Site Description: Twin Arches is an unusual double sandstone stone arch formed by erosion along a narrow ridge. A designated State Natural Area owned by the NPS, the site's two arches (North and South) are considered the largest in Big South Fork National River and Recreation Area. This pair of arches forms one of the largest natural bridge complexes in the world.
The short 0.7-mile Twin Arches Trail leading to the arches starts at the trailhead. The trail follows a narrow ridge where the trail splits and forms a loop. Turning left here and descending two sets of stairs will take you to the base of the cliff. Staying to the right, you will travel on the bluffline to the North Arch.
This trail divides again with the left trail crossing the South Arch. The stairway between the arches leads down to the base of the cliff and back across the top of the North Arch, forming a loop.
Wildlife to Watch: The site is a large, mature forest that contains a high density of Neotropical species and individuals. Some common breeding birds are Red-eyed Vireo, Ovenbird, Hooded Warbler, Indigo Bunting, Black-throated Green Warbler, Scarlet Tanager, Worm-eating Warbler, and Pine Warbler.
Swainson's Warblers can be found along steep gorges with thick vegetation, but they are uncommon and not always detected.
Northern Saw-whet Owls can be found in winter with some regularity, but much effort is needed to locate these birds.
