What is the best season for canyoning in Annecy?

If you're planning a trip to Annecy and dreaming of jumping into the cool rivers of Haute-Savoie, canyoning is a fantastic idea! But before booking, one question often comes up: what is the best season for canyoning in Annecy?

The answer isn’t as simple as it seems. Depending on when you visit, the experience can be completely different — water levels, temperatures, sensations, and difficulty all vary throughout the season. Here’s everything you need to know to choose the right time and find the canyon that suits you best.

The canyoning season in Annecy: from May to September

In Haute-Savoie, canyoning follows the rhythm of the mountains. The season generally runs from late April to late September, offering around six months of guaranteed adventure. Outside this window, most canyons are either too cold or closed for safety reasons due to snowmelt or autumn floods.

But within the season itself, each month has its own personality.

Month by month: what should you expect?

🌿 April – Mid-June: first jumps, first thrills

From the end of April, the season officially begins. Snowmelt at higher altitudes feeds the rivers of Haute-Savoie, creating generous water levels and stronger flows than in midsummer — perfect for faster natural slides and intensely turquoise pools.

No worries though: the Angon Waterfall canyon is perfectly accessible during this period, both in the Discovery and Sport versions. In fact, it’s often at its most beautiful, with waterfalls flowing at full power.

However, the Montmin Canyon and the Devil’s Bridge only open from mid-June onwards, once water levels have dropped.

Who is it for?Perfect for those wanting to discover canyoning early in the season, enjoy the energy of spring waters, and avoid the summer crowds.

Good to know:Water temperatures remain cool (10–14°C / 50–57°F), but with the neoprene wetsuit provided during your outings with Yoyo Canyoning, it’s absolutely manageable.

☀️ Mid-June – August: peak season, the perfect balance

From mid-June onwards, all canyons are open and the season is in full swing. Water levels are accessible, temperatures are pleasant, and the gorges of Haute-Savoie are at their absolute best.

What you’ll experience:

• Crystal-clear water and pools that are perfect for swimming

• Water temperatures between 16 and 20°C (61–68°F) depending on the canyon

• Generally stable mountain weather (often sunny mornings)

🍂 September: the locals’ secret favorite month

September is often considered the best month by local guides. Most tourists have left, daytime temperatures remain pleasant (20–25°C / 68–77°F), and the canyons regain a peaceful atmosphere.

What you’ll experience:

• Less crowded sites and a more intimate atmosphere

• Early autumn colors appearing in the gorges

• Perfect water levels — neither too strong nor too low

• An unbeatable quality-to-experience ratio

What if the weather is bad?

In the mountains, weather conditions can change quickly. Heavy rainfall upstream can suddenly raise water levels, making certain canyons unsafe or inaccessible — even in the middle of summer.

This is one of the key reasons why going with a professional guide is essential. As a state-certified guide, we monitor weather conditions several days in advance, know the alert levels for each site, and always have backup solutions in case of unexpected changes. Your safety and enjoyment always come first.

If bad weather is confirmed, the outing is postponed or replaced — never simply canceled without alternatives.

My personal recommendation

If you ask me for the absolute best time to go canyoning in Annecy, I’d say without hesitation: the second half of June or the entire month of September.

• Mid-June: water conditions are perfect, all canyons are open, and the atmosphere is amazing.

• September: the peaceful mountain atmosphere at the end of the season is something truly special.

That said, every part of the season has its own treasures. The most important thing is to come well-equipped, properly guided, and with a smile. Use the canyon comparison tool to find the route that matches your style.
