The Explorer Express Train is currently out of service while we upgrade the train and its tracks.

Discover Wild Music

Whales compose, bullfrogs chorus, songbirds greet the dawn, and people everywhere sing and dance. What do we all have in common? Find out at our summer exhibit, Wild Music: Experience the Sounds and Songs of Life, now open through September 6!

Discover how nature is filled with “musicians” that create distinct musical masterpieces to communicate with and relate to one another. And, explore how human music is inspired by the music of other living creatures – from tiny insects to giant whales. Wild Music offers unique experiences to see, hear and feel sounds!

Soundtastic Saturdays -- every Saturday afternoon at 2:30 p.m.
During this special weekly Science Discovery program, learn about how animals perceive and produce sounds, or explore instruments and other tools humans use to create tones, rhythms and music.

Take a Walk in the Treetops

The Tree Canopy Walkway is open for the season! The Tree Canopy Walkway is open daily through August 16.

Enjoy a treetop adventure on a series of platforms and rope bridges suspended high in the trees where kids (ages 5+) and adults explore life in the canopy just as scientists do in the forest, and then zip-line down to the ground.

Tuesday - Saturday: 10:30 a.m. to 12:30 p.m., 1:00 p.m. to 4:00 p.m.
Sunday: 12:30 p.m. to 4:00 p.m.
