Three children and their families escaped a blaze which took hold at Woodlands Holiday Park on Saturday evening and destroyed two mobile homes.
Staff at the park acted quickly when the alarm was raised in a caravan occupied by a woman and her two children, believed to be between 10 and 14 years of age.
The mobile homes in the immediate area were evacuated, including a couple with an infant from the neighbouring caravan.
The wind fanned the flames toward their property which also caught fire, and both have now been written off.
Four fire appliances from Mundesley, North Walsham, Cromer and Sheringham were dispatched shortly before 8.30pm -arriving within five or six minutes - and spent almost four hours tackling the blaze.
They used eight breathing apparatus and hose reel jets to combat the flames, with water pumped from a nearby swimming pool.
The two caravans were in the Burn Mountain area of the site, and a third has been damaged.
Andrew Hird, general manager of Woodlands Holiday Park, said evacuation procedures were put in place early on because of the flammable gas cylinders nearby.
'Clearly the 49kg gas bottles are everywhere on caravans so we took the action to evacuate the area immediately around it, then evacuated the area of our own hire fleet immediately adjacent,' he said. 'Fire officers arrived within five or six minutes, which was amazing. 'We quickly determined they needed more water, so we rigged them up with our swimming pool. The wind was blowing in a direction which fanned the flames on to another van - so there are two vans completely written off, and a third damaged. 'We obviously feel very sorry for the owners, and have massive praise for the fire service who attended very quickly. The property will now have to be looked at by insurance assessors. 'The most important thing for us is people, not property. The park is open and trading as normal and the only part that is not open is the swimming pool, which does not have enough water.'
Fire crews left the scene at around 12.20am on Sunday morning, but investigators returned that day to carry out assessments.
