In an imposing stone and fachwerk (half-timbered) building, this well-run hostel is situated at the start of forest trails 3km from Helmarshausen. There are plenty of indoor- and outdoor-activities (volleyball, basketball, pottery and archery are just some), full board is available and linen is included (but there's a €4.50 surcharge if you're over 27 and come without children).
Take bus 180 to Helmarshausen-Mitte.
