Historic Garden Week in Virginia offers the opportunity to visit beautiful homes and gardens in the state, ranging from classic to modern. Horticulturist Chelsea Mahaffey leads this tour of Oak Spring, the former home of philanthropists Paul Mellon and Rachel “Bunny” Mellon which is usually closed to the public, and the University of Virginia’s Blandy Experimental Farm, which includes the State Arboretum of Virginia.

From the desert gardens to the red rocks of Sedona, the northern mountains to the depths of the Grand Canyon, this 6-day spring adventure offers outdoor enthusiasts an itinerary filled with education and scenic beauty led by geologist and study tour leader Wayne Ranney.

Assateague Island National Seashore and Chincoteague National Wildlife Refuge are home to natural splendor, cultural treasures, and coastal charm. Spend two days with naturalist and educator Liana Vitali immersed in island life, exploring the natural wonders the barrier islands have to offer—and hear the lore of the Chincoteague ponies’ origin.

Entire ecosystems rest on the shoulders (or tentacles or jointed exoskeletons) of animal babies. Biologist Danna Staaf invites you to explore these tiny lives and discover some of nature’s most ingenious workings. For example, a salamander embryo breathes with the help of algae inside its cells, the young grub of a Goliath beetle dwarfs its parents, and the spotted beak of a parasitic baby bird tricks adults of other species into feeding it. Our planet needs them all, the maggots as much as the kittens.

Life thrives in the deepest, darkest recesses of Earth’s crust, and it is unlike anything seen on the surface. Discovered only in recent decades, intraterrestrials—bizarre subsurface beings that can live for millions of years—can exist in boiling water, pure acid, and even bleach. Biologist Karen Lloyd offers a firsthand account of the remarkable hunt for life beneath Earth’s surface and how new discoveries are challenging our most basic assumptions about the nature of life on Earth.

Naturalist Matt Felperin leads a two-day adventure for nature lovers that explores the Delaware Bay and its environs, where the diverse life of a tidal marsh and the expanse of the bay come together. From observing horseshoe crabs breeding by moonlight to visits to the Bombay Hook National Wildlife Refuge, the Dupont Nature Center, and local beaches, the tour offers insights into a habitat in which a wide range of migratory shorebirds play a key role.

For 115 years, Longwood Gardens in Kennett Square, Pennsylvania, has stood as one of the world’s leading collections of plants, showcasing botanical splendor and state-of-the-art glasshouses. Spring, when the gardens come alive with blooms and birds, is the perfect time to experience its beauty. Karl Gercens, Longwood’s conservatory manager, leads a specially arranged curator’s tour of the outdoor gardens of this historic du Pont property, where azaleas, poppies, and a host of flowering shrubs greet the season.

Soar into the fascinating world of North American shorebirds, waterfowl, and songbirds at the Bird House in the Smithsonian’s National Zoo and Conservation Biology Institute. In three indoor walk-through aviaries, visitors are surrounded by migratory birds as they explore realistic re-creations of key habitats that support them during their annual cycle. Brian Evans, an ornithologist at the Smithsonian Migratory Bird Center, and members of the Bird House’s animal-care team lead an exploration of the exhibitions and discuss the science that informs bird conservation.

Whether deciding on lunch or a career, changing our routines or other people’s minds, it can feel difficult to make the decisions that align with the things we care about. Neuroscientist Emily Falk, author of What We Value: The Neuroscience of Choice and Change, explains how we can work strategically with our brains to make more fulfilling choices by connecting our decisions with our core values, which can make us less defensive, broaden our curiosity through different perspectives, and spark innovation.
