Jethou Bluebells Many thanks to a visitor for sharing her picture of Jethou bluebells taken during a highly prized NTG trip to the island early summer '13. Jethou is a tiny gem of an island within the Bailiwick of Guernsey. NTG has been very lucky to be able to take small groups to Jethou for 2 consecutive Summers. It is described as 'unchanged over hundreds of years' - the rabbits don't run away and the birds don't fly. There's no air pollution. Possibly best described as the Galapagos of the Channel Islands.
