An adult and six children are being guided out of a walking track after they spent the night stranded in a southeast Queensland national park.

The hikers called emergency services on Thursday night from Mt Barney National Park in the scenic rim.

Emergency services could not guide the group to safety overnight.

Queensland Ambulance Service said the hikers were being guided out and paramedics were assessing the children on Friday morning.

One child required treatment for heat exhaustion.

There are four maintained walking tracks around the base of Mt Barney, according to the Queensland Department of Environment, Science and Innovation.

All four are rated grade four and recommended for experienced bushwalkers.

There are a number of routes to Mt Barney’s summit, which require rock scrambling and climbing skills.
