The cache is a small Sistemia container that is suitable for small swaps. If you want any more information around the Geofest please see the following link

I have set up 4 caches out there, roughly North, South East and West of the Geofest GZ. This one has lots of parking but is a bit tricky if going north to get back out on SH1 so please be careful.
Hope you enjoy them.
