Shetland Islands, Scotland rewards hikers with a raw meeting of sea, sky, and old Norse ground. Walk out to St Ninian’s Isle from Bigton, climb Ward Hill on Fair Isle, or follow the bird-haunted headlands of Hermaness on Unst. Around Mousa, Noss, and the long coastal reaches of Yell and South Mainland, every trail feels exposed, storied, and unmistakably northern.
