The crown jewel is Toni's Treehouse, an elaborate multi-level canopy play structure built into a massive banyan tree, complete with suspension bridges and climbing nets. Kids can pump water through mountain stream channels, build boats from bamboo leaves, play musical instruments crafted from stone and wood, and explore succulent labyrinths. Paved paths connect the garden to miles of mild-winter subtropical walking trails with stroller accessibility. ## Similar picks in San Diego - [Lightscape at San Diego Botanic Garden (Encinitas)](https://grassyknees.com/san-diego/activities/lightscape-at-san-diego-botanic-garden-encinitas--listing-bd89d2017117cd6825e54bc3) — Nov 20 – Jan 3 · 5:00 PM – 10:00 PM · San Diego Botanic Garden, Encinitas · All ages · From $29 · checked Nov 4.
