So beautiful and so peaceful. It looks like a painting. All those trees in the background, such a beautiful green. An oasis.

Beautiful peat bog, reminds me of Scotland, where you often walk on granite peat. It vibrates under your feet. Two photos show my stick with the tip of it in it, and also all the way in. The peat is quite thick here. Beautiful vegetation, and lizards can be seen too.

The raised bog is a wonderfully tranquil place. One path leads along the moor to the south, another from the northeast a few meters into the bog. Depending on the angle of the light, the otherwise green moor grass shimmers red. Unfortunately, there is no bench here—it would probably sink—but even standing here, you can enjoy a break and let your gaze wander over the moor.

⚠️ There is only one major road (currently closed for construction for part of the length in June 2025), with no sidewalks or protected pedestrian areas. Currently not a problem due to the closure, but would not recommend this route to runners if the road were to reopen.

The initial tidal wave was reportedly up to 40 meters high and traveling at speeds of 70 km/h. It first reached the hamlets of Malpasset and Bozon, which were completely destroyed. About 20 minutes after the wall broke, it reached Fréjus, where the wave was still three meters high and buried large parts of the town in mud.

The dam wall collapsed suddenly and completely on the night of December 2, 1959, at 9:13 p.m. The exact time of the collapse could be reconstructed because it is known when the power was cut off by the flood wave. The wall was almost completely eroded by the force of the water. Only a few sections of the wall on the right bank (as seen in the direction of flow) remained standing. Fragments of the wall, some the size of a house, lie scattered over a distance of several hundred meters downstream.
