If you've never experienced it and are curious, check out the ehike the park recently produced.
Part slide show, part video, part symphony (natural, and orchestral) performance, this eHike leads you from the floor of Zion Canyon nearly 1,500 feet up to the outcropping that is Angel's Landing. But the production is much more than simply a look at scaling this iconic overlook. It's an audio and visual portal into the ecosystem of Zion Canyon.
There's information on the geology that forms Zion Canyon and the forces that sculpted the canyon. You can watch a video of the Virgin River at normal flows, and one of a flashflood down the river bottom. There's a great shot (and even a short video) of Walter's Wiggles, a stretch of switchbacks that you have to negotiate, and information on the different microclimates and animal and plant-life to be found along the hike. Not only are you offered photos of the birds that inhabit the canyon -- from the Black-chinned Hummingbird and melodious Canyon Wren to the Turkey Vulture, Peregrine Falcon, and, if you're lucky, even the California Condor -- but also audiofiles with some of those species' songs and calls.
Naturally, there's also a video of hikers working their way along the section of trail where chains offer you something to hold onto. And for aspiring climbers, or those heading to Zion to climb, there's an interactive shot of three popular climbing routes, and some photos that will test your comfort levels in high places.
This is a great work of audio/visual interpretation.
