アヴァロンの天然記念物・トップ5

Nice path, but be careful, some sections are not very visible with the autumn leaves, plus the path can be technical in some places with uprooted trees and rocks.

The Dionne pit is a karst source called the Vauclusian source, located in the city center of Tonnerre. It is fed by the infiltration of precipitation into the surrounding limestone plateau as well as by the losses of at least one river. The Dionne pit is remarkable for its flow and the size of its hydrogeological network which extends to more than 40 km. His presence is at the origin of the creation of the city of Tonnerre. An elaborate washhouse was built around the spring in the 18th century. Wikipedia

A real must-see - this round wash house around a turquoise green source is unique in its kind and well worth the detour.

The mystery of this pit is complete. The city was built around it.

This cave is one of the many caves dug by the Cure. These are perhistoric caves that contain many paintings dating back more than 33,000 years.

In this gentle valley, you will hear the soothing sounds of the Cousin River babbling as you walk under the canopy of the trees. Bathed in lush greenery, this walk is a real treat.

The Rocher de la Pérouse is 556 meters above sea level and offers magnificent views of the Cure valley. Consult the orientation table to find out more about the view available to you.

The Dionne pit is a karst spring known as the Vaucluse source. It is in fact a resurgence located in the city center of Tonnerre. His presence is at the origin of the very creation of the city. It is fed mainly by the infiltration of rain in the neighboring limestone plateau. The Dionne pit is remarkable for its flow rate with an average of 300 liters per second. Its underground network extends to more than 40 kilometers, and we still do not know its depth. Access to the source is free. For your stay in Tonnerre, I suggest the excellent hotel-restaurant l'Abbaye Saint Michel which nicknames itself "stage boudoir".
