Four people have been rescued after the hot air balloon they were in was forced to make an emergency landing in a wooded area in Gatineau Park.

Police say the balloon landed near Lac Foin, a swampy body of water within the park's limits around 7 p.m. Sunday evening.

MRC des Collines de l'Outaouais police and the National Capital Commission sent all-terrain vehicles to reach the balloon and the four people, which were around a steep embankment.

Cars couldn't reach the landing site.

The four people aboard the balloon were found at 7:30 a.m. ET and they were assessed by paramedics.

A girlfriend of one of the ballooners said the quartet had turned their cellphones off at 3 a.m. to conserve power in case of an emergency.

The balloon, which is owned by the Gatineau Hot Air Balloon Festival, had only eight hours of flying before the crash. It is worth about $65,000.

The pilot told the CBC's Steve Fischer high winds pushed the balloon in another direction, blowing them into Gatineau Park. He said he was forced to make an emergency landing into "soft pine trees" and nobody was injured.

An early search Sunday was called off due to darkness.
