The route starts at the fantastic Blaise Castle, a 650-acre estate that has a museum, parkland, children's play area and a fantastic castle.
There is a cycle route through the estate, running from Coombe Dingle to the Kings Weston Road.
Blaise is also an excellent starting point for a walk. The estate has an extensive range of scenic pathways packed with great views and points of historical interest.
There are footpath links to Kingsweston Estate and beyond, the community Forest Path, and the Severn Way. More information is available from Bristol City Council.
On leaving the estate, you travel through the picturesque Blaise Hamlet on road before joining the A4108 (which has a designated cycle path).
You travel closeby to Cribbs Causeway so you can detour here for some retail therapy.
Alternatively carry on Route 4 which takes you on road past Bristol's newest attraction, Project Wild Thing. Opened in 2010, its a National Wildlife Conservation Park which is home to grey wolves, lemur, zebra, antelope and red river hogs.
From here the route travels on a traffic-free path close to Severn Beach, an SSSI (Site of Special Scientific Interest) with a diverse range of wildlife from seals to peregrine falcons.
The route then heads for the old Severn Bridge which has a pathway designated for cyclists.
Once in Wales, you continue on the Wye Valley Link Road (which has a designated cycle path) before taking a right-hand turn onto Mathern Road (National Cycle Route 42) which takes you all the way into Chepstow and to Chepstow Castle.
The Castle is found on a clifftop above the River Wye and is thought to be the oldest surviving stone castle in Britain. It boasts the oldest castle doors in Europe at over 800 years old.
