World Heritage "curse"?

Later this summer I'll be biking through a part of the Loire Valley that's been designated a UNESCO World Heritage Site.  The designation, which only occurred about ten years ago, is meant to help preserve, and at the same time draw attention to, the remarkable chateaux along the middle portion of the river, and to their history.  I suppose it's not unexpected that these two objectives should end up creating tensions.  The people who want to draw in tourists and the people who want to preserve sites aren't necessarily the same.  And once the UNESCO designation has been achieved, they aren't likely to have the same interests.  In fact, they may well end up in conflict.

A recent example of this is the Loreley Plateau, a site along the middle portion of the Rhine River, about 80 km west of Frankfurt, Germany.  (Hat tip to M. McDonald)  The plateau is at the top of a nearly 400 foot-high rock at the narrowest point of the Rhine.  The rocks below and the turbulence in the river have caused numerous accidents over the years and helped give rise to local legends.  In 2002, the rock and the plateau were included in a 65 km stretch of the river receiving UNESCO World Heritage designation.

Google Satellite identifies several hotels, restaurants and a sizable camping ground on the plateau, all of which feature great views above the river and probably benefit from the UNESCO designation.  But it seems that a recently-constructed summer bobsled run was one thing too many.

Just this week, the World Heritage Committee issued a statement declaring that the run was "not compatible with the outstanding universal value of the World Heritage property" and calling for its removal.

I'll be on the lookout for tourism run amok when I'm riding past the Loire chateaux.  But I have to say I have trouble seeing this bobsled run as an example.  The World Heritage Committee seems to be okay with places to eat and sleep and park your camper van.  But the bobsled run seems to strike them as just too touristy, too tackily mass touristy.

 I'd probably prefer a beer on one of the restaurant terraces before I took a run on the bobsled.  But it's a little hard to see, from the photo here, how it has more of an impact on the site than do the other tourist facilities.

Meanwhile, commercial barge traffic continues along this stretch of the river below and a little over two years ago one of them capsized near the Loreley rock spilling 2,400 tons sulphuric acid into the river.  One wonders whether the barges and their cargos are "compatible with the outstanding universal value of the World Heritage property?"
