I thought you might like to hear about my website - www.trailbehind.com
- that helps people find great places to hike. We just released a beta
version, and we have some good information in Germany, for example:
http://www.trailbehind.com/#get_map_from_node/4062784

TrailBehind compiles maps of parks and forests around the world, and
links the waypoints and trails to trip reports and other information
on the web. We index reports from sites such as localhikes.com,
summitpost.com, bahiker.com, etc. This week, we're adding wikipedia
data to the map.

The site is set up as one continuous map, with National Parks showing
up at level 4, and more detail as you zoom in. Trail overlays start to
show up at zoom level 14. TrailBehind also lets users upload/download
GPX data, write reports, and link webpages to the map.

If you check the site out and have feedback or bug reports, please
email me and we will fix things right away :)
