The rough track to the William Wright Falls starts just past the north end of Orokawa Bay and heads inland up the Orokawa Stream. It can be overgrown, making the path indistinct.
But in any event, the path follows the stream and orange markers are at key points. After about 30 minutes, the path deviates to a side stream to the south, and the Falls are just a couple of minutes away.
