The pits to the north of the Reserve continue almost to Buckden. Those closest to the A1 (A1 Pits and Sailing Lake) are used for water sports and can be visited by existing footpaths. The other pits (Washout, Island, Diddington and Pumphouse Pits) currently fall within the working quarry and are strictly private. However, there is limited viewing from public footpaths around Diddington. Park at the public Car Park in Diddington Village. A footpath runs north around the northern edge of the two Pumphouse Pits. Going south from the Car Park there is a path that leads past the current extraction area and conveyors giving views of Diddington Pit before heading through a small wood and back to Little Paxton. There is no short circular walk from Diddington at present.

Much of the New Workings will fall into the Reserve eventually and there will be new footpaths, cycleways and hides when this happens. Please keep to the paths or you will be challenged by staff from the quarry or the Diddington Estate. Please be polite and comply with their requests as the future development of the site for birding and wildlife conservation can only happen through mutual cooperation and respect.
