You can no longer wander over fields and farmland on public footpaths. However, there are restrictions on Portland. This is not a comprehensive list - if you know of any sites that should be added or deleted please let me know. These are in an urban location so the Public paths on the reserves are open. The North end of Radipole is closed.
Public footpaths including the coast path are closed.
I do most of my birding in Dorset, England. I am fortunate to live close to the Weymouth RSPB reserves at Radipole and Lodmoor, the Isle of Portland and the Fleet.
