The Kyle of Sutherland is a narrow channel at the head of the Dornoch Firth to which it is joined. It extends about three miles northwest from Bonar Bridge and is fed by the River Oykel. Carbisdale Castle, a former youth hostel, was built as part of the divorce settlement of the Duchess of Sutherland and the King of Norway lived there during the Second World War. The area offers a wealth of activities including mountain bike trails, fishing, walking and golf. Bonar Bridge, a village in the centre of the Kyle of Sutherland, boasts a café, post office and other local shops. The area has historical sites such as Croick Church as well as dramatic scenery and an abundance of wildlife and birdlife including golden eagles, otters and red deer.
