Farne islands- Northumberland
Skomer- off St Davids Pembrokeshire
theres a couple to be going on with, could mtb on all of them but check for biking authorisation.
I've been to the Farne Islands on many occasions. Usually you can't even land there, never mind ride a bike round them. And if MC thinks Sark might be a bit small then the Farnes aren't really going to do the job.
Not sure about Skomer, but, I guess for the same reason as the Farne islands, (protection of wild bird habitat) cycling is probably prohibited.
