We took our 2 1/2 year old grand daughter to the park. I was surprised that they wanted 5 dollars to park, but the nice attendant pointed us to free parking about 50 yards away (so don't pay unless someone in your group has trouble walking- heck we were there for a "walk-in-the-park" anyway). The mini-train looked fun but was a long wait (would sell out 1-2 trips in advance). Love the setting next to the pool and creek. I've been going to Zilker for 50+ years and I was a bit disappointed that it was a bit dirty and in some disrepair, but it is still a fun, busy place to chase kids around.
