Note that you have to get a permit to hike to Cucamonga, but not to hike Icehouse Canyon. The link for the permit is on the blog post on SoCal hiker. It was an easy form to fill out, just make sure you put your email in the comments so they can email you the permit. Parking fills up early so make sure you are there before 5:30 am. Icehouse Canyon to the saddle is still busy because there are many trails that connect to this one, but once you are on the trail to Cucamonga, there were not many people, which was nice. The switchbacks up to the peak are still sketchy and some parts have loose rock. It was a nice, sunny day and the trees are changing to fall there. There was some haze from the fires, but it was clear at the peak. Just note that there is no water from the switchbacks on Icehouse Canyon saddle to the peak so make sure you bring enough water.
