Follow Sections 1 to 10 from the Station then
37 Take the second left turn off Newton road into Selbourne Avenue. Continue under the railway arch. This line connected Oxford to Bletchley and thence to Cambridge. It is currently disused apart from occasional freight. After 50 yards, turn left on to a footpath alongside a hedge and ditch After a right and then left dog leg, the remains of a clay pit previously utilised by Bletchley Brickworks can be seen to the right on the other side of the brook. The pit is now being filled. As a consequence part of it is now a hill with vents burning off surplus gas and at times producing noxious fumes. The tall chimneys of the brickworks, (actually in Newton Longeville) have now been demolished but dominated the town for over 50 years just as their fumes dominated the whole of Milton Keynes. The brickworks was one of a series on a belt of clay stretching from Oxfordshire to Cambridgeshire. This was exploited by the London Brick Company when it became known that the carbonaceous material in the clay, previously thought a defect, in fact assisted firing the brick and saved some of the costs involved. Continue for about half a mile alongside the stream.
38 After a stile, turn right and cross the stream at the first Bridge. Turn left to go up some wooden steps and then down wooden steps on the other side of the bank. Turn right to walk alongside the abandoned Brick Pit known as the Blue Lagoon dimly seen through the bushes. After a hundred yards or so look for a convenient, if muddy path down the bank along the south of the 'lagoon'. You will eventually come to one of the gravel paths leading up the slope to your right.

39These
paths lead over a series of one or more wooden walkways to the Blue Lagoon
Park and Nature Reserve. At the next junction turn right to go around the
small lake. After circling the lake you will come to a picnic area at the
North end of the Car Park. To walk into open country follow the road back
south from the car park until it passes under the main railway line to
the Lakes Estate. Before the arch follow the footpath on the right parallel
with the railway. To return to Bletchley branch right off the path around
the lake along a gravel path to the north also parallel with the railway.
to follow the main track left back towards Bletchley.
40 At the
end of the path, turn left along the track but, instead of turning towards
the 'lagoon' again, fork right keeping parallel with railway along a grassy
track. At the end, turn right over a stile and follow the track alongside
the small lake known as 'Newfoundout'. This originally supplied much of
the water for steam locomotives at Bletchley Station. 
Turn
left along Water Eaton Road. This will take you back to Buckingham Road,
which you may cross to return to the Station or turn right towards the
town centre. For a slightly more pleasant diversion, turn left into the
commercial cul de sac just after joining Water Eaton Road and walk across
the park at the end of Wellington Place.
