National Cycle Route 12

The route is on road from Hadley Wood to Dancers Lane, then a bridleway to South Mimms services.

The route passes on road through Old Hatfield and near to Mill Green Museum (watermill), the off-road section then continuing into Welwyn Garden City.

The cycle route then winds through the quiet streets of the Handside part of Welwyn Garden City to reach an off-road path through Sherrardspark Wood up to the Great North Road.

North-west of Welwyn Garden City from Ayot Green, where there is a junction with NCN57, NCN12 follows quiet country lanes but with some very steep hills (northbound) near Codicote.

Route 12 continues, signed, to Sandy and then via St Neots and then via Grafham Water and Brampton to Huntingdon.

Huntingdon | Peterborough | Spalding | Boston | Grimsby North of Huntingdon route 12 (delisted in part by Sustrans) takes a slightly roundabout rural route to Peterborough to avoid the A1(M) before continuing north through the city and then east to Spalding via Crowland, with its remarkable three way medieval Trinity bridge.
