Bayanne House was originally at the centre of a small estate created in the late 18th century by the Hoseason family of Yell. Many changes in fortune and ownership have resulted in its present extent of only 4.5 acres on the shores of Basta Voe. This small parcel of relatively rich inbye agricultural land supports an enormous range of local flora and fauna.   The croft is designated as an Environmentally Sensitive Area because of this diversity of wildlife and is managed in an ecologically friendly way. Visitors can walk along the beach and watch for otters, seals and wading birds or stroll around the croft looking for wild flowers.
