We will be vacationing near St. Malo in August and want to meet our friends for an afternoon somewhere between St. Malo and Roscoff for an afternoon. They are arriving by ferry from Ireland in Roscoff.
Where would you recommend two families with teenagers should spend an afternoon together. Probably nothing too strenuous as they will have spent the night on the ferry. Both our families will have cars; they will rent in Roscoff.
