If you park in the National Trust car park (see map below) near the Dovecote (sign posted off Bedford Road), there are three buildings of historical interest dating from the 16th century. The Dovecote dates from 1543, the stables from 1539 and the church of St Lawrence.
From there you can walk either via the river path or the old railway path towards Danish Camp Visitor Centre, on towards Willington Lock and then re-join the old railway route on to Blunham
A display board near the car park shows places of interest and a useful map showing a variety of paths and routes to explore the area.
The path along the old railway is well made and forms part of National Cycle Route 51. The are plentiful sign posts and you are never far the National Trust Car Park unless you venture on, past Willington Lock towards Blunham.
