New swimming lake, Aquapark and Accrobranch Course



New swimming lake (free access)


Discover a fabulous new swimming area in Praz sur Arly, facing the Mont Charvin… an exceptional site for a refreshing summer break! A swimming lake supervised by lifeguards with free access for all, isn’t that just heaven? A lake created with two different swimming areas to satisfy all your desires!


ZONE 1: A supervised public swimming area with a surface area larger than an Olympic-size swimming pool! Graduated depths from 0.30cm to 2.50m to satisfy both young and older swimmers… fantastic!
ZONE 2: AND IN ADDITION! An area reserved for water sports activities, where you can enjoy our giant Aquaparc and paddles for hire. A large public beach beside the swimming area, ideal for sunbathing between swims! Life is great at Praz Lac Aventures!

Access to the swimming lake: The main access to the swimming lake is from the Belles Leisure Park via a footbridge over the Arly River.

Thanks to a footpath created right around the lake, accessible to people with reduced mobility from Les Belles or the Cassioz road, users will be able to reach the beach and the reception building in which sanitary facilities, a lifeguard’s room, a storage room, a snack bar and a reception office are planned. They will also be able to reach the Accrobranch tree climbing course on the banks of the Arly.


New: A shuttle service (free) will also give you easy access to the swimming lake : timetable


From 8 July to 3 September: Supervised swimming from 11.00 to 18.00.

Come and discover our giant water playground for up to 60 people! The aquapark for big and small is a series of different inflatable modules:


This sports course allows you to challenge your family and friends in a fun way. If you fall into the water, handles located all along the course allow you to get back up easily. A qualified supervisor is present on the course for the safety of all. Located a few meters from the shore, access to the aquapark is by swimming. It is therefore essential (especially for the youngest) to be at ease in the water and to know how to swim. The obligatory life jackets will be provided by the aquapark team.

Accrobranch Park

We have 4 circuits to suit everyone, with a continuous lifeline system for added safety. What is a continuous lifeline system? For you, it means peace of mind: no carabiners to manipulate throughout the route. All you have to do is slide the pulley from one end of the circuit to the other and, above all, think about… having fun!


Our 3 courses give you access to 4 circuits in total, each made up of 12 to 15 workshops, for a good dose of fun for all the family! The level of difficulty is established in the same way as for the ski runs: Green, Blue, Red and Red +.



This is the Green level course for the very youngest, giving them their first taste of heights on a suspended circuit of between 1 and 2 metres, with some great memories in store!
* accompanied by their parents.



This is a course just like our ski runs, with levels of difficulty ranging from Blue to Red. The difficulty increases as you go along, preparing you for the Red+ course, the toughest! Just a little more effort and you’re almost there!



Designed for pre-teens, teens and adults, this course is rated Red+ for maximum thrills! As well as the many workshops on offer along the way, you can try your hand at the 3 zip-lines crossing the Arly and running alongside the lake… an ideal way to see the panorama from a different angle over more than 125 metres! Go for it!
