Hayburn Wyke is a National Trust woodland site on the Yorkshire Coast that has been under ownership since 1981. It is a secluded valley with semi-natural woodland with locally frequent mature trees, with a stream, Hayburn Beck, running down to the sea via a series of waterfalls (a wyke is a local term for a small inlet to the sea), with a final large waterfall, falling onto a rocky beach below. The site is important for its woodland and marine habitats and for its geology. A variety of birds can be found in or near the beck including.: pied flycatcher; song thrush; redstart; dipper; grey wagtail; tawny owl; chiffchaff; willow warbler; goldcrest; blue tit and blackcap.
The woodland is deciduous throughout the site apart from further up the Beck, where it is a mix of broadleaved and conifer. The woodland is composed mainly of oak, with ash, sycamore, birch and elm and supports an exceptionally rich ground flora. Look out for Dippers along the stream. Consider the amount of tree cover when looking for this cache.
