The very worthwhile 4.5km Karangahake Gorge Historic Walkway takes 1½ hours (each way) and starts from the car park 14km west of Waihi. It follows the disused railway line and the Ohinemuri River to Waikino station, where you can pick up the vintage train to Waihi, stopping in at Waikino Station Cafe while you wait.
