De Bise à Ubine is a 10.4 km circular moderate hiking route in Switzerland, starting and finishing at Les Penots. The route covers 701m of ascent and 730m of descent, with elevations ranging from 1,342m to 1,839m. Allow approximately 3h 54m for the full route.
The route is divided into 8 segments. The toughest stretch is the 2.2 km from Mont de Chillon to Pointe des Troisjeans, climbing 359m (allow 1h 03m for this section). In contrast, the 1.5 km from Sur les Saix to Les Penots is much gentler.
About 69% of the trail is runnable, but the remaining steep sections will push most people into power-hiking mode. Some pitches hit 60% gradient, so trekking poles are strongly recommended.
Budget roughly 2,038 kcal of energy expenditure and 2.3 L of water.
Mid-altitude route up to 1840m. Accessible May–October.

Terrain Analysis
Surface & Technicality
Gradient describes steepness, not exposure, scrambling, footing or current conditions. Technical difficulty is unknown where no mapped rating is available.
Tree cover and UV
🌤️ Mixed. Sections above the treeline are open to the sky; lower sections have some canopy. Carry sun protection for the open parts.
Canopy is inferred from elevation against a 2000 m Alpine treeline and from gradient below it, not from observed tree data — treat it as an estimate. It is a different question from the terrain shade above, which is about whether a mountain is between you and the sun at a given time.
Current Conditions
Based on 1991–2020 climate averages, the weather on De Bise à Ubine is usually best from June to October. Snow is likely at the high point (1841 m) in December to April.

Source: TerraClimate 1991–2020 monthly averages. Averages for the area at each point’s elevation (4 km grid, corrected for height). Not a forecast or a report of current trail conditions. These values describe the whole trail's lowest and highest points. Snow at the high point is estimated with a simple snowpack model from these temperatures and precipitation, not observed; steep islands and high summits can hold more snow than it shows. Daylight is for the 15th of each month. Hut, transport and park seasons are separate: check them for your dates.
Averages cannot establish current trail conditions. Check recent local reports, the forecast and restrictions before departure. Snow and ice can persist on shaded sections or arrive outside the usual season.
