Ok, this 3-star review is for the structure of the GCW, most specifically the Skywalk, and not for the Canyon itself because it is BEAUTIFUL!
Different from the National Park, the GCW doesn’t offer a bunch of hiking options. You go and see the Eagle Point, then go to Skywalk, and then to the Guano Point, and that’s it.
The line for the skywalk was huge. However, when you’re inside, if you didn’t buy the picture package, you can go straight to the bridge. That means that you stay in a huge line for nothing while a bunch of people is waiting to have a photographer with them.
The bridge itself is cool, but the glass is all messed up already. You can’t take your phone or any camera with you, so if you have to pay if you want pictures taken there. Are the pictures worthy? Honestly, no. Most photos are taken with a terrible angle, and they keep the flash on all the time, so the flash reflects on the glass and makes your picture look ugly.
The Skywalk restaurant is okay. You can get a great view of the Canyon there. It took us 30 minutes to get our check, but it was okay.
The Guano Point has spectacular views of the Canyon and the Colorado River. You can go to the top of a bit of mountain, but there are no signed trailed to there. I gave up half-away because we were on the edge of the Canyon, thinking that we were on a trail, but we were not sure at all if that was a trail or not.
This place is cool if you have an extra day in Vegas and wanna check the Canyon; otherwise, I would recommend going to the National Park because there are not that many activities and hiking trails to do.
