Running between April 7 and 27, families can track down giant hand-painted eggs, collect symbols with the help of a code-breaker kit, and crack the code for a chocolate treat.
The trail also offers the chance for children to engage in craft activities, such as creating spring chick finger puppets.
Young gardeners can plant a mixture of lettuce and sunflower seeds to take home and grow.
The garden will host live entertainment, including storytelling, a show by the Curious Investigators, and a bubble show from Paris Bubbles.
There will also be the Guess How Much I Love You™ garden adventure trail.
Children’s tickets cost £5 and adult entry starts from £14.50.
RHS members and children under five can enter for free.
A £2.50 charge applies for a code-breaker pack and chocolate treat.
