From the Tōtaranui camp office, follow the avenue road and then Abel Tasman Coast Track past the Ngarata Homestead north towards Anapai.
At 1.4 km, just past the concrete bridge, turn left at the start of the Gibbs Hill track. The track crosses a ford before a 3 km long uphill section begins which has steep sections. At the ridge and next intersection, turn right to Gibbs Hill.
Allow about 1 hour 30 minutes for the climb to the hill top.
Follow the track down the hill until you get to a track junction. Stick to the right to head down to Whariwharangi Bay. It takes about an hour to get to Whariwharangi Bay from the top of Gibbs Hill.
Follow the Coast Track back to Tōtaranui past Mutton Cove and Anapai Bay. Allow 3 hours to get from Whariwharangi to Tōtaranui.
All tracks to Gibbs Hill from Tōtaranui, Pigeon Saddle or the Coast Track above Wainui Bay are first and foremost fire access routes. For the most part they cross either open country or arid, scruffy, gorse/mānuka regeneration.
Views along the ridgeline are superb. You can see from Nelson round to D’Urville Island, to Farewell Spit (with Mt Taranaki on clear winter days) and Golden Bay.
