This cache (along with caches Oakley CW2-CW4a) is on a section of the Bromley Common Circular Walk. You will pass through open fields, woodland, sports grounds and cross the River Ravensbourne. The unmade path can get muddy. Many of the fields are used for horse pasture. The whole area is green belt.
The above coordinates take you to the start of the walk on byway 135. There is a house name plate (ABC) on a gate post - if you cannot read it, the name may be found again about 50 yards down the path. Using this information, the film pot sized cache may be found at
