Everett's Campsite, on the Mohaka River in Te Haroto, attracts hundreds of campers every year. It is one of the few free camping spots in Hawke's Bay where dogs are not prohibited.
But in November last year, its access road was closed because it was unsafe after a slip.
"It's unfortunate we've had to close it so far for safety reasons," DOC senior ranger Malcolm Lock said.
"We've been trying to negotiate access via different ways but have been unsuccessful so far."
The road exists thanks to an easement on iwi land leased by local forestry company Pan Pac. Pan Pac say because the underlying soil is easily eroded, any repair might only last weeks. And because the company does not use the road, any permanent repair would not be until the pines are harvested in 12 years time.
