Tips for Visiting


There is one museum building and an outdoor nature playscape on our campus; the Discovery Museum and Discovery Woods are both accessible and are for all ages. The Discovery Museum combines the best exhibits—beautifully reimagined and redesigned using Universal Design principles—from the former Science Discovery Museum and Children's Discovery Museum into one building. There are also a number of outdoor exhibits spread throughout our 4.5 acre campus, and a trailhead to 180 acres of Great Hill conservation land. And, of course, Bessie the dinosaur graces our front lawn.


We offer more than 400 staff-led programs per year, free with admission or membership. Most of these programs have drop-in hours—come when you can! Check our calendar to see what’s scheduled on the day of your planned visit.

If you come for an outdoor program—they often take place no matter the weather—please be sure to dress your child (and yourself!) for the time outside. Coats, hats, gloves, and proper footwear can make an outdoor experience even more enjoyable for your little one.


Children should be adequately supervised by responsible adults at all times.

Discovery Woods is an outdoor museum exhibit about nature play and choosing to take “just right” risks.

Adult supervision by you helps kids make choices that are right for their age and ability.  It is ok for kids to decide that an activity might be for “next time” they come.

How Long Does a Visit Take?

Good question—it really depends on the age and interests of your child! First-time visitors who visit all of our facilities spend up to three hours learning, playing, and exploring. You are welcome to leave the buildings to picnic on our campus or go out to lunch, and re-enter later in the day.

Change of Clothes?

There are waterproof smocks available in our Water Gallery. But, exploration of the properties of water can sometimes result in some wet clothing. You might consider bringing a change of clothes for your young scientist, or visiting the Water Gallery at the end of your visit rather than at the beginning.

If your child uses a hearing device such as hearing aids or a cochlear implant, you may want to bring a water-resistant cover for them.


Out of respect for people with allergies, no food or drinks are permitted on the exhibit floors or in Discovery Woods. Snacks can be eaten while seated on the benches in our lobby, and there are a number of picnic tables on our patio and throughout the grounds. Feel free to picnic outside and re-enter the buildings when ready.

In our gift shop there is a vending machine of healthy snacks and drinks, and we are happy to recommend nearby family-friendly eateries; please ask for a map with locations at the Admission desk.


Strollers are permitted in the Discovery Museum, however we recommend a Snugglie or backpack carrier for your visit to this building; these are available to borrow at the Admissions desk.  If a stroller is necessary, an umbrella stroller works best.

Stroller parking is available outside the building or in the lobby.


There are five restrooms in the building: a family restroom, boys restroom, and girls restroom on the first floor; boys and girls restrooms on the second floor. All restrooms are handicap accessible and include changing tables.

Changing Areas

All five restrooms in the building include changing tables.

Infant Feeding/Nursing

A private Care and Feeding Corner is located in the Brain Building Together exhibiton the second floor. It is equipped with a dimmable light, glider chair, and outlet. A bottle warmer and sink are available nearby.

No Smoking

Smoking of any kind, including tobacco, marijuana, vaping, juuling, or any other e-cigarette, is prohibited throughout the entire campus, including Discovery Woods.


During your visit you may be photographed and/or videotaped by our staff for marketing purposes. If you prefer not to be, please tell us at the Admissions desk. We will happily provide stickers to your party so that we know to avoid you with our cameras.


The museum has free parking. We are currently in the process of adding more parking to our campus, but in the meantime please note that our busiest times are 10am to noon.

Please observe the fire lane signs and park only in designated spaces to keep the lot safe for pedestrians, buses, and emergency vehicle access. Use your creativity inside the museum, not in the parking lots!

Handicap spots are available near the rear of the building.

The town of Acton offers its MinuteVan service on weekdays. Call 978-844-6809 to make a reservation, or book your trip on their website. Trips must be booked 24 hours in advance. MinuteVan services are separate and independent from the Discovery Museum.

Let It Snow!

New England weather can be unpredictable! There may be snow or ice on the Discovery Woods path, so please wear appropriate footwear and walk carefully. And please, dress your children for the weather--they may want to play outside longer than you anticipate!


We welcome visitors of all ability and mobility levels and will work with you or your group to accommodate any special needs. Please call 978-264-4200 x111 with any questions.

Discovery Museum and our Discovery Woods nature playscape and Treehouse are all wheelchair accessible. Service dogs are welcome.

Our Especially for Me programs offer free admission hours and special events for families with members with an autism spectrum disorder, with vision loss, and who are deaf or hard of hearing. 

The Discovery Museum has three floors; each is accessible by elevator. There are two elevators in the building and an accessible entrance. Exhibits are accessible and were designed based on Universal Design principles to be useable and appealing to the widest range of people. 

Discovery Woods is inclusive and accessible. An accessible pathway winds through the space, and the Discovery Treehouse is accessed on-grade from the driveway.

Resources available to prepare for your visit include Story Guides (social stories) to the Museum and Discovery Woods, as well a Sensory Guide. These are available both online and at our Admissions Desk. You might also visit the Exhibits section of our website. Please note that Discovery Woods is open year-round, but closes at dusk and will not be open for evening events during the winter months.

Noise reducing headphones are available to visitors who may be sensitive to sound or need a break from stimulation. A portable step stool is available to borrow for easier access to exhibits. Please ask at the Admissions Desk for these items.

If your child uses a hearing device such as hearing aids or a cochlear implant, you may want to bring a water-resistant cover for them for your time spent in our Water Gallery. 

Looking for a quiet spot? A staff member will be happy to point you in the right direction or find a good spot for you and your child.

Adults Matter

We ask that all children under the age of 14 be accompanied by an adult at all times. Children are not permitted to enter or leave the buildings or Discovery Woods without an adult.

Unaccompanied Adults

We ask that any adults who wish to visit the museum without a child leave a photo ID at our Admissions desk.

Museum Cleaning Policies

Our floor staff cleans surfaces and exhibit components throughout the day.

“Tasted Toy" bins are provided in Bessie's House and Brain Building Together for any toys that are accidentally mouthed. All toys are disinfected before being put back out on the floor.

A professional cleaning service provides deep cleaning at night.

There are hand sanitizing stations in the building.

Need Help?

Just ask! Our Explorer staff members are here to support your museum experience. They can be identified by their name tags and the purple aprons worn in the museum and purple aprons or blue jackets worn in Discovery Woods.
