“One of the most scenically varied and sightseeing-rich couple of hours of cycling anywhere in Britain.” – The Independent

A: Cross the River Avon onto Fieldings Lane.
Please walk your bike across the bridge and give way to pedestrians.

B: Opposite the Roman man artwork is the entrance to Bloomfield Road Open Space, from here you can pop into The Bear, great if you fancy a coffee and cake stop. *1 mile to the Odd Down Cycle Circuit (up steep hill – Bloomfield Road)

C: The ex-railway Devonshire Tunnel is ¼ mile (408m) long and named after one of the roads that it lies beneath.

D: The second, longer Victorian tunnel is Combe Down, which at 1.03 miles (1672m) is the longest cycling tunnel in the UK.

E: On exiting the tunnels continue over the reservoir – look up hill to the right to see Midford Castle.

MIDFORD CASTLE – Once Nicholas Cage’s home, this folly was built in 1775 in the shape of the ace of clubs.

OPTIONAL EXTRA – Before doubling back towards Monkton Combe/Tucking Mill (where William Smith the “father of Geology” was born in 1769), you could continue a little further (½ mile) to the Hope and Anchor for a break and family-friendly food. There is also the option to continue on National Cycle Network route 24 to Wellow (2.5 miles), Radstock (6.9
miles) or further south to Frome (11.9 miles). The surface on these routes is uneven in places, there are hills and some quiet roads.

F: Take a left off the cycle path and head almost back on yourself towards Monkton Combe.

G: After The Wheelwright Arms (a lovely gastro pub) and Monkton Combe School turn right and drop down onto the quiet road leading to the canal.

H: Passing (or stopping at) the potential lunch spot at Brassknocker Basin café & campsite, Angelfish Restaurant, the Somerset Coal Canal (now used for moorings) and Bath and Dundas Canal Company (where you can hire canoes) you will then cross over the canal beside Dundas Aqueduct.\

DUNDAS AQUEDUCT – An impressive grade 1 listed structure built from Bath stone in 1800, it carries the Kennet & Avon Canal over the River Avon. The main arch has Doric pilasters and balustrades at each end. This was the first canal structure to be designated as a Scheduled Ancient Monument in 1951. 

I: In front of The George at Bathampton is a beautiful spot for a picnic, or grab some family-friendly food at the pub. Sometimes there is a barge selling ice cream.

J: Leave the canal path and go up left to the traffic lights on the pavement and cross Warminster road. You can then drop down Sydney Road – you will pass Sydney Gardens and the Holburne Museum on the right.

K: Pass along the Georgian architectural wonders of Great Pulteney Street and Pulteney Bridge (often featured in period dramas and films). You are now back in the heart of Bath where you will find many cafés, patisseries, pubs, restaurants alongside a huge range of attractions.

L: If you wish, continue on to Kingsmead Square – which has multiple cafés for a quick coffee and cake.

M: Join the quiet river path for the final mile.
