Discovery Booths are included with general daily admission, which is free for members and ages 15 and younger and $20-$25 for non-members ages 16 and older. Every Saturday through October 17, 2026. Tickets must be reserved in advance of your visit. Be sure to check the activity board in the Visitor Center, for the exact location.
