The Jackal, the Guineafowl and the Barley
The Challenge
You are travelling with a Jackal, a Guineafowl and a sack of Barley. You come to a river, and there is only a small boat to get you and your travelling companions across. The boat is so small that only you and one other item (jackal, guineafowl or barley) can cross at a time. However, if you leave the guineafowl unattended with the barley, it will eat the barley. Likewise, if the jackal and guineafowl are left unattended, the guineafowl will become a meal for the jackal.
In order to receive the final co-ordinates of the cache, you need to get yourself and all three items safely across the river. Once that is done, the final co-ordinates of the cache will be revealed to you.
The Cache
Park at the main Giba Gorge parking and make your way to the trailhead for the "Baby Steps" trail. (about 800m). Then follow the trail to the Wherigo start point. There is some limited parking available near the trailhead, and you can save yourself this walk if you park there. Please park considerately!
Once at the start point, follow the instructions on your GPS Wherigo player (or your smartphone app) and complete the challenge.
