This short walk is easily dismissed, yet it offers a variety in a small package: 45 mins return via the same track, 2.0km, easy, starting at Mokihinui-Seddonville Road inland from Mokihinui.

The walk follows the line the Westport-Seddonville Railway which has since been dismantled (the railhead is now at Ngakawau), starting at a small rise where the line once crossed the road.

From here it continues through a deep cutting squeezed between the road and river, affording nice views of Warrigal Island.

A variety of orchids grow along the track, and a rich tapestry of mosses coat the side of the cutting. The track soon passes through a tunnel (glowworms at night) then over the deep sculpted limestone and tannin-stained waters of Chasm Creek on an old railway bridge.

Beyond here, another small bridge and some regenerating scrub bring you back to the road just short of the Seddonville Hotel.
