Fees will rise at state campgrounds, boat launching sites and museums July 1.
The California State Parks says it needs to offset a $15 million cut in the money it had been receiving from general taxes.
The fee increases will raise a projected $18 million — with an extra $2 million going to backlogged park maintenance and $1 million for additional employees to collect the higher fees.
The department is adopting a sliding scale to blunt the increase — with significantly higher fees for the most popular campgrounds at the busiest times of the year.
The department announced the increases today because campers can begin next month making camping reservations for July.
