Bear Flat
Like nearby San Antonio Falls, this hike falls into the “Taste of Baldy” category. The hike to Bear Flats is actually the beginning of the very challenging Bear Ridge route to the summit, which gains almost 6,000 feet in six miles. The trip to Bear Flats is a good workout in and of itself, with a lot of nice views.
From the parking area, pass the visitor’s center and follow the signs (small but clearly visible) to the Mt. Baldy trail. The trail ascends a dirt road, passing by several cabins and following Bear Creek. It switchbacks quickly up the hill, giving views of San Antonio Canyon, the Ontario/Cucamonga Ridge and the Inland Empire. Some of the switchbacks are pretty quick, so make sure you don’t miss them.
The trail leaves the cover of the trees for a little while, contours around the hillside, and goes back into the woods. After a few longer switchbacks, there’s another open stretch, another return into the woods, then after a creek crossing, you arrive at Bear Flat, a large green meadow with views of the peaks above.
The trail continues to the summit, but the route gets more and more challenging (if you are tired by this point, know that the remainder of the trail is even steeper). If you decide to continue, based on what I have heard about the Bear Ridge trail, you have my admiration–and sympathy.
For those whom Bear Flat is their turnaround point, retrace your steps down to Mt. Baldy Village for a total round trip of 3.4 miles.

Ahhh..The Bear Flats trail.To do it proper is a car shuttle from San Antonio Falls road to the Baldy notch.Published 16 miles and 6000 vert.Starts pretty,then turns into a grind.The gift that keeps on giving.Would recommend this trail as a warm up for those aspiring to do Whitney,same miles,same vert.Do this trail,and know a bit about crampons,and how to use an ice axe,and you got a shot at it.Rates up with Iron mountain on the damn hard walks.
