If only we could be Mary Poppins for one afternoon—we'd soar over people's gardens, make way through the trees, maybe even befriend a few birds.
It turns out we can—well, at least the part about wandering through the treetops. Here are four "canopy walks" that make it easy to walk from tree to tree at an altitude typically reserved for birds. Blending innovative design with natural surroundings, each of these structures offers unusual aerial views of the trees, animals, ground, and sky.
如果我们能变成“玛丽-波平斯”(迪斯尼动画中的玛丽阿姨)一个下午，我们会翱翔在花园上空，飞过树梢，或许还能更几只鸟交上朋友。
现在这成为现实，好吧，至少我们可以在树梢上徘徊一下。以下介绍的四条“树梢步道”使得我们更轻松地在离地一定高度地方，在树与树之间行走，而这样的空间从前是留给鸟儿的。将创新设计融合到自然环境中，这些结构令树木，动物，地面与天空呈现出不同寻常的视觉效果。

The series of suspension bridges, treetop viewing platforms, and forest boardwalks are suspended up to 200 feet; the waters of Fitzsimmons Creek rush below.

The experience is described as "floating through the hardwoods," where spectators can see a wide variety of flora and fauna, from trillium to flowering trees to red-tailed hawks.
