Cache Copse (another of our caches) uses the same Car Park at N 51° 16.677, W 000° 53.151, so if you are feeling energetic, you could do both.
There is more information about the Dogmersfield Loop here: http://www.bbc.co.uk/southerncounties/community/walks/dogmersfield_loop.shtml
From the car park set off to the right along the canal.
At N 51° 16.403 W 000° 53.600 you can see a bronze horse in the garden of a house opposite.
Continue to N 51° 16.069, W 000° 54.266 where you will find Sprats Hatch Bridge. There are two dates shown, make a note of the missing digit in each:
Built 1(Z= )92 and Restored 197(A= )
Cross the bridge and follow the path by Sprats Hatch Farm for about 200m to a footpath on the right. Go through the gate stile and follow the footpath to where it joins a track and continue to a sharp left turn. You can see Dogmersfield House to your right. Turn left and continue a short distance to another gate stile. There are two telephone numbers shown on the frame:
0195(X= ) 6020(B= )(C= ) and 01491 6(Y= )44(D= )0
You now have the information to give you the coordinates of the final cache at:
N 51° 1A.BCD, W 000° 5X.XYZ
On your way to the cache, notice the bridges across Tundry Pond.
The loop exists because an eighteenth century landowner, Sir Henry Mildmay, struck an agreement with the canal engineers to go round the edge of his park, in return for demolishing, at his own expense, two properties which were in the way of the loop.
Mildmay was also obliged to build two bridges over Tundry Pond to accommodate the revised line of his drive. The estate you’re in is mentioned in the Domesday Book as Doccemere feld.
The name has come down to us almost unchanged: Dog = docce = water lily; mere = lake; feld (originally just a large open space) = field; so, the field by the water lily lake).
To return to the car park, head North along the towpath. Notice the tank traps in this area and a little further down the towpath you will come to a Pillbox with its gun port covering the canal approaches.
