After posting the first My Favorite Playground in Jerusalem cache (GCA5HV6), I couldn't not mention this playground as well, which is even bigger.
This time the cache is actually hidden inside the playground, in a relatively hard-to-reach place. I'm hoping it will last despite the ultra-high muggle factor.
Note that finding parking is difficult around here. You're best chance is to park at the Israel Museum (free) or Cinema City (a little closer), which are about 15min walk from GZ.
