Bisse du Ro and Tseuzier dam

de fr

The climb up the Bisse du Ro to Lake Tseuzier is fairly easy

The return trip is more difficult, with a steep descent at the beginning and a steep climb at the end of the walk

In the middle there is a field with cows, so remember to close the gates behind you

A hike you simply must do.
I set off from Lake Moubra at 8.00 am (1,424 m) in the cool morning air, then headed towards Lake Grenon at the start of the Bisse du Ro.
Along this path, there’s a magnificent waterfall, a footbridge, a dizzying but safe crossing, and yet another waterfall where there’s a resting spot – I’ll head back there on the return journey via a different path, through Chemignon (1,733 m), then on towards Lake Tseuzier, arriving at 11.00 am (1,777 m).
I walked round the lake, passing the waterfall, and enjoyed a hearty snack by the embankment whilst taking in all this beauty.
Retracing my steps above the lake, I headed towards Bise de Lens, which took me back to the waterfall at the rest spot, and then I followed the same path again.
Arrived at 3.00 pm at Lake Moubra.

⚑Departure from Icogne (Valais)
You’ll walk alongside what is probably the oldest bisse. Since 1947, as maintenance had become too dangerous, the water no longer flows through it; it has been diverted. The information boards along the path are well worth reading. The path can be quite impressive as you often follow a platform right in the middle of the cliff face, as shown in one of the photos. Of particular note is a Himalayan-style footbridge – wide but nonetheless impressive, 124 metres long – built in 2020. The route is very well secured. You can extend the walk to the Tseuzier dam and return by bus, or otherwise return via the same route. Please note: given the terrain, the elevation gain shown is significantly overestimated. Expect around 150 metres.

⚑Departure from Ayent (Valais)
The walk starts and ends at the Tseuzier dam. It begins by skirting the lake, then continues uphill tothesmallLac de Téné. The ascent to the pass takes place on a route consisting entirely of rock (the glacier is no longer visible). The descent follows a different path, offering some stunning views, particularly along sections over the sharp limestone pavement (a geological formation).

⚑Departure from Arbaz (Valais)
Starting from the Anzere cable car station this walk follows a piste before heading uphill into an alpine pasture where the path all but disappears, this section is short as you soon pick up a better track to the Combe de Serin and a descend to the alpine pastures at Serin. You then take the waymarked paths back through the forest and beside the Bisse to Anzere. A varied and interesting walk with great views.

Circular Tour of Sex Rouge including the Summit
↔11.73 mi ↗+2,792 ft ↘-5,417 ft ◔7h 50 ▲Difficult
⚑Departure from Arbaz (Valais)
This walk starts in Anzere and uses the cable car to the Pas de Maimbre. The walk takes you around the Sex Rouge and includes the short but steep ascent to the summit for the great views across the Pennine Alps. It descends to pass the Cabane de Audannes and then through the Combe des Andins to Serin. After this is uses one of the established Bisse walks to return to Anzere. ⚠️(Note in 2024 the path between point 2616m and the col at La Selle was affected by a landslide and is unsafe. This route uses a deviation set up by local mountain guides; it is marked with posts but is not yet as obvious as it will be, once it is used by many people)

Walking Tsittoret Bisse (Crans Montana)

⚑Departure from Mollens (Valais)
For fans of bisses (Swiss irrigation channels). A very lovely hike covering part of the Tsittoret bisse. We avoided the first section of the bisse, which we’d been told was steep, by starting our walk from a place called l’Aminona. The walk is generally accessible as it follows the channels, though there are a few fairly steep flights of steps. A few beautiful waterfalls and magnificent views will make this walk truly special. A lovely mix of shaded and rocky areas will help you adapt to this walk whatever the weather. We made a detour towards the Petit Mont Bonvin and returned via the Tièche valley to complete a circular walk. (No. 101211191)

Walking Three Bisses Circular Route starting from Venthône

⚑Departure from Mollens (Valais)
In Valais, ‘bisses’ are irrigation channels built along the mountainside to distribute water from glacial torrents. Walking along the bisses generally makes for easy (little elevation gain) and pleasant walks. The route suggested here combines several bisses to form a circular route: out via the Bisse Neuf and the Bisse de Varen, through the forest; back via the Bisse de Mengis along the edge of the vineyards, passing by the Cascade de la Raspille. This results in a slightly greater elevation gain (as the outbound and return bisses are at different altitudes), but it allows for a greater variety of landscapes along the way.
