We hiked another 1.75 miles, thinking we were going in a circle and would end up back at the intersection of the two trails (my fault, poor map reading and poor planning). Instead of reaching the intersection, we came to a parking lot. Some nice French people were there with a map and we realized we had gone way further than we intended to and we had to hike all the way back. The entire hike ended up being over seven miles, hardly ever on flat ground but up and down the whole way. There were many places where we were literally climbing up and down rocks for long stretches of the trail.
I was so glad the cabin had a nice shower and food and bed waiting!
