Moir Garden is a small, old-fashioned garden on the Kiahuna Plantation grounds, known less for tropical lushness than for cactus, succulents, and a quiet sense of south-shore history. It is a gentle detour rather than a must-see.
Stop if you are already nearby or if you like gardens that show a private, accumulated character. Travellers expecting the drama of the National Tropical Botanical Garden should set their expectations lower.
