Sir Seewoosagaur Ramgoolam Botanical Garden is considered the second best botanical gardens in the world after London's Kew Gardens. But while London needs greenhouses to keep the plants, the Pamplemousses is open air. There are more than 600 species of trees and 80 species of palms, including the largest specimen in the world (a 40 m tall Queen Palm). The garden was founded in 1735 by the French and expanded by the British. There are some quirky corners, like the lane with trees planted by country and world leaders like Nelson Mandela, Kofi Annan, Indira Gandhi… and Robert Mugabe. It is a good idea to hire a guide, though it can feel like the guide has a story about every single plant.
