Three bushwalkers have been found safe and well after going missing on a trek in the NSW Central Coast hinterland.
The alarm was raised at a Mangrove Mountain farm in the Dharug National Park on Thursday night.
The trio - two women aged 65 and 72, and a 69-year-old man - had set out at 9am and told family members to expect them home about 4pm, NSW Police say.
A command post was established by emergency services at the property and the Westpac Rescue Helicopter later spotted a small campfire in the bush.
However, powerlines in the area prevented it flying closer.

Police have advised those going on bushwalks to wear appropriate clothing, pack adequate food and water, and carry safety equipment.
