of time to complete Stage 3 as both Stage 1 and 2 combined.
ALTERNATE ROUTE: There are two ways to hike stage 3 of the Haute Route. Crossing over Fenêtre d’Arpette is the more challenging option but it is also more rewarding, with unbeatable views of the Trient Glacier. If hiking over Fenêtre d’Arpette sounds too challenging, or if storms are in the forecast, you can take the optional, easier route via Col de la Forclaz which is described in The Walker’s Haute Route by Kev Reynolds.
COOL FACT: This stage is also one of the stages on the Tour du Mont Blanc. Those hiking the Tour du Mont Blanc in the “classic direction” will be doing this hike in the opposite direction, starting in Champex-Lac and ending in Trient. This is the toughest stage of the TMB (and it’s easier doing it from Champex-Lac to Trient), which gives you an indication on how much more challenging the Haute Route is. On the Haute Route, you are just getting started and there are several longer, steeper days that will really test your legs.

Walker’s Haute Route Stage 3: Overview of the Trail
To hike the Haute Route, we highly recommend following the trail descriptions in the book Trekking Chamonix to Zermatt, The Classic Walker’s Haute Route by Kev Reynolds. Below we list an overview of the day, so you know what to expect along the way. We also provide advice on where to eat and where to stay. Later in this guide, we list a few tips and trail clarifications to be used with the Trekking Chamonix to Zermatt book.
Trient to Chalet du Glacier
Say goodbye to the little town of Trient as you start Stage 3. The trail begins to head upwards immediately, but the ascent does not become steep until after you pass the chalet. For this beginning section, you will hike in the forest along a wide path. It is possible to keep a good pace here.
First climb of the day…this section is not too bad.
After roughly 230 meters (750 feet) of elevation gain, the trail will flatten out (photos below). It will stay like this for about 2 km (1.25 miles) until you reach the first small refuge (Chalet du Glacier). Enjoy the flat trail while it lasts, as you have a tough day ahead of you!
Trient Glacier comes into view just before you reach Chalet du Glacier.
Chalet du Glacier is a small restaurant and it is likely not serving meals until mid-morning or later, but you can buy a small snack and use the restroom here if you need to. We started the hike at 7 am and reached the refuge just past 8 am.
Chalet du Glacier
Chalet du Glacier to Fenêtre d’Arpette
Here it comes, one of the steepest climbs of the Haute Route!
Beyond the refuge, the climb immediately begins its steep ascent and it remains this way the whole way up to Fenêtre de Arpette.
The trail alternates from steep, rocky climbs in the woods to steep ascents on gravelly slopes. At times, you will do some rock scrambling, climb a long series of very steep steps, or use ropes when the path narrows and gets slippery.
Stairs and ropes along the trail.
You will arrive at a very small cabin along the trail which makes a great stop to take a break and enjoy the view of the glacier.
You can also see the location of Fenêtre d’Arpette.
The trail heads uphill from the valley to wall of rocky pinnacles to the far left of the glacier. As you get higher on the trail, you will be able to see a small notch (the window or fenêtre) which you will reach at the high point of this stage.
The climb may be tough, but it sure is pretty! Below is the beautiful valley that you had hiked from and off to the right is Trient Glacier. Beyond, large mountains fill the horizon.
The temperature is also very nice on this portion of the hike, especially if you are doing the climb in the morning. Cold air was blowing off of the glacier and the sun had not yet risen above the mountains, so the chilly breeze and the shade helped keep us cool, despite the fact that we were doing a very strenuous climb.

The final climb to the top is a rock scramble over small boulders. It looks menacing after the climb that you have just done, but it is truly just a short way to go.
Final climb to the top.
Once you reach the top, take a rest and enjoy the view! We ate lunch up here, although it was very windy. If you want to escape the wind, you can begin the descent (as it is warmer on the opposite side of the mountain) and find another spot to rest.

This is the view looking east and towards the descent.
Fenêtre d’Arpette to Relais d’Arpette
The descent begins very steep and rocky, making progress down the mountain very slow-going. The sun was also shining brightly on this side of the mountain which warmed us up very fast.
Have care here. The gravelly trail is very slippery and at times you will be hiking across fields of boulders. It’s easy to stumble and fall, especially with legs tired from the big ascent up to Fenêtre d’Arpette.
The beginning of the descent is the steepest part, although it will remain steep until you reach the valley.

Looking around however you are treated to more epic views. Straight ahead you can see layers upon layers of the Swiss Alps. And behind you is the crazy steep trail switch-backing down from the saddle.
Another view looking back up the trail to Fenêtre d’Arpette.
Eventually the trail becomes less steep and easier to hike, but it’s always rocky so you always have to watch where you are putting your feet.
Eventually you will reach a wide gravel road. First two small farm buildings will come into view. Pass these buildings and the from there Relais d’Arpette is only a 5-minute walk away. We stopped at the restaurant to rest our tired feet and eat a delicious lunch.
Relais d’Arpette to Lac Champex
From here you are nearly to Champex-Lac (about 30 minutes away) and the trail flattens out much more. You will mostly be hiking through a forest in the shade which is a great escape from the summer heat.
Once you make it to lovely Champex-Lac, check into your accommodations. If you still have energy left, you can go paddle boarding on the lake.
Where to Stay in Champex-Lac
We stayed at Hotel Mont-Lac, a wonderful hotel that overlooked the lake. This was one of our favorite accommodations on the Haute Route.
We had a two-bedroom apartment with a living room, kitchen, and a bathroom. We also had a large balcony with a grand view of the lake. The washing machine was perfect for washing our clothes after several days of hiking.
The hotel serves breakfast and dinner. The dinner was delicious (salad, lasagna, and a lemon tart). Breakfast was a buffet of meat and cheese, yogurt and granola, fruit, croissants, and fresh bread.
Hotel Mont-Lac Champex

In Champex-Lac, there is a grocery store and ATM when you first walk into town.
Other alternative hotels we considered were Hotel du Glacier, Hotel Splendide, Hotel Au Club Alpin, Hotel Belvedere, and Hotel Alpina. Hotels Splendide, Belvedere, and Alpina are located on the far eastern end of the lake, a little bit beyond where we stayed.
For a detailed list of accommodations for each stage, along with information on making your reservations, see our guide on How To Book Your Haute Route Accommodations.

Clarifications for the Walkers Haute Route book
We were able to follow the Walker’s Haute Book by Kev Reynolds (the sixth edition from 2019; there is now an updated version) without any issues, meaning we never had to backtrack. But there were a few times during this stage we felt a little more clarification would have helped so we are providing that clarification here. These notes were taken related to following Stage 3 and not Stage 3A.
Finding the Trailhead in Trient: At the “Trient, Betty” bus stop (as labeled on Google Maps) there is a sign pointing to La Forclaz. We followed the direction of that sign which took us along the paved road Le Gilliod (as labeled on Google Maps). We passed the church, which was on our right, and it didn’t take long until this road ended at a main road. We turned right onto this main road and followed it until we came to a gravel road on our left. There is a signpost here indicating mountain biking trails and hiking trails. There is also a large sign board that reads “Ancienne Route de la Forclaz”. This is the trailhead and you want to follow the gravel road. Note that at the trailhead we did not see a sign pointing to “Sentier du Bisse-Glacier” as the book indicates and sadly the stone cross the book refers to was broken and lying on the ground. See the photo below.

Starting the Hike: From the intersection of the main paved road and the gravel road, follow the gravel road a short distance until it splits. At the split turn right to stay on this gravel, rocky track up the hill. It will eventually turn into a grass track as you ascend. Keep following this until you reach a crossroads of trails with a trail signpost. The book refers to this as a “junction of tracks”. Continue straight here following the direction of Chalet de Glacier as indicated on the signpost.
Chalet du Glacier: As you approach this chalet and when you leave, you do not need to cross any of the bridges that go over the Trient River. As you continue on the trail from the chalet it will not take long until you come to a signpost pointing in two directions (Glacier du Trient and Fenêtre d’Arpettaz). Follow the direction towards Fenêtre d’Arpettaz.
Lower Valley: During the descent you will eventually reach the lower valley and be in the trees for a bit. You will come out of the trees onto a wide gravel track with a signpost. Turn left following the direction indicated for Champex-Lac. Following this gravel track downhill will take you past the farms mentioned in the book.
Relais d’Arpette: As you descend past Relais d’Arpette you will see a footpath on your left. It is marked with a signpost. Turn left onto the footpath following the direction indicated for Champex-Lac.
Chairlift: Once you get to the chairlift referenced in the book, Google Maps can be helpful to route you to your place of accommodation.
