Seit 2013 gibt es die „Entdecker-Runde Kassel“ - einen 48 Kilometer langen Radweg durch die äußeren Stadtteile Kassels. Er führt sowohl zu bekannten als auch weniger beachteten Sehenswürdigkeiten und Naturschauplätzen. 

This is a 48km bike path around Kassel, established in 2013.

The route uses every main hiking route on Mt Sunapee. 

I started from the end of the access road to the Sun Bowl ski area, parking at the gate and walking 400 yards to the base of the Rim trail.

Up Rim, down Newbury, along the railway and mountain road to the Andrew Brook to Lake Solitude, down Goshen Trail, along to old Providence and down ski runs to the base of Summit trail, then to the Summit and follow the SRK route along the ridge back to Rim and back down to the Sunbowl.
