Taynish National Nature Reserve (Scottish Gaelic: Tèarmann NàdairNàiseanta Taighnis) is situated southwest of the village of Tayvallich in the council area of Argyll and Bute on the west coast of Scotland. The reserve encompasses almost all of the Taynish peninsula, which is around 5 km long and 1 km wide. The woodlands at Taynish are often described as a 'temperate rainforest', benefiting from the mild and moist climate brought about by the Gulf Stream. Taynish is owned and managed by NatureScot and was declared a national nature reserve (NNR) in 1977. The reserve was formerly also a biosphere reserve, but this status was withdrawn in 2014.
