Originally an extensive library, art, and botanical collection privately shared by Henry Edwards Huntington and his wife Arabella, The Huntington opened to visitors in 1928 shortly after their deaths and is among the most celebrated independent research libraries in the world. But even if you’re not coming here to witness, say, the 15th-century Ellesmere manuscript of The Canterbury Tales or paintings by Dennis Hopper and Andy Warhol, you’ll have plenty to explore on the 130 acres of botanicals, sectioned off into over a dozen themed gardens. From a moon bridge and ceremonial teahouse at the Japanese garden, to the largest outdoor collection of mature cacti and succulents in the world at the desert garden, you’ll be spoilt for choice.

Designed by the Olmsted brothers (sons of Prospect and Central Park designer Frederick Law Olmsted) and opened in 1911, the Brooklyn Botanic Garden is one of New York City’s crown jewels. The garden stretches across 52 acres and holds over 14,000 types of plants. Come spring, the grounds burst with color, namely the 200-plus cherry blossom trees that bloom in April, and the lilacs, bluebells, and peonies springing to life throughout May. In July, visitors can lay out a blanket and enjoy live jazz in the evenings.
