False Kiva is a Class II archeological site located in an alcove in Canyonlands National Park. It's also known from the famous photograph by Wally Pacholka, showing the milky way in all it's glory. When you get there you'll be amazed by the silence of the alcove and the view ahead. You'll have a view on the Canyons and the Candlestick tower in the distance. The best time of day to photograph is late afternoon, certainly take a good hour to wait for the good light to drop.
It's not a very difficult trail, some people just get confused by the trail itself & end up at the rim above the alcove, instead of on the trail that leads to the alcove itself.
Park in the pullout at the first waypoint, walk back a couple hundred feet & you'll see the very obvious unmarked trailhead on the other side of the road at the second waypoint. The trailhead itself is located between a bunch of branches that are braided together, it's pretty obvious when you see them. This is something the rangers of the park did to mark the trailhead.
The trail is very easy in the beginning, almost promenade-like. It's very obvious to follow, although an outdoor GPS device will make it even easier of course.
Keep on heading down and you'll eventually reach the rim. You'll need to follow a path that leads down the side of the canyon. It can be tricky from time to time because of all the loose stones, make sure your footing is okay before you descend!
Anyone with a fear of heights may want to think twice about this part, you'll have to come to grips with it. Once you descend, you'll see the alcove on the right and above you. You will walk down to a ledge can freak some people out, but don't worry. Walk all the way over to the small trees and you will see the path that leads back up into the alcove itself.
In October 2012 I did this trail again and the trail has been maintained a lot better now. There are a lot of cairns to show you the way, although some parts might be a little unclear at first. Just keep looking and you'll find the next pile of stones within 10-15ft or so.
