Parking
Start at the informal dirt clearing off Sandham Road near Dargan, about 3 km from the Darling Causeway and Bells Line of Road junction. The last roughly 2 km are unsealed; this is a clearing, not a developed car park.

Trail guide
Dargans Arch Track is an out-and-back of about 1.5 km return from the informal Sandham Road clearing to a sandstone arch in the bush. Allow about an hour including time at the formation. It’s a worthwhile short detour for a striking rock feature, but the distance hides a steep return and a rough finish. The walk is locally documented, though formal public access hasn’t been confirmed, so check access before setting out. Pets aren’t permitted in NSW national parks.
The walk starts on a broad fire trail through bushland, first gently downhill and then more steeply. The fire trail gives way to a narrow path and open rock; the last couple of hundred metres are uneven and the tread becomes hard to follow. Retrace the same line back to the clearing. The climb out is the hardest part, so take your time rather than treating this as an easy stroll because it’s short.
Dargan Arch is a natural sandstone bridge left after a cave roof collapsed. The main route reaches and crosses the arch; it’s unfenced, with open rock underfoot. A rough scramble down to the underside gives a closer look, and a separate overhang lies a little farther on, but those explorations are beyond the mapped route. Skip the descent if the rock is wet or you’re not comfortable scrambling.
