Likely In-Season!
I was introduced to this trail when I hiked the similarly named description to Leopold Point. However, since that was written up, a full and newly built trail from the end of the Incinerator Road to the San Pedro Vista has been constructed. It was built in late 2012, or so an internet resource states, but I suspect it may have been a social trail before that. This Trail is not signed with a USFS Metal sign at the San Pedro Vista, but is signed at the end of the Incinerator Road as Trail #18A, Incinerator Ridge Trail. There is an AZT signpost at the start of the trail at the north end of the San Pedro Vista.

Overall, this is a short segment of trail with outstanding views off of either side of this generally north-south trending ridge. The trail is short, but can easily be combined with other trails to produce an out and back to a logical high point of Mount Bigelow, or loops using other trails. Views range from the Pinaleno Mountains to the Tucson Mountains, The Superstitions to the Santa Ritas, and possibly as far away as the White Mountains.

Trail #18A leaves from the San Pedro Vista and climbs up switchbacks and steps along the ridge line, around Barnum Rock, just below Leopold Point (accessed via a social trail), up over what I believe is Incinerator Peak, and then descends slightly to what appears to be the USFS designated trailhead at the end of the Incinerator Road. This is the only spot in the forest I found a sign naming the trail, and at present the forest's website has no information on this trail.

Though this trail is considered to end at the sign, or begin there, the Kellogg Mountain Trail #45 makes a logical continuation to head to Mount Bigelow. Because you are never really far from the Catalina Highway, you might hear traffic for most of the hike, especially on weekends. However, this does allow for easier starting and stopping points using other trails.

Finally had some time and clear schedule to get Sierra up to camp a night on Mt Lemmon. Chose Leopold Point and Barnum Rock as our first hike, to show her some sweet high country views. really beautiful day up there and she loved these peaks.

we also walked the climbers route out to the base of the barnum rock wall and saw some climbers

took AZT bypass to incinerator ridge, then kellogg mountain and bigelow trails to the bigelow FSR. ran that down to the observatory then down and around the white tail campground. came back and banged out some peaks: unnamed 8400 tower peak, mount bigelow, leopold point (took a stupid way down :? ) and barnum rock!

this is a very fun route. nice and cool up there early then fairly mild all things considered. was done before noon.

Green MT TH to MT Bigelow
I hiked from the Upper Green Mountain Trailhead, over a hill, down to the San Pedro Vista, and then up to Mount Bigelow using the Incinerator Ridge and Mount Kellogg Trails. I walked to the Butterfly Trail Trailhead on the northeast side of Bigelow, down a section of that, and back to the Green Mountain TH with a stop over at Leopold Point. I also took a part of ht Green Mountain Trail, and the cairned extension back to the trailhead. Signs and trails are a little confusing in this area. I think the FS did themselves a disservice by creating a multitude of smaller named trails, instead of one or two longer trails with multiple access points, which should be signed to clear things up. Oh, well.

Nice views, as is to be expected on this section of ridge, but Rose Lake Campground was full and everyone was feeling the need to have afire with green wood, or so it seemed. Smoke was thick and hiking down the smell was strong. Oak Creek Canyon(Sedona) in August strong. Lots of nice bird calls near dusk, a bees swarm passing by at the start, and heavy weekenders (crowds, not individuals).

I also did a few off trail excursions to look at forest reproduction, but I'll hedge low on the AEG.
