Take a Walk in the Treetops

We are getting ready to open the Tree Canopy Walkway for the season! The Tree Canopy Walkway will be open on weekends starting Saturday, May 23 (and open daily starting June 23).

Enjoy a treetop adventure on a series of platforms and rope bridges suspended high in the trees where kids and adults explore life in the canopy just as scientists do in the forest, and then zip-line down to the ground.

Summer Exhibit Opening Soon!

Whales compose, bullfrogs chorus, songbirds greet the dawn, and people everywhere sing and dance. What do we all have in common? Find out when our summer exhibit, Wild Music: Experience the Sounds and Songs of Life, opens on Saturday, May 30!

This incredible exhibit is one of the largest traveling exhibits that we have had! It will take up almost two floors, and will take almost two weeks to install. Please pardon our appearance during installation.

Join us at the exhibit's opening day on May 30 and be the first to play in the Jamming Room, discover the songs of the animal kingdom, and explore sounds in the Ocean Deep. Check out the West African Rhythm Project, performing at noon, and then join them in an interactive drum session. Plus, enjoy Soundtastic Science Discovery programs throughout the day!

You Won't Believe Your Eyes

Discover unseen worlds and hidden dimensions beyond our normal vision to uncover the mysteries of things too fast, too slow, too small or simply invisible in the film Mysteries of the Unseen World, now playing in the Alden Digital Planetarium: A National Geographic Theater.

The film, narrated by Forest Whitaker, uses innovative high-speed and time-lapse photography, electron microscopy, and nanotechnology, to transport audiences to an enthralling secret world of nature, events, and breathtaking phenomena not visible to the naked eye.

Mysteries of the Unseen World is now playing daily at 3:00 p.m. Tickets can be purchased at our Tickets and Information Desk on the day of your visit. Tickets: $5 per person (plus museum admission)/$4 EcoTarium members.

Mysteries of the Unseen World is presented locally by Unum.
