Alt Text Map of Mammoth Cave National Park in Kentucky. The park area is shown in green, surrounding terrain in ivory white, roads mostly in black, and a few towns in yellow. Extended Description Starting from a narrow strip of land extending northward from Interstate 65, the park boundary expands dramatically into an irregular, amorphous shape with jagged edges that continually widens as it reaches further north. The Green River winds vigorously across the width of the park. Dozens of trails, roads, campgrounds, peaks, and sites are labeled. The Visitor Center is in the belly of the park to the right of center. State Route 1352 drops into the park from the northern edge to reach the visitor center. More state routes extend in a loose X shape out from the visitor center. This description will use those divisions to focus on parcels of land. State Route 1352 becomes Green River Ferry Road inside the park. About halfway between the northern border of the park and the visitor center, Maple Springs Loop curves off State Route 1352 to pass Maple Springs, Maple Springs Group Campground, Maple Springs Trailhead, which has a backcountry parking area, and Big Hollow Trailhead, which leads to Big Hollow Trail North Loop. The visitor center is enclosed within a square with a note reading “See detail map.” Once in that square, State Route 1352 runs south of the Visitor Center, Historic Entrance, and The Lodge at Mammoth Cave, which has a campground, before ending at a four-way intersection with Mammoth Cave Parkway and a small no-outlet road going just outside the square. Green River Ferry, an operating ferry, which has a boat launch, canoe launch, and backcountry parking area, is at the intersection of State Route 1352 and the Green River. State Route 474, which becomes Flint Ridge Road inside the park, travels from near the right edge of the map and enters the park along its eastern border. Dennison Ferry Road and the gravel Crystal Cave Road, a gated road, leading to Crystal Cave both branch north off State Route 474 near the entrance. Across the river from the White Oak campsite is Dennison Ferry Day Use Area (no ferry, no potable water), which has a picnic area, backcountry parking area, and canoe launch. Flint Ridge Road passes Mammoth Cave Baptist Church; the gravel Great Onyx Cave Road, a gated road, which leads north to Great Onyx Cave; and Eaton Valley before entering the square indicating the boundaries of the detail map. Sites between State Routes 1352 and Flint Ridge Road in the upper right lobe of the park include Ugly Creek Road, which has a note in red text reading “Warning: Do not cross when water covers the ford”; Big Woods; White Oak with a backcountry parking area; the White Oak Trail, which leads to the White Oak backcountry campsite in the bend of the Green River near Three Sisters Island; and Lucky Island in the river along the northeast of the park. Now starting near the visitor center, Mammoth Cave Parkway connects State Route 474 with 1352 before curling south and then southeast out of the park. The Mammoth Cave Railroad Bike & Hike Trail travels alongside the parkway to the southeast edge of the park, before continuing along the thin, green corridor leading south along Park City Road to a backcountry parking area near Interstate 65 and Park City. Mammoth Cave Parkway also passes Sloans Crossing Pond Walk, which has wheelchair access, a picnic area, and a backcountry parking area; the gravel Union City Road, which is gated; and an additional backcountry parking area just past the Union City Road gate. Just northeast of Mammoth Cave Parkway is Cave City Road, which travels at mostly parallel to the parkway. Starting at the eastern park boundary, Cave City Road runs across Mammoth Cave Ridge and passes the Sand Cave Trail, which has wheelchair access and a backcountry parking area and leads to Sand Cave; Park Ridge Road, which largely follows the park boundary and connects to Flint Ridge Road at its northern end; and an elevator. About halfway up its length, another road branches off of Cave City Road to the south to reach New Entrance and Frozen Niagara Entrance. Finally Cave City Road terminates at Mammoth Cave Parkway, and another road extending past this intersection curls in on itself at its terminus near the Violet City Entrance and Carmichael Entrance, which are south of the visitor center. Doyel Valley is between Mammoth Cave Parkway and Cave City Road, and Houchins Valley is the only site between Cave City Road and State Route 474. West of Mammoth Cave Parkway and moving east to west along Brownsville Road to the Green River are Woolsey Valley; Cedar Sink Trail, which has a backcountry parking area; Joppa Ridge and the unpaved Joppa Ridge Road; Brownsville Road; and Turnhole Bend Nature Trail, which has a backcountry parking area, near Turnhole Spring. Sand Cave Island; Turnhole Bend, with a backcountry campsite; and Boardcut Island are within a sharp bend in the river. Now following the river west, Houchin Ferry (ferry not in service), which has a picnic area, canoe launch, and a backcountry parking area; and Houchin Ferry Campground are near the southwestern edge of the park abutting Brownsville, which has a boat launch. The unpaved Houchin Verry Road starts at the ferry and travels north and east past Temple Hill, which has a backcountry parking area, and First Creek, also with backcountry parking, off the northwest side of the park. Houchin Ferry Road continues outside the park to the west as Ollie Ridge Road, which curves back down into the park to end near the Great Onyx Jobs Corps Center; and to the east as Olli Road, which leads to a backcountry parking area at Lincoln just before reaching an intersection with State Route 728 Most of the rest of the western half of the park is dotted with backcountry campsites, trails, and creeks. North of the western point of the park, the Tailwater Recreation Area is shown in brown at the western end of State Route 728 and has the Nolin River Dam, which impounds the large Nolin River Lake; two boat launches; and a picnic area.
