I'm looking for an online map covering central Europe (mainly France, Switzerland, Germany, Italy and Austria), which has on it the most popular natural attractions (lakes, mountains, scenic roads etc...).
Specifically this is for planning a road trip that I'm about to start from Basel, and I need to decide in which direction to drive. I am not interested in cities, only natural attractions.
BTW if you know about maps of this sort covering other parts of the world, this could be useful for other travelers.
