An abandoned rubber plantation turned lush oasis, Tropical Spice Garden features 500-plus varieties of herbs, spices and flowers. Highlights here include the spice terraces, where visitors can learn about medicinal spices and herbs; the tranquil bamboo garden, where tea is made over a charcoal fire; and the Heart of the Garden, in the rain forest, where a giant swing beckons. The garden can be explored independently with an audio guide or on a tour led by a garden staffer.
