The Pourakino picnic area is only about 10km from Otautau. You have to leave your car at the main entrance and walk into the area because there are such deep ruts in the road that driving would be unwise. But it is a very short and pleasant walk and hints at the wonderful, native forest within.
There is the old steam engine there of course and blocks where the saw mill once stood. For walkers, there are two trails to choose from. Both trails are loops so there is no chance of getting lost. The trail pictured starts with a wooden bridge built by DoC and proceeds along a waterway with occasional signs to point out features.
In the centre of this photo you can barely see the arched concrete bridge that covers Granite Stream. This bridge was used for carting out logs with bush tractors and locomotives.
The trail takes approximately 45 minutes to walk and is a very lovely, quiet experience.
