Cross Bark Bay estuary or follow the all-tide track around its edge and climb steeply to a saddle. Here you lose all sense of the sea below as you journey through stands of Manuka.
Return to the shore at Tonga Quarry, where blocks of granite remain from an old quarrying operation. Tonga Island sits offshore surrounded by marine reserve. A short distance on is Onetahuti Bay. The track then climbs over Tonga Saddle and descends to Awaroa Inlet. Follow the shore for 15 minutes to Awaroa Hut and campsite.
