The Crystal Cave, in the museum's words

“Crystal Cave: Slow down and explore a calming sensory environment designed to help children feel grounded and relaxed.”

“If you need special assistance in order to visit or attend or access a program, please contact the Museum ten days in advance to make arrangements.”

  • The Crystal Cave is part of the DreamLab exhibit, not a separate quiet room, so other kids may be in it too.
  • Free second Saturdays may be the busiest days to visit.
