POPULAR free camping spot Pancake Creek has been blocked to campervans and 4WD vehicles - with signs hung across closed gates proclaiming 'gunfire occurs frequently'.
The private land owner near Agnes Water south of Gladstone, who we could not identify, has also hung do not trespass signs warning those in breach they could be prosecuted.
Astrid Allison and her partner tried to visit the area, which is one of their favourite beaches, on the weekend but their trip was cut short.
"It's the ideal place for fishing, camping and driving along the beach. It was not pleasant to get there, you really do need a four wheel drive," she said.
Ms Allison shared her photos on Facebook, and the post was flooded with comments from other disappointed 4WDers and campers.
One commenter said the land owner was sick of rubbish left behind on his property.
"When we were talking to the property owner he was explaining the amount of rubbish and ripping up of the tracks is out of control -- he had enough.
"Plus Rodds Peninsula is via boat access only if u read the national parks camping info. It was just a bonus that you could get though by car when u could but now its just been flogged out," he wrote on a Facebook page.
Another person wrote: "It's private property and the owner has every right to refuse access unless it's a gazetted road. It's a shame that there isn't 4WD access."

Ms Allison had visited the area twice before, and was keen for her third time.
Now the only way to access the stretch of the beach is by boat.
She said the decision would leave other creeks, like Eurimbula and Little Creek, more busy.
"We went to the other two creeks and they were absolutely packed. We hadn't seen all of Pancake Creek and we were looking forward to it," she said.
"It's such a shame because it was a really beautiful spot for fishing and the beach really did surprise me, how nice it was."
Residents can still access Little Creek and Eurimbula via Agnes Water.
The roads to the two beaches in the National Park area have recently been upgraded.
Deepwater National Park officials did not reply to our calls for comment.
