New Swimming lake, Aquapark and Accrobranch Park



New swimming lake (free access)

This new artificial lake has a grass beach giving access to the swimming area, which will be divided into four zones: a first one of 0.30 m for the very little ones; a second of 0.60 m for the little and medium-sized ones; a third one of 1.20 m for everyone, allowing ball games; and a fourth one of 2.50 m for everyone allowing diving and jumping from a wooden pontoon. The entire supervised swimming area will be larger than an Olympic-size pool.


Access to the swimming lake: The main access to the swimming lake will be 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 planned on the banks of the Arly.



A giant water playground, the aquapark is a series of different inflatable modules: airbags, platforms, unstable logs, slides, trampolines, etc. 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

Each tree climbing circuit (Kids, Adventure, Xtrem) will have between 12 and 15 workshops each.


The Kids course is reserved for children from 4 to 7 years old: their circuit is between 1 and 2 metres high and parents accompany their children throughout this course.

The Green and Blue course: accessible as of 7 years. Like the colours of the ski pistes, the difficulty increases to prepare for the “red+” course.

The Red+ course: for pre-adolescents, adolescents and adults. In addition to the workshops, this circuit offers 3 ziplines crossing the Arly River and running alongside the lake (the latter one is 125m long).

We will be equipped with a continuous lifeline system, which means that there will be no manipulation of snap hooks along the course, only the spinning of the pulley all along the cable from the beginning to the end of the circuit.


Opening: June 2023 / July-August: daily, 10.00-18,00 / September: Wednesdays and weekends, 10.00-18.00, by reservation during the week. Halloween holidays: daily, 10.00-18.00, weather permitting.
