Rolling Along the River ep2. Captain Mainwaring to Nun's Bridges 

Nun's Bridges in Thetford, also known as the Three Bridges, is a beautiful area by the Little River Ouse. I recommend you have a look.
You can take any type of mobility scooter or, wheelchair along these paths
The paths along the river between Bridge Street and Spring walk are accessible to anyone, if on foot, wheels, stick or horse!
It is a lovely walk or scoot for most people and great for dogs, and The BTO (British Trust for Ornithology) is at the end.
The BTO can give you access to the Nunnery Lakes Reserve if you are feeling adventurous.
If you can, I highly advise you to check it out.
