Washington state Discover Pass prices are increasing on Wednesday, climbing from $30 to $45 per year. The pass is a fee charged to park vehicles at state-run parks, lands and recreation sites. While minority-party Republicans were staunch opponents of the $15, or 50 percent, price hike, supporters pointed out that the cost hadn’t risen since the pass was implemented in 2011 — despite high inflation. Revenue from the pass is key to help fund the maintenance and operation of parks, said Sarah Fronk, a Washington State Parks spokesperson. Washington State Parks, established in 1913, predates the national parks system.
