Le Locle

"I could have stayed for an hour longer having my breakfast at Maison Dubois: all these good things on this old clockmaker’s bench; you want to eat and eat and eat.... and go back to bed. But the sun is shining and the plan for the day is to put on our show shoes and enjoy the Grand Sommartel circular trail. I take my courage in both hands and tie my shoes with a few grimaces. An hour later, I’m not sorry: after a good climb to Sommartel, the high point, a magnificent view of the Alps opens up in front of us. The prospect of a lovely hot chocolate when we get back gives me the courage I need to finish the loop at top speed."
