The map as shown as of June 2018 does not reflect the actual trail. Go through the Powell Visitor Center and take a left out the back door to go to the Garden's 'front gate'. From there, the Hummingbird Trail, Botanical Garden, and Cactus Greenhouse will be in front of you. Wind your way along the beautiful paths and learn about desert adaptations, the families of plants you see, and pollinators. The cactus greenhouse features a spectacular collection of Chihuahuan Desert native cacti, the largest publicly accessible collection of its kind. A must see.
