The cost of getting into about 100 national parks increases on Thursday.
The rates will go up despite the fact that visitation at parks is up, which means bigger crowds, congested traffic and busier visitors' centers. But more people aren't translating into a big boost for park budgets. For example, visitation at Rocky Mountain National Park in Colorado is up 20 percent so far this year and Yosemite, Yellowstone and Zion are also seeing double digit increases. The parks are also seeing the strain.
Kyle Patterson, spokeswoman for Rocky Mountain National Park, says the last hike was in 2009.
"When you're a park that's been around for 100 years, you have an old infrastructure, and for us that's paved roads, unpaved roads, trails system," she says.
But the extra money from increased entrance fees will be a drop in the bucket. Overall, for example, Rocky Mountain National Park estimates it has nearly $70 million in maintenance needs. Across the country's national parks there's an estimated $11.5 billion needed to cover upkeep.
"That's rundown visitor's centers, that is unmaintained trails and crumbling roads," says Emily Douce with the National Parks Conservation Association.
Next year marks the 100 year anniversary of the National Park Service. That means welcoming even bigger crowds, and Douce hopes a bill recently introduced in Congress will help ease the financial strain.
"Unfortunately, over the last several years, Congress has not put the money towards getting these parks ready for the next century of service to the American people," Douce says.
President Barack Obama voiced support for the bill. A key aspect of it would match public and private dollars, an idea first floated under the George W. Bush administration. An era of tight budgets and gridlock in Congress makes the bill a hard sell. Proponents like Douce hope that the anniversary will galvanize support.
The bill would also raise the rate for a senior citizen pass — which is currently $10 for a lifetime pass — as a way to boost national park funding by an estimated $1.5 billion.
"It's so cheap for senior citizens," says Jim Cooney, who recently used his pass to get into Rocky Mountain National Park. "I think they ought to charge us more."
