Friends of Ewan Williamson, who died after collapsing in extreme heat during a WA bushwalk, have described the Scottish teenager as "one of the kindest and funniest guys you would ever meet".

Police identified the teenager who tragically died after collapsing during a hike near Exmouth as Ewan Williamson on Sunday.

The 14-year-old from Largs in North Ayrshire, Scotland, had only been in WA for a few weeks and was visiting his father.

Friends who were at the Largs Academy school with the teenager took to Facebook to express their shock over the tragedy.

Robert Galloway posted: "He was possibly one of the kindest and funniest guys you would ever meet. Can't imagine what his family are going through. He could of had great life coming for him and now it's all gone. Just now we're all here feeling so sorry for him and I'm sure he really appreciates it up in heaven."

Another mourner Nicole England posted: "R.I.P Euan Williamson! [SIC] This is a tragic accident and my heart goes out to each and every family member of yours, gone but never forgotten".

A spokesman for North Ayrshire Council in Scotland also issued a statement following his death.

"Members of staff at Largs Academy were informed shortly before the school closed on Friday.

"We would like to extend our sympathies to the family and will offer pupils any counselling and support they require when they return to school".

Police confirmed he had been walking with his father, who lives in Geraldton, along the Badjirrajirra Creek in the Cape Range National Park about 20 kilometres south of Exmouth on Friday.

Although the cause of death is yet to be determined it is believed the pair set off with little water and he fell victim to dehydration as temperatures in the region soared above 40 degrees, with few places to find shade.

Police say the boy's father rang triple-0 and the pair were found shortly after, around 700 metres down a gully, and near the car park of the Badjirrajirra Creek walk.

Conditions were hazardous, a police statement said, with "rough terrain and high temperature".

Police carried the boy to the car park and St John Ambulance officers arrived soon after.

He was then taken to Exmouth Hospital, where he died in the early evening.

Police are now preparing a report for the Coroner.
