Hi All
I am interested in riding out here as well. Some folks down the street own horses, but they don't rent them.
Lived on a Thoroughbred farm one summer, (horses eating better than people) so appreciate really well cared for stock.
Another friend out in Bondorf (south of Bobligen) tells me the trails always have riders out there, but i need to push him to find some rental riding.
Found this link off the Stuttgart Tourism site, but at 60 euro (almost $100USD) for an hour I will keep looking

Anyone find something they like please share the wealth !
