Keen of Hamar Nature Reserve

It may look like a barren moonscape, but Keen of Hamar’s bare, stony scree supports a unique collection of plants.

This unusual geological reserve is home to special interest plants that have adapted to survive on the rare serpentine rock found on Unst, Shetland.

Edmondston’s chickweed – which is unique to Britain’s most northerly island – is the star attraction. Several more common plants show peculiar serpentine growth forms.

Keen of Hamar is protected as a Site of Special Scientific Interest and a Special Area of Conservation.

NatureScot owns and manages the reserve.  This Keen of Hamar nature reserve leaflet is a good introduction to the reserve.

Best time to visit

Mid-May to early July, for the wild flowers.


Small car park and easy walking ground.

Getting there

Keen of Hamar lies off the A968, just beyond the village of Baltasound. It is signposted from this road. The reserve is a 200m walk from the car park.

A daily bus service runs between Lerwick and Baltasound. Making the return journey on the same day would only allow for a very rushed visit, however.
