My wife and I are in our late 50's and in average physical condition. We visited Red Rock last year and hoped to do this Ice Box Canyon hike this year. We found it helpful to visit in late March this year vs late May last year so the temps were cooler. We also found it helpful to have walking sticks (pair of name brand light metal sticks from Walmart cost about $20 a pair), ordinary work gloves (helpful when scrambling on big rocks and boulders), and good hiking boots. Most folks in better condition seem to be able to do this entire round trip hike in about two hours. We gave ourselves four hours and took our time, very relaxing and enjoyable pace. The trail from the parking lot to the entrance of this canyon is clearly marked and fairly level. But once you enter the canyon, the trail is not as clear and folks seem to make their way along and through the small creek any way they can, sometimes climbing over large boulders, other times pressing their way through brush along the banks. Once you reach the actual area of the "Ice Box" near the end of the canyon, there is a beautiful pool of water and at least in March, there is a thin waterfall in two sections that feeds the pools of water. My wife stayed near the lower pool just outside the actual Ice Box area while I tried to climb a bit higher. But I reached a point where there was a bit of rock scrambling that was just a bit too risky for me (worse case scenario would be slipping off the canyon wall and falling about 10-15 feet into the pool of water!), so I decided not to risk it. But others who were younger or in better shape seemed to navigate this final bit of climbing without much problem! Even though my wife and I did not make it up into the final Ice Box location, we still felt very blessed by the view from the lower pool where we could see most of the Ice Box. It was well worth the hike!
