There is lots of lovely walking close to Tudor Caravan Park. The Gloucester-Sharpness canal runs alongside the park and this makes up part of the Severn Way and there are lots of well-marked footpaths in the countryside around Slimbridge.
The famous Cotswold Way running from Bath to Chipping Campden also runs through Stinchcomb & Dursley just 4 miles away from the park. Visit the Cotswold Way national trail website here
