A nice hike that started on Black Friday at 10 AM. We drove the long way from Rancho Cucamonga to climb this. The hike started in the fog and then we climbed up slowly through the woods, getting views occasionally. After climbing through dense fog, a creepy forest, and a meadow of manzanita, I reached Islip Saddle. Then I climbed through the dense fog to the summit. There was amazing views into the valleys occasionally and then after passing through the trees we reached Mt Islip after turning right. The summit had amazing views, a can, and the summit shelter. Then we climbed through some fog and then passed some amazing views into the desert. Then we climbed down to Windy Gap. After descending Windy Gap, there was a dangerous section and then we descended past a benchmark and then climbed back down to the trailhead.
