My trip to the Grand Canyon was tailored for solitude. We drove hours to get to a trailhead on the North Rim, hiked a a steep trail down, camped (by a hard-to-believe falls/spring), and hiked up and out by moonlight to avoid the heat. I don't mean to sound hardcore - I'm really not - I just like solitude and that's how you get it.
I'm ambivalent about this particular proposal. Exposure to nature creates naturalists. At the same time people ruin nature - the experience of it and it's physical environment. It's a balancing act and I have no idea if this is too much or too little.
