Celandine Route
This is a 12-mile (19 km) walk through woodland, meadows and parks. It finishes at the Grand Union Canal towpath parallel to the Fray's River anabranch of the Colne.
Connections
A short walk east along the Slough Arm of the Grand Union Canal connects.
The Grand Union Canal towpath connects, linking in Brentford (east south-east), Watford and the Midlands (north), and the Paddington Arm (central London, east).
Water quality
All local sewerage runs to the distant Mogden Sewage Treatment Works discharging its treated waters to the Tideway. This spares the Pinn from the incident nitrogen, bleach (ammonia) and other chemical biohazards which many of its catchment homes and business use and/or discharge.
The Pinn's flow is weak save for after moderate or heavy rain. Worn tyre and motor oil run-off is from some roadside drains at biohazardous levels, particularly below the A40 road which is a trunk route of six lanes at this point (this becomes the M40 motorway to the west) – about 0.62 miles (1 km) of this slopes down to the river.
