Trail guide
Old Coach Road is an easy 1.1 km (0.7 mile) loop from Greyneys Shelter, taking about 30 minutes. It follows a surviving section of the old coach route through forest, then returns to the same picnic area on a newer track. It is a good short stop for a little history and stream scenery rather than a long hike or a big viewpoint. Small loop choices at the northern end change the track slightly; a full GPS trace can read closer to 1.25 km, so treat 1.1 km as the standard figure rather than an exact measurement.
The old road sits on a bench cut into the slope above the Bealey River floodplain. Coaches used this higher line to avoid the flood-prone riverbed, and short sections of rock walling remain. Look at the width and shape of the bench as you walk: the engineering is the main attraction. This is a fragment of the old Christchurch-to-Greymouth coach route, not a long route between those towns.
Small cascades cross the path, and short timber bridges span streams. Near the northern end, a rope handrail offers a chance to slow down and notice the forest by touch. The circuit returns on a newer path, with an open stretch near SH73 where traffic is audible. Watch for damp or uneven footing around the streams.
Park at the Greyneys Shelter picnic area on SH73; the walk starts at the eastern end and returns to the same access. Bring your own food and water; none is documented on the walk. Arthur's Pass weather can change quickly, so carry a warm layer and rain protection. Dogs are not allowed on this track.
