The Royal Botanical Gardens of Peradeniya
I was a little agitated by the $10 entry fee for the Peradeniya Botanic Gardens, but it didn't take me long after entering to realize that it was money well-spent. Peradeniya's are the most fantastic botanic gardens I've ever seen. Trees the size of sky-scrapers, flower bushes exploding in incredible color, giant palm trees that bloom just once in 45 years, and cannon ball trees with heavy round fruits were just some of the highlights. I've never been so bowled over by botany.
