The Village of Boudry is about a 20 minute walk from Grandchamp. I don't know much about it except that it is the last stop on the Tram #5 from Neuchatel and has a Chateau, and Art Museum, stores and Coop, a grocery store. I've walked there a few times now and have explored a couple of the roads.
More to come when I get around to it. I've got lots more from around Grandchamp and I went in to Neuchatel yesterday. Be at peace my friends, I am.
