"Carlos Thays Botanical Garden The red-gravel paths that wind among 6,000 plant species, past a babbling stream, and into deeply shaded areas may make you forget you’re in the center of a loud, bustling city. That said, many visitors don’t know that the Botanical Garden includes a small butterfly garden. It’s closed during the week, but you can still peek over a low wall to watch some 50 butterfly species flit about their business. And for one glorious hour, from noon to 1 p.m. on Saturdays, the gate is thrown open and the public is free to walk sunny paths among shoulder-high flowering hedges as colorful, flirtatious butterflies alight on amused visitors’ heads, shoulders, and arms.
