Follow the riverbed / old 4WD track down the Dobson valley floor from Kennedy Hut. Grough Hut (a 2 bunk bivvy) is just visible from the river, sitting in beech at the top of an alluvial fan on the true right, as shown on topomaps. This section of the Dobson was low when I walked it, but can clearly flood. It can be walked entirely on the true right. 1.5-2.5hrs

Note: Described in the reverse direction to your journey

From Grough Hut, drop back to the riverbed and follow the old 4WD track / riverbed upstream. Kennedy Memorial Hut is on a low terrace on the western bank against a patch of beech forest. This section of the Dobson was low when I walked it, but can clearly flood. It can be walked entirely on the true right. 1.5-2.5hrs
