This short walk takes you south along the old coaching road that once provided the main route between North Mymms and South Mimms. It opens up into a rural valley surrounded by rolling wooded hills and includes footpaths edged by hedgerows rich in wild flowers. There is an option near the end for refreshments at The Woodman Inn at nearby Water End.

Note: There is an interesting variation of this walk which focuses on the fascinating geological features of this walk. It’s on the North Mymms History Project and is titled The natural history around Water End, Hertfordshire. You might want to read it before you set off on this walk. It includes maps and directions, too.


1: There are parking opportunities along St Mary’s Church Road (https://w3w.co/veal.spike.reader). Head SSW along St Mary’s Church Road for 500m.

2: At the point when the lane turns sharp right, your way is straight ahead, through a gate and along North Mymms bridleway 2. After 290m ignore the footpath on your left and continue heading SW as the path begins a steady climb through Cangsley Grove.

3: After 500m you will emerge from the woods with open views across the secluded Potwells Valley (location - https://w3w.co/output.chips.navy). Turn right on North Mymms bridleway 90 then head SW for 130m at which point the track you are on becomes Ridge bridleway 44. Continue SW for another 220m before heading S with the hedgerow on your right and field on your left for 70m until you reach a gate on the right (location - https://w3w.co/owls.speeds.last).
* At this point you could take a slight detour by going through the gate and taking Ridge bridleway 10 through the woods and continuing WSW for 600m with the woods on your left and fields on the right for 600m to a view point (https://w3w.co/still.entry.spends) where you can enjoy views to the W towards St Albans. The viewpoint is marked with a blue icon on the maps above and below.
4: If you don’t take the detour head SSE on Ridge bridleway 10 for 360m crossing a footbridge (location - https://w3w.co/broom.known.icons) and continuing until you reach a gate (location - https://w3w.co/habit.vibe.busy). Go through the gate to join North Mymms bridleway 2 where you turn left and head N for 50m until you reach a gate on the right (location - https://w3w.co/gaps.round.buyers).

5: Take this path, North Mymms footpath 1, which cuts NE across the field for 310m and drops down to a footbridge across a stream (location - https://w3w.co/rising.habit.limit). Climb the hill on the other side of the bridge, still heading NE, and continue for 160m until you reach a gate leading to a path running along the S edge of Cangsley Grove (location - https://w3w.co/image.grabs.horn). This is North Mymms bridleway 1.

6: Turn right on North Mymms bridleway 1 and follow it NE for 540m, past Cangsley Grove and out into open farmland until you reach a crossing in the tracks (location - https://w3w.co/policy.state.liability).

7: Continue heading NE, still on North Mymms bridleway 1, for 780m until you reach the side of the A1(M) (location - https://w3w.co/backed.rocks.switch).

8: Turn left on North Mymms BOAT 5 (byway open to all traffic) and follow the byway heading N alongside the W side of the A1(M) until you reach Tollgate Road (location - https://w3w.co/fallen.chimp.spits). Turn right. After 180m you will reach a footbridge over the A1(M), (location - https://w3w.co/ears.love.string).
* Here you can take a 360m detour to The Woodman Inn at Water End by crossing the footbridge over the A1(M) and walking down Warrengate Road where you will find the pub on your left (location - https://w3w.co/remedy.echo.pizza). See yellow detour on map above.
9: Immediately after the bridge take the path through the hedgerow on the left and follow the path down to a stile leading into a field (location - https://w3w.co/liked.hatch.food). This is North Mymms footpath 6. Head diagonally to your right following the path back to North Mymms church. If it is muddy or if there is a ‘Bull in field’ sign, you can ignore this path and, instead, go back to the road and follow it back to St Mary’s Church Road.
