The British actor – who divides his time with wife Miranda Kerr and their six-month-old son Flynn between London and the US city – was overwhelmed when he took a flight out of California and caught a glimpse of the landscape.
He said: "My first overriding memory of LA is flying out of the city to New Zealand to do 'Lord of the Rings' and looking out of the window of the plane thinking it looked big and intimidating.
"A bit scary really – just so vast and bustling."
Despite regarding Los Angeles as his work base, Orlando loves going out into the hills on his bicycle.
He said: "I love being close to nature and being outdoors, so I would have to say my favourite part of LA is the hills or the canyons, which are great for mountain biking."
However, the actor also loves to spend time at home with his family and friends.
Asked to describe a perfect day, he told Tatler magazine: "Having family time, good food, good friends, a nice glass of wine, then winding down with a movie at home."To be in with a chance of winning 1000 CDs/DVDs including rare, signed and promotional copies simply ‘like’ our Award Winning facebook page here!
