Trail Conditions Fenetre D'Arpette 5 July 2026

As we move into July, the trekking season is now in full swing and conditions continue to improve across the Alps. One of our guides, Vic Chelton, has recently recced the Fenêtre d'Arpette to assess current conditions for those walking the Tour du Mont Blanc and Walkers Haute Route.

Earlier in the season we recommended the Bovine Route as the safer option due to snow and difficult conditions. Following Vic's latest recce, the Fenêtre d'Arpette is now passable under typical summer conditions, although it remains one of the most challenging and technical days on the Walkers Haute Route.

Current Conditions

• The trail from Trient to Col de la Forclaz is in excellent condition.

• The ascent from Col de la Forclaz to the Fenêtre d'Arpette is snow-free and follows normal summer conditions. As always, this is a steep, rocky and physically demanding climb, so an early start is strongly recommended.

• Due to the current heatwave, carry at least 2 litres of water, preferably more. There is no reliable water source on this section.

• Expect to meet plenty of other trekkers travelling in both directions.

• Mobile phone reception is limited throughout much of this area.

The Descent to Champex-Lac

The descent from the Fenêtre remains largely snow-free.

• The first 100 metres of descent are, as always, loose and require careful foot placement.

• There is one remaining snow crossing before the boulder field. It presents few difficulties but care should be taken to avoid holes forming in the melting snow.

• Microspikes are no longer required. A well-defined track crosses the snow and can be negotiated safely with sensible care.

• The boulder field requires concentration—follow the painted waymarks carefully.

• Below the boulder field the trail gradually becomes easier, with only a few straightforward stream crossings that may become more challenging after heavy rain.

Our Advice

Fenêtre d'Arpette remains one of the most technical stages of the Walkers Haute Route. Although current conditions are good, this is not a route to underestimate. It requires good fitness, confident footing on rocky terrain and stable weather.

If poor weather, heavy rain or thunderstorms are forecast, we continue to recommend taking the Bovine Route between Col de la Forclaz and Champex-Lac, which provides a safer alternative in unsettled conditions.

We'll continue to monitor the route throughout the summer and post further updates as conditions change. Safe trekking!
