Campers have been handed an early Easter gift with the state government dumping camping fees for more than 500 basic camp sites.

The former Napthine government introduced a $13 fee for basic camp sites, as well as increases to fees for other types of camp grounds in national parks, in a bid to boost maintenance.

On Thursday Environment Minister Lisa Neville said the fee for 536 camp sites at 70 camp grounds had been axed. People who have already paid for Easter camping will be entitled to a refund.

The booking system for basic sites, which are unserviced and have either a pit toilet or no toilet, will also be phased out by July 1.

Parks Victoria has also been asked to review the fee structure for other camp grounds to see if it is fair and whether it may adversely affect visitor numbers.
