Nukuhou saltmarsh is a low-lying area located where the Nukuhou River enters Ohiwa Harbour. The tidal flow from Ohiwa Harbour brings in the salty water, going some way upstream at high tide, and forming a marshy area with a special flora and fauna. The saltmarsh is located adjacent to Wainui Road, between Ohope and Ohiwa, at Cheddar Valley. A lookout and a walkway alongside the road has been formed and is maintained by the Nukuhou Saltmarsh Care Group. Extensive predator control, mainly of rats and stoats, is also performed by the group, to allow other species to survive or flourish.
There is a small parking area by the junction of Wainui Road and Burke Road, providing easy access to the boardwalk leading to the lookout. The track directly off Wainui Road to the lookout is wheelchair-friendly, but the remainder of the walking tracks are not. There are no toilets near the track.
Onekawa Te Mawhai Regional Park is a 26.8 hectare reserve on the headland east of the entrance to Ohiwa Harbour, between Ohiwa and Bryans Beach. The park was opened in 2010, and is managed collaboratively by Bay of Plenty Regional Council, Opotiki District Council, and Upokorehe. There are two pa sites in the park, Onekawa and Te Mawhai, at an elevation of about 100 metres, and walkways across the ridgeline between Ohiwa Harbour and Bryans Beach. Information about the park can be found on the Bay of Plenty Regional Council web site.
The walks can be done as a loop using the beach for one leg, or it can be done as in this case as a figure-8 crossing over the ridgeline twice, and accessing the beaches at either end. Parking is available off Ohiwa Harbour Road, and off Bryans Road, with toilets by the beach at Ohiwa. This walk was done starting and ending at Bryans Road.
