Scottish actor Kevin McKidd is trekking up Britain's highest mountain, Ben Nevis, to raise money for charity.

The Grey's Anatomy star has swapped the Hollywood Hills for the Scottish Highlands to take on the hiking challenge with his friend and fellow Scottish actor Iain Robertson to raise money for a sudden infant death syndrome charity.

MCKidd, who has two children, wanted to help his pal raise funds for the Scottish Cot Death Trust (Scdt) because Robertson's sister died when she was a tiny baby.

He says, "I know that Iain has personal reasons for supporting such a worthy charity and I'm glad space in my schedule has allowed me to get involved.

"As a parent I can't even begin to imagine what the loss of a child would feel like, I hope people dig deep to help the Scdt continue to offer much-needed support and assistance. It's great to be home and taking in the Scottish scenery again, and helping out such a good cause in the process."
