The main road through the Barrington Tops National Park has re-opened after being closed as a result of last week's snowfall in the area.
25 millimetres of snow blanketted a widespread area of the park which saw ice form on sections of the Scone-Gloucester Road making driving hazardous.
Laurence Orel from the National Parks and Wildlife Service says motorists should exercise caution and drive to the road and weather conditions.
"It's re-opened, people can now travel through from Gloucester to Scone," he said.
"However we do remind people that from time to time, particularly if conditions are cold that we can get icy or as we've seen snowy conditions.
"So people should take extra care when they're driving around the Tops over winter especially because of the conditions that can be very dangerous for drivers."
The National Parks and Wildlife Service is warning sightseers to be properly prepared when they venture into the Barrington Tops.
The weather bureau is forecasting isolated snowfall for areas of the Upper Hunter above one thousand metres on Friday morning.
Mr Orel says snow sightseers need to consider a range of issues before heading into the national park.
"So make sure you've got obviously an appropriate vehicle and generally four wheel drives are better than two wheel drives," he said.
"However, plenty of warm clothing, some food because sometimes you may get stuck.
"It's also important to remember that mobile phone coverage is rather limited.
"Make sure that you are prepared before you head out."
