Children can get medals for taking part in the Toyota Kiwi Guardians programme.
Children have five geocaches to look for and a Gordon Park adventure on offer for Conservation Week this year.
The week is September 10-18.
They can go online to the Conservation Department website to start either of the challenges. At the website they can download an adventure map for Gordon
Park Scenic Reserve on the outskirts of Whanganui East, find the code word there and ask for a Toyota Kiwi Guardians medal.
At the same website are instructions for getting involved in geocaching. A free app can be downloaded, and the caches of hidden objects are found using GPS.
There are five in the region - one at the Atene viewpoint, one on the Atene Skyline Track, one at Gordon Park, one at John Coull Hut and one on the Mangapurua Track.
