Indoor-Outdoor Museum of Science and Nature | Worcester, MA

Open Tuesday - Saturday 10:00 a.m. - 5:00 p.m., Sunday 12:00 - 5:00 p.m. Closed Mondays

The EcoTarium is a unique indoor-outdoor museum in Worcester, MA. Set in an urban oasis, the EcoTarium offers a chance to walk through the treetops, take a thrilling multimedia journey through the galaxy at a digital planetarium, meet wildlife, stroll nature trails, and get hands-on with family-friendly exhibits.

The Explorer Express Train is currently out of service.  We apologize for any inconvenience.

Utility Work is underway, so portions of our trails and paths will be closed during the fall.

Nature Explore is Open!

Our new outdoor exhibit features several play areas, each with its own theme. From the Nature Art Area to the Dirt Digging Area to the Climbing and Crawling Area, and more, there is something for every family to enjoy.

The Nature Explore Outdoor Exhibit is sponsored by Harvard Pilgrim Health Care and UniBank. Nature Explore is a collaborative program of Arbor Day Foundation and Dimensions Educational Research Foundation.

New Exhibit! KEVA: Build it Up!

Opening Saturday, October 4

KEVA: Build it Up! stimulates the imagination. These uniform maple planks provide an easy, non-messy way to explore sculpture and design, form and function.

Build structures simply by stacking the planks. No glue, no connectors, just simple engineering and improvisation. This exhibit turns artists into scientists and scientists into artists. KEVA planks inspire the whole family to enjoy building together. 

KEVA: Build it Up! is sponsored by Gorman Richardson Lewis Architects.

Great Pumpkin Fest

Mark your calendars! Our annual family-fun event returns on Saturday, October 25. More than a thousand pumpkins will be lit up and there will be spooky science, trick-or-treating, a free digital planetarium show, and more!

Tickets are $15 each, $12 for EcoTarium members. Children under 2 are free.

Don't miss Great Pumpkin Fest, sponsored by Commerce Bank!
