SES Wangaratta, CFA crews from Moyhu, Whitfield and Cheshunt, and Wangaratta Fire Rescue Victoria attended Paradise Falls yesterday after a man slipped and dislocated his knee.

It took a group effort to support the man back up the steep and at times narrow 500-metre gravel track.

Ambulance Victoria officers were also involved and had an ambulance waiting for the man at the car park.

An SES spokeswoman said the Wangaratta unit responded at 12.05pm.

"They have assisted a male walker - he has injured his leg and needed help to get out," she said.

It comes after a woman was airlifted to Melbourne after an incident at Beechworth Gorge on Saturday.

Multiple personnel including 25 police officers, SES volunteers, firefighters and paramedics attended.

The SES spokeswoman said numerous volunteers had given their time on a long weekend to help others.

"Our volunteers in the North East of the state have been very busy over the Easter weekend, attending to a lot of people who have got into trouble out in the bush," she said.

"It has been similar to this (incident at Cheshunt) with people injuring themselves or falling.

"People should take care and be mindful of their abilities when out in the bush."

Wangaratta police advised no one had been injured in a roll-over attended by Myrtleford officers.

"(It's) a timely reminder to everyone to take care and assess your driving skills before heading onto the dirt roads," police said.

Some tracks in North East parks were closed to allow for planned burns with hazy conditions persisting throughout the weekend.

Forest Fire Management Victoria Hume Deputy Chief Fire Officer Aaron Kennedy said the weather conditions were optimal for burns.
