Forget the hilltop meadow from The Sound of Music. To make your heart sing, no passport is required to hike amid Texas’s colorful blossoms on the trails of the Lady Bird Johnson Wildflower Center. Created when the former First Lady and the actress Helen Hayes searched for somewhere to preserve North America’s landscape and teach the importance of conservation, the center has become an outdoor classroom as instructional as it is beautiful to behold. Attracting butterflies, birds, and wildlife of every sort, the trails join with various structures to fulfill Johnson’s vision of an all-natural, public garden in Austin. Eco lovers will also swoon over the environmental research plots that dot the trails.
