Before You Visit


MMGM is ADA compliant, and all galleries are accessible to wheelchairs. Complimentary rollator, wheelchair, and stroller are available on a first come first served basis. ADA compliant parking and ground-level entrance is found in the parking lot off Chapman Street directly adjoining the museum. Some of MMGM’s galleries have loud noises, moving video and flashing lights that come on periodically throughout the day. The admission staff will inform all visitors of the timing of the flashing lights in the Space Rocks Gallery, and headphones are available at the admissions desk upon request. Service animals are welcome.

What to Expect

Large strollers and large backpacks are encouraged to be parked in the coat check area of the Discovery Gallery.

Photography is welcome for noncommercial use. Please no tripods. Visitors may be photographed unless otherwise requested.
MMGM’s galleries flow in a single direction to ensure you see everything. In other words, keep walking in one direction so you don’t miss a thing!
