Rainbow Canyon is a place that is well known to most regular park visitors, as just about everybody has looked down into it from the overlook at Father Crowley Vista Point. However, the canyon name is not as well known, since the hike has never before been recommended in a guidebook (as of the time of this writing). Rainbow Canyon is also sometimes referred to as Star Wars Canyon because it is part of the route used for military training flights in the area. In recent years, word has spread around that you can watch fast aircraft fly through and above the canyon, and that has resulted in aviation enthusiasts frequenting the area to do aircraft spotting. Tragically, on July 31, 2019, a Navy plane crashed into Rainbow Canyon during one such training flight. The pilot was killed and seven bystanders sustained injuries. Our thoughts go out to the pilot's family and to all of those who were injured as a result of this accident.
As far as hiking goes, Rainbow Canyon is one destination in Death Valley which I always thought had an awesome name but never expected to actually end up visiting to carry out a hike. The reason why is that it has always been known as a canyoneering canyon, having four major dry falls which all require rappelling down with lengthy ropes to continue. To break things down, Rainbow Canyon is divided into 3 sections -- Upper (mainly known for being accessible to canyoneers, but some hikers can find their way in), Middle (only accessible to canyoneers who rappel in), and Lower (known mainly for easy access for hikers). These three sections are all divided by massive dry falls. The head of Upper Rainbow Canyon basically starts out with the 1st dry fall (100 ft.). Next, Upper and Middle Rainbow are divided by the 2nd dry fall (170 ft.) and 3rd dry fall (90 ft.) which are done as back-to-back rappels. And finally, Middle and Lower Rainbow are divided by the 4th dry fall (20 ft.). I haven't measured these major dry falls myself, but obtained the information from various canyoneering web sites. So hopefully it is accurate (but do your own research before going if you are a canyoneer). During my Spring 2010 trip, I had the chance to solo hike the entire canyon over the course of two days. This report is for the upper and middle portions, while another report covers the lower portion. My decision to hike in this area came about when a friend invited me to hike Lower Rainbow Canyon with him. He ended up not being able to make it, but his off-hand mention of Lower Rainbow Canyon raised my curiosity enough to think to myself: "He mentioned Lower Rainbow. Well, what about Upper Rainbow?" While I was home during a break from my trip, I did some research and found a climber's report which shared details of a bypass which could be used to get into Upper Rainbow Canyon. This intrigued me, so I spent a few more hours researching the entire canyon, printed out a number of maps, and headed back to Death Valley. When I got there, I used the suggested bypass and this allowed me to get to the base of the 100-foot 1st major dry fall of Upper Rainbow Canyon and also overlook the middle canyon from the top of the 170-foot 2nd major dry fall. And I truly came to appreciate that Rainbow Canyon is unbelievably beautiful, as I enjoyed the view down into Middle Rainbow Canyon with walls colored by rainbow bands towering up to 1,000 feet on each side. Before heading back to my vehicle, I decided to walk the rim trail above the canyon for a while. As I walked along it, I came to a spot where it looked like I could scramble partway down toward the canyon floor. Sure enough, through trial-and-error over the course of a couple of hours, I figured out how to get down into the middle canyon. It was an incredible moment to set foot in the middle canyon for the first time. The scenery is magnificent from above but it is equally as impressive when viewed from the bottom. After this, I hiked up to the base of the 90-foot 3rd major dry fall and then headed down canyon until I reached the top of the 20-foot 4th major dry fall. I then had to rush back up canyon and make my way up the incredibly steep and challenging bypass to get out of the canyon before it was pitch black outside. Before I wrap up this report, I definitely need to share a word of caution about Rainbow Canyon. A hiker with basic bypass skills should be able to figure out how to get into the upper canyon without too much trouble. But reaching the middle canyon as a hiker requires advanced bypass skills and extreme caution. Most hikers will not be able to accomplish this. The map that I included does not show my exact bypass route, but it was drawn based on my memory. I was not using a hiking GPS at that time. So please be very careful and I would highly suggest not attempting this if you don't know what you are doing. In addition, as I am writing this report update several years later, please keep in mind that there could have been additional landslides which have washed out the bypass route that I used back in 2010. So it may not even be passable any more. This was a true Death Valley adventure that I will never forget. Our hike took place on March 10, 2010.
