How much time do you need for a full walking tour of Peradeniya Gardens?

A well-rounded walking tour to really appreciate the main highlights of the Peradeniya Gardens needs an absolute minimum of two or three hours.

Since the grounds stretch to nearly 150 acres and include more than 4,000 species of plants, rushing through in less than an hour leaves you stuck with only the main avenue. People keen on botany, bird watchers, and professional photographers often spend four to five hours, quietly moving along the outer river edge pathways, visiting the orchid house, and taking in the huge bamboo collections.
