The approach from the south is very nice, the descent to the north via the forest road is not allowed, but with great caution and pushing in tunnels possible

Here, you enter a sensitive natural area for a 1-kilometer trail marked with four stations to discover the area's remarkable flora and fauna. A pleasant way to connect the two shores of Lake Paladru, between Paladru and Montferrat.
