Explore a marine dream of coral, kelp and coast with Inside the Tide!
Step inside this spectacular world of aquatic delights in our new immersive exhibition.
Combining the theatrical with horticulture, this exhibition creates a surreal, magical and playful display. Telling the stories of hero plants in three aquatic communities: Kelp Forests, Coral Reefs and Seagrass Meadows, wander through what feels like an under the sea experience and watch a pantomime come to life. Come face to face with giant sea creatures like the topiary blue whale, a chandelier of jellyfish or blue ringed octopus with interactive elements both children and adults will enjoy.
This year's display has also enlisted the help of hundreds school children from across NSW, who in 2021 created Codium seaweeds when undertaking educational workshops with the Royal Botanic Garden Sydney learning about the threats to coastal environments and how to best care for habitats.
Inside the Tide has over 20,000 plants on display and one of the largest living green walls in the Southern Hemisphere. Curated by the horticultural team at the Royal Botanic Garden Sydney and presented in partnership with Erth.
While you're visiting, let your kids explore the kid's corner where they can discover life's enchanting characteristics in the ocean. Activities include First Nations fishing, seagrass yoga and much more.
