You will be entering the Cains Lane Biodiversity Site either throuh the South-East [from Hatton Road] or South-West [from Cains Lane].
This is a Site of Local Importance for Nature Consevartion, situated just on the edge of Heathrow Airport. It's a sizeable area of scrub with rough grassland and scattered trees. Paths have been cut through the scrub in places to allow access. The site is bounded on three sides by hedges.
The resident finches, tits and thrushes are supplemented in summer by warblers, including chiffchaff, willow warbler and blackcap. In winter, flocks of redwings and fieldfares can be seen feeding on the hawthorn berries.
You will be navigating along the numerous paths up to the Northern corner of the site, where the cache awaits
