The Nahe is a river in Rhineland-Palatinate and Saarland, Germany, a left tributary to the Rhine. The name Nahe is derived from the Latin word Nava, which is supposed to be based upon the Celtic origin for the wild river. So much for the small introduction with wikipedia support. But yes, talking about the wild river in Germany, I think it has earned the name. This river is one of the very last spots in Germany, where the Dice Snake (Natrix tessellata) occurs. In the Vineyards around the river lives another gem: the Western Green Lizard (Lacerta bilineata). I spent a nice day in the beautiful area near Bad Kreuznach.
