In the agency’s own words

Click See More at the bottom of this overview and review the "Need to Know" section of the campground. At Maple Springs, visitors can enjoy the serenity of the campground and surrounding backcountry trails, or spend their days exploring Mammoth Cave. Campers can explore up to ten miles of the cave through a variety of tours available at the Visitor Center. With more than 400 miles (644 km) of mapped passageways, Mammoth Cave ranks as the world's longest known cave system. Mammoth Cave is named for its grand size and scale. Visit the Rotunda for an idea of just how large this underground world is. The World Heritage Site was explored by Native Americans more than 2,000 years ago, and Europeans discovered its existence at the turn of the 19th century. Keep reading

Recreation

Taking the ferry is the quickest route to the campground. If the ferry is unavailable, you will need to drive around, which takes about 45 minutes. For information on ferry schedules and trailer standards, call (270) 758-2166. These sites offer electric and water hookups. Sites 1, 2, 3, and 4 are recommended for equestrian use and feature a horse tie-up area. Please consider sites 5, 6, and 7 before booking the others, and prioritize those with horses for the equestrian sites. Note that there is no sewer or dump station at Maple Springs. A small amphitheater is available on-site, and a large fire pit is provided for groups on a first-come, first-served basis.

This remote campsite is quiet, peaceful and ideal for those who want to be immersed in nature. Wildlife includes deer, turkey, and coyotes.

Who keeps the booking fee

The agency’s own policy text says the reservation fee and the cancellation processing fee are “retained by the reservation service contractor”, and that a campground concessionaire will decline to refund them because “they did not receive these fees”. Recreation.gov is run under contract by Booz Allen Hamilton. What share of your booking fee the contractor keeps isn’t published in any federal dataset we can read, so we print no number for it.

Two offices, two different asks. The draft to the agency asks it to set aside a published share of the sites here for whoever drives up. The draft to Congress asks why that share is zero and presses for a published minimum at the campgrounds it funds.

Read the draft, or change the wording

For the camper who turned up, or tried to book, and couldn’t get in. Every draft is written from this campground’s own record (its agency, its unit, its site count and its own weekend) and the buttons above copy whichever wording is selected here.

To Mammoth Cave National Park

Asks the National Park Service to set aside a published share of the sites here for whoever drives up, and to post what that share is.

Subject Hold back a share of sites at Maple Springs for campers who drive up

To the National Park Service, Mammoth Cave National Park:

I tried to camp at Maple Springs in Kentucky and couldn’t.

All 7 sites at Maple Springs are reservable, and the agency's own record lists none held back for somebody who drives up. On Saturday, October 17, all 7 sites recreation.gov was offering there were already booked.

1,623 of the 7,647 federal campgrounds in this country still keep at least some sites for whoever arrives first. Maple Springs keeps none, and that’s a choice somebody made rather than a rule.

I’m asking for one specific thing: set aside a published share of the sites at Maple Springs as first-come, first-served, and post what that share is so it can be checked.

Somebody who drives up has no way in, and no way to find out whether they might have had one.

Asks them to put the question to the agency in writing, and to press for a published minimum share of walk-up sites across the campgrounds they fund.

Dear Brett Guthrie,

I’m a constituent in Kentucky’s 2nd district. I tried to camp at Maple Springs, Mammoth Cave National Park, Kentucky, and couldn’t.

1,623 of the 7,647 federal campgrounds in this country still keep at least some sites for whoever arrives first. Maple Springs keeps none, and that’s a choice somebody made rather than a rule.

I’m not asking you to run Maple Springs. I’m asking you to put it to the National Park Service in writing: why is the share of first-come sites there zero, and what would a published minimum share cost? Please press for that minimum at the federal campgrounds you fund.

The people who open these campgrounds, collect the fees and keep the water running are seasonal positions. At GS-5, base pay plus the government's own 36.25% benefit factor, one costs about $47,414 a year. One percent of the $13.3 billion the USS Gerald R. Ford cost to procure would pay for about 2,800 of them for a year. Both figures are the government's own (a Congressional Research Service report and an OPM pay table), and I’m glad to send them.

every fact on this page, and where it came from
Right now: recreation.gov is offering sites on 30 of the next 30 nights, which isn’t something a closed campground does.
Cell signal: the Park Service’s own campground description, read as text by CAMPANAC. None of this is a measurement. It’s what the land manager published about the place, and phones, carriers and weather all disagree with each other; treat it as a warning, not a promise.
