When the Department of Conservation (DOC) first came to Whanganui in 1987, it started running Whanganui Summer Nature Programmes each January; a series of walks and talks relating to the environment that we live in.
Previously the parent department Lands & Survey had run the programme in some of the National Parks, but DOC's wider mandate included the coast and historic features. Consequently, the programme was able to include beach walks and historical buildings. DOC's new advocacy role also meant it was able to incorporate offshore islands such as Kapiti and Mana, as well as places like Zealandia (formerly Karori Wildlife Sanctuary).
We also used to do longer and more difficult heli-hikes and tramps in the Ruahine Range and Whanganui National Park.
Initially, private cars were used, but after some drivers never made it to the starting point and others wanted money to carpool, it was decided to use buses.
This, to my mind, was the way to go as you were able to then keep everyone together, you can talk to them about features as you drive by and being higher up you can see quite a lot that you miss from a car. A lot of our clients prefer to be driven, and bus use is great for the environment rather than using 20 or more vehicles.
