A small uninhabited island a few kilometres west of North Berwick, capped by a working lighthouse built by the Stevenson engineering family. Robert Louis Stevenson knew the island intimately and used it as the model for Treasure Island. Today Fidra is a Scottish Wildlife Trust reserve protecting nesting puffins, eiders, and shags.
You can see Fidra clearly from Yellowcraig beach; boat trips run from North Berwick harbour in summer.
