During a visit to the Children’s Museum, adults are invited to explore the exhibits together with their little ones. As a not-for-profit organization that subsidizes each entrance, we count on admission dollars to keep our Museum open.
The Museum does not have free days.
CMOSC does not turn away visitors due to lack of funds. Families are welcome to visit the museum on a pay-what-you-can basis. To participate, tell the front desk staff that you wish to enter under the open door policy.
For safety reasons, adults not accompanied by a child are not allowed in to the Museum unless they have arranged an appointment or tour. Please contact us by phone or email (info@cmosc.org) if you would like a tour.
The Museum is designed for children ages 0 – 10
Yes, we require 1 adult for every 4 children visiting the Museum.
CMOSC offers a variety of self-directed, interactive experiences that encourage exploration, experimentation, and discovery. Let the Science & Imagination Gallery fuel your imagination: produce a box office hit in the puppet theatre or play a 3-star menu in the retro diner. Outside, explore Mary’s Garden, take flight in the winged Ornithopter, find fish in the Russian River, or build waterways in the Sonoma Coastline gravel area.
Yes. Events are listed on the Calendar and on the Events page.
Totopia is a multi-sensory experience designed for infants and toddlers only. This exhibit offers crawlers, early walkers, and toddlers a safe and stimulating environment to explore. If you have older children, we recommend bringing another adult to supervise them in the other areas of the Museum, while you enjoy this space with your wee one.
We encourage all of our visitors to interact and engage with each other and their children. Even if your child is being supervised by other grown-ups, we ask visitors to save their work for another time. Limited space at shared tables also makes laptop use and other similar work an activity best saved for another time and place.
Yes, groups are required to make a reservation ahead of time to receive group rates.
Unregistered groups will be expected to pay full price, and may be turned away at the door due to capacity limits.
Please see the Group Visits page under Visit for more information.
We love to have children visit the Museum on their birthday! For the comfort of all our visitors, the Museum cannot accommodate unscheduled parties at our picnic tables. Please see the Birthday Parties page to book your celebration.
Strollers are allowed in Mary’s Garden only. Stroller parking is available at the entrance to the garden.
There are two healthy snack vending machines in Mary’s Garden.
There are a number of outdoor picnic tables in Mary’s Garden. Food is not allowed in any of our exhibit areas. Please enjoy all food at our picnic tables only.
Picnic tables are for family dining only and are expected to be shared. Staff may ask families to give up their table after 30 minutes of use if there are others waiting to find seating. Tables cannot be reserved or saved, and birthday parties in the picnic area are not permitted.
Open cubbies are available in the lobby on a first-come, first-served basis. Please do not leave valuables in the cubbies.
No; adult supervision is required for all children at all times.

The Museum does not currently have specific nursing areas of the Museum, however we do have a comfy couch in the Family Resource Center (located in the Science & Imagination Gallery), as well as benches and picnic tables in shady areas.
No. For safety reasons, shoes must be worn at all times and in all areas except Totopia.
The water in the Mini Russian River exhibit is not treated with chemicals. Only UV filtration systems are utilized to allow fish and frogs to share the river as it filters into the wetlands area. Putting feet in the river adds germs and pollutants which make the water dirty and unfit for play and creature habitats.
The Loving Ella Foundation generously donated funding to create Ella’s Art studio in memory of Ella Bisbee, a very young artist from Sonoma County.
