Birdwatchers will see many waders and sea birds on the inlet and flying over farmland. In and around the forest are numerous other birds including pigeon, welcome swallow, bellbird and tui. Some, such as kingfisher and banded rail, find their food in the inlet, but live in forest or wetland, demonstrating the importance of the remaining natural fringe around the inlet.
Another excellent activity is kayaking, especially for exploring the more secretive tidal arms and channels which flank the inlet, though be wary of the muddy conditions and falling tide.
Westhaven (Te Tai Tapu) Marine Reserve covers 536 hectares of tidal sandflats and channels within Whanganui Inlet, on the western coast of Golden Bay.
Westhaven (Whanganui Inlet) Wildlife Management Reserve stretches over 2112 hectares. It covers all tidal sandflats and channels not included in the marine reserve inside a line from Bar Point to South Head Cone.
To get to Westhaven, follow the road from Collingwood to Farewell Spit, taking the left-hand fork just north of Pakawau.
The wildlife management reserve is about six kilometres on, just beyond the turn off to Kaihoka Lakes. Continue on along Dry Road which leads around the inlet to Mangarakau, following the estuary shoreline most of the way.
The estuary is an enclosed, drowned river valley about 13 km long and between 2-3 km wide. As the tide enters the inlet, it divides into northeast and southwest channels before spilling out onto expansive intertidal sandflats, which dominate the estuary.
Seagrass beds, salt marshes, tidal wetlands, dunes, cliffs, islands, rock platforms and underwater reefs are all found within the marine reserve and are important habitat to a variety of species.
About 30 species of marine fish use the inlet at some stage of their life cycle, and it is an important breeding and nursery area for snapper, flatfish, and kahawai. Many fish enter the estuary to take advantage of the rich food supply found in the seagrass beds and sandflats.
The area has always been important to Maori, both as a food basket and as a place to live. Sacred sites and evidence of previous occupation remain today. The manawhenua iwi are Ngati Rarua, Ngati Tama and Te Atiawa.
In colonial times, the coastal forest around the inlet was clear felled and selectively logged, the flax milled and the land mined for coal and gold. Despite these intrusions, there is little permanent ecological damage and most catchments are covered with regenerating forest.
