(CNN) -- From Yellowstone National Park to the Everglades, America's 391 national parks are in need of repair -- and thanks to the economic stimulus signed into law, help is now underway.



President Obama and his family visit the Grand Canyon in Arizona, a national park.



President Obama's $787 billion economic stimulus plan passed in February and designated $750 million dollars to the national parks.



But not all of the stimulus money is being used -- and the parks are facing a $9 billion backlog in maintenance projects. So far, nearly 10 percent is in the pipeline.



"We are picking away at it as much as we can and we've been fortunate to have the recovery act money," said Jeffrey Olson of the National Park Service.



Olson said half of the $9 billion is slated to go for road repairs.



"Half of that [$9 billion] is roads and about $2 billion of that are the most pressing needs -- those we get some help from the stimulus. The president's budget proposal is calling for more maintenance and construction money," Olsen said.



Dan Wenk, the acting director of the National Park Service says most of those pressing needs include, "camp grounds, camp sites, it's amphitheaters for evening programs. It's the bathrooms. It's literally everything we have to make our visits enjoyable."



And those needs, Ranger Rocky Schroeder hopes, will be fulfilled soon.  Watch more on the national parks facelift »



Schroeder patrols Prince William Park, about 35 miles outside the nation's capital. It has more than a dozen historic cabins slated for repair and is just one of the 250 national parks getting a face lift because of the stimulus package.



"The stimulus will help keep our visitors here, keep them happy and keep them coming back," Schroeder added.



And the numbers are good for national parks.



As of the end of July, attendance at the parks is up roughly 3 percent from the same time last year, according to the parks service. In 2008, nearly 275 million people visited the national parks compared to 272 million in 2006.



At Prince William Forest park, officials are hoping to start putting the money to use next month -- and said they've had overwhelming interest. For these stimulus projects, they need to hire six additional people. So far, they've received nearly 200 applications.



The Interior Department estimates the stimulus allocation will create around 8,000 jobs over two years -- though many will be temporary.



"It's stimulus because we are putting people to work ... but it's also stimulus because we're creating a better place ... increasing the visitor experience," Wenk said.



Some Republicans, however, are skeptical.



"Clearly we need to improve our national parks ... but nobody should confuse that with economic stimulus. I mean frankly that's just false advertising," Rep. Jeb Hensarlin, R-Texas, says.



For Ron Tipton of the National Parks Conservation Association, the funding is vital.



"We must ensure our national parks are well funded to address the parks' crumbling historic buildings and trails, enhance the Park Service's ability to protect wildlife, and provide needed public education and services," he said on the association's Web site.



Olson believes that when economic times are tough -- especially during the current recession -- parks are an economically friendly alternative to more expensive getaways.



"We rise above other things like theme parks," he says. "When times are tough economically, people turn inward and ask some really basic questions and there is nothing like being in a national park to ask those questions."



Olson adds that 147 parks in the United States and in the nation's territories have an entry fee, which ranges from $5 to $25; 244 do not have an entry fee.



But when it comes to this money, the key question being asked: How is the stimulus money being used?
