This was one of our stops with Boyce tours. The Andromeda Botanic Gardens offers two different tours. "Iris", the shorter one, is about 30-45 minutes, depending on your walking and reading speed, and "John" takes over an hour, from what I understand. We took Iris since we were on a schedule. The gardens are beautiful and packed with many streams, arbors, ponds, rocks formations, and little bench areas for pictures and rest. The flowers and plants are wonderful and plentiful. There are orchids, heliconia, palms, and many tropical and exotic plants.
The quick history lesson: Horticulturist Iris Bannochi left this 6 acres of garden to the people of Barbados to be run by the Barbados National Trust in 1988. The blooms and exotic plants are from all over the world. If you love nature, this is a "must" on your to-do list.
