Police have named the teenage boy who died of dehydration after hiking south of Exmouth on Friday.

The 14-year-old boy is Ewan Louis Williamson, who was visiting from Largs, North Ayrshire, Scotland.

A police spokeswoman said police would prepare a report for the WA State Coroner.

"The circumstances leading to the boy’s death and how the boy died are yet to be determined and will form part of the Coronial report," she said.

The boy and his father were walking along the Badjirrajirra Trail in the Cape Range National Park, about 1100km north of Perth, when the teenager collapsed from heat exhaustion about 2.15pm.

The boy's father, who lives in Geraldton, called triple-0 from his mobile phone.

A St John Ambulance spokesman said crews had to carry equipment to the scene, about 1km south of a nearby carpark.

He said it was reported to them that the boy was suffering from heat exhaustion and was having difficulty breathing.

Paramedics from Exmouth treated the teenager at the scene and took him to Exmouth Hospital. He died there several hours after he collapsed.
