Denise Ann Williams, 62, was last heard from on April 15, 2026, while on a hiking trip in Nova Scotia. A visitor from Australia, she had told family she planned to travel to Chéticamp on the western coast of Cape Breton Island; that communication was her last known contact. She was reported missing to the Inverness County District RCMP on April 28, 2026.

Authorities found her rental Nissan Sentra at the Parks Canada Visitor Centre near the Acadian Trail entrance in Cape Breton Highlands National Park. A multi-agency search followed, involving the RCMP and their Police Dog Services, multiple Ground Search and Rescue teams, the Civil Air Search and Rescue Association, Parks Canada, helicopters and ground patrols. The six-day air and ground search turned up no trace, and the official search was suspended on May 4, 2026, pending new information.

Williams is described as 5 feet 4 inches with greyish-blonde, shoulder-length hair. She was believed to be wearing a dark winter jacket, a powder blue toque with Antarctica on it, an orange and blue scarf, and glasses when she disappeared. Does anyone who visited the park or drove the Acadian Trail area in mid-April 2026 have information that could help locate her?
