They have a website and a quick Google search can tell you that. However, you may be able to snag free passes at any of the libraries, if they haven't already been claimed. The library passes are good for four admissions, and children 2 & under get in for free.
I use groupon..
Otherwise 12 bucks
Children* (Age 3 - 15)$8.00 Adults (Age 16 - 59)$12.00 Senior Citizen (Age 60+)$10.00 Military Personnel (With ID)$7.00 Annual passes start at $50 and are totally worth it in my opinion.
