Exclusive: local trust that backs proposal says there is urgent need to tackle impact of greater tourism

Scotland’s heritage agency plans to introduce an admission fee at the neolithic Calanais standing stones, one of the most popular and revered cultural sites in the Hebrides.

The fee proposal coincides with a £6m revamp of Calanais visitor facilities being built in response to a surge in tourism to the Western Isles, driven largely by day trips by cruise ship passengers.
