This is very difficult to narrow down. Nature has such a variety of faces that all shine with differing beauty. Of the places I have been however I must recommend a bike ride along the Rhine River in Germany. The beauty is that of rolling green hills laced with vineyards. The biking trail travels along a sparkling blue river through this gorgeous country side, passing through villages and rural farms. Not only is it beautiful but thoughts of nobility, chivalry and renaissance over come you as you pass the many castles that seem to cover every other hill top. You can imagine the commerce, war, life that would have ensued in this reagin.
