We decided to go out for a little adventure and we went to explore the Irvine Regional Park. It was a little bit cool and damp so we didn't do a whole lot, but we found the Children's Garden Trail and played there for a while.
We'll go back to this regularly now, it's only $3.00 to park and most of the stuff is free with the exception of the train ride and the zoo I think.
Even though the park seems small, it's pretty big, after we were done walking the trail and playing on the kids playground, I drove around the various winding roads and I felt like I could get lost in there.
Hope you check it out if you can!
