I went today (for the first time) to Eretz Haayalim
(www.deer-land. com.il), right at the beginning of the Gush,
They have a new attraction there, called Swing 360.
It was incredibly fun, but for thrill seekers, not the light hearted.
You can see it in action here:

Entrance, with no rides is 15 NIS.
You can choose a Day Pass for 60 NIS, which includes
the Animal Zoo, rope climbing, bunjie, and other attractions,
but NOT the Swing (45 NIS), the large Omega (100 NIS),
or the Paintball.
