Unbelievable
I simply can't describe this place in words. I've spent a week out here for the last 4 years and I'm going again this October. This place is my #1 recommended place on this site (as of right now).
I want my ashes spread here. It's the quietest, most peaceful, remote place I've ever been to. It doesn't feel like earth. More like the surface of Mars. Watch the sunset behind the high desert prairie. Explore slot canyons that you can barely get through with a backpack. Visit Cowboy Camp which is... well... an old cowboy camp. Don't move or take the artifacts.
Few things to remember: There is NO water, so pack it in. They recommend a gallon a day. That's a lot of weight, but you will use most if not all of it, depending on weather and activity level. Also, in the fall months, it is perfect during the day (high 60s to high 70s) and falls to 30s at night (occasionally 20s). So dress in layers and pack appropriately. I highly recommend visiting the national park website and reading up before ever venturing out into the backcountry.
Lastly, if you're the kind of jerk that takes spray paint or a knife into the backcountry with a plan to "leave your mark", don't go here. Don't ruin the beauty. No one cares if you Luv some girl named Rachel 4 Ever. Write her a letter. Pack out your trash and TP.
