GATLINBURG, Tenn. -- Federal budget cuts have claimed another visible victim -- six areas in Great Smoky Mountains National Park.

Officials at the federal park said Tuesday that budget cuts will close three campgrounds, two picnic areas, a horse camp and several access roads during the 2013 season. In addition, several park facilities will open later than usual.

It’s another effect of the so-called sequestration cuts which went into effect earlier this month after Democrats and Republicans failed to agree on ways to trim federal spending.

Molly Schroer, a spokeswoman for the Great Smoky Mountains National Park, said the park’s budget was cut 5 percent. That forced officials to limit staffing and hiring for the season.

Facilities that will not open in 2013 are the Look Rock Campground and Picnic Area and the Abrams Creek Campground, both in Tennessee; and the Balsam Mountain Campground and Picnic Area and the Tow String Horse Camp on the North Carolina side of the park. The Balsam Mountain closure also means nearby Heintooga Ridge and Balsam Mountain roads will not be opened this year.

“We regret this will cause inconvenience to park visitors, especially those who have enjoyed these more remote areas of the Smokies year after year,” said park Superintendent Dale Ditmanson. “We have focused our workforce to maximize the use of facilities through the remainder of the park.”

Reservations for campgrounds, horseback riding and picnic areas are available online here or here for some camping areas..
