I've been about four times in the past 6 years. Two times stayed two nights. Always in April or early May. The other two times stayed three nights so we could dayhike to the Colorado River. I'm a fairly decent hiker and pretty well-experienced backpacker, (35 years worth) so it was never that hard for me. I think of it as a pretty laid back sort of hike. A couple times when I went I was sort of out-of-shape for me, so I had to stop a couple times for 5 minutes or so when hiking out.
It is a hike that a lot of people do who do not otherwise go hiking or backpacking. This is understandable due to its being one of the most beautiful places on Earth!
With my background, however, it's just one of many backpacking trips I'll be doing in a given year.
Thus, it is with some amusement (and occasional annoyance) that I react to comments from others on the trail, and when arriving at the rim. I don't know of many other hikes one could do that, when you get to the top there stands some (random) chubby greenhorn newbie chick who has never met you before cheering you on, going, YAY! YOU MADE IT! It's really sort of offensive.
Most people along the trail assume you're just like them--that you think it's hard, too. That it's your first time out there, too. That's one of the things I dislike most about going there. It's really not a serious backpacker's kind of place to go.
It's okay to be a newbie, don't get me wrong. Everyone's a newbie at something. But why is it that newbies always seem to make so many incorrect assumptions about other people?
