Explore New Heights. There are many definitions for a zip line canopy tour out there. Here's a glimpse into the ultimate tree top zip line adventure known as Timberline Adventures in the Coeur d'Alene/Spokane Area. We start off by taking you on a fun four-wheel adventure to the top of the mountain and once you take that first step onto our beautifully constructed tour, your feet won't touch the ground for the next 2 1/2 hours. Towering high in giant Ponderosa Pines and Douglas firs, this tree top canopy tour let's you soar with the eagles. Surrounded by natural bald eagle habitat and over-looking beautiful Coeur d'Alene Lake, you will be immersed in mother nature. Lets ZIP!
