The wonders of TPM

Most of the participants of the TPM are seduced by the splendid setting of the territory. Let’s take a closer look at the most beautiful sites crossed by the routes!


The Monteynard lake is an articificial lake. It has been created in 1962, when the EDF Dam has been constructed in Monteynard Avignonet in order to make use of the hydroelectric potential of the river Drac. The Dam is 25km South from Grenoble, it is at 500m height and measures 135m high for 230m long. Its width is 5 m large on the top and 20m large on the bottom!

Thanks to the Dam, a 16km long lake had been created in 1962. The power station is ran from the Hydraulic management center in Lyon. There are staffs checking regularly the equipment.

The total power of the power station is 360MW and its yearly average production is 460 GWh, which is equivalent to the consumption of a 200 000 inhabitants town! This production is a 100% renewable energy that avoid the emission of 398 400 tons of CO2 yearly.

Unique footbridges in Europe!

Those footbriges are exceptional! Their length is very impressive, Drac river footbridge is 220m long and goes up from 45m to 85m high from water level. Ebron river footbridge is 180m long and goes up from 45m to 85m high from water level.
