Port Campbell Sergeant David Banks said he was concerned people flouted the rules at attractions such as the Twelve Apostles - often to get a shot for social media.

It comes after a woman fell to her death at the Grampians on the weekend.

"No photograph is worth your life," Sergeant Banks said.

"It's a big concern because the barriers have been put up for a reason."

Sergeant Banks said the cliffs could crumble or people could slip on gravel.

He said police had regular discussions with Parks Victoria about the issues surrounding people breaking the rules.

"It's ridiculous," Sergeant Banks said.

He said people ignoring the warning signs were not only putting themselves at risk - they were also compromising the safety of others who tried to help them.

Sergeant Banks said it was a difficult issue to police.

Parks Victoria's area chief ranger Michael Smith said the authority was terribly saddened by the tragic death at the Grampians.

"With warm weather and holidays approaching, people should plan ahead and be prepared when heading out into nature," Mr Smith said.

"In all of the state's parks and reserves, make sure you observe signage and stay behind fences and barriers, which are in place to keep people and the environment safe."

"Along Victoria's fragile coastline, people should take special care to stay behind barriers and not approach cliff edges."

In the event of an emergency in a park, visitors should call Triple Zero or 112 to access police and emergency services.

Many parks feature emergency markers, which are special green signs with a unique code on them so emergency responders can pinpoint exact locations.

Mr Smith said people should be aware, however, that many areas in parks are outside mobile range.
