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.

Last Weekend to Run! Jump! Fly!

This thrilling exhibit, Run! Jump! Fly! Adventures in Action™ will only be here until Sunday, September 21.

Jump on a balance board and test your snowboarding skills, pedal the Flycycle, take on the Climbing Canyon and get moving with us this summer!

This exhibit is sponsored locally by UniBank and the Worcester Bravehearts.

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.

Get involved with Great Pumpkin Fest!
October is just around the corner, and we’re gearing up for Great Pumpkin Fest 2014! We’re looking for volunteers who get absolutely giddy over ghosts and ghouls – we can’t make this event happen without excited, costume-wearing, decoration-making, big-dreaming folks!
