Chantry flat trail head is closed for a while due to bobcat fire so took Mt Wilson trail head instead. Trail is half exposed. We started at 6am, got warm quickly when the sun came out. We def over dressed.  One layer of long sleeves and thin hiking pants r enough. Very warm when we descended, dusty. Not a challenging hike. When we got close to the top, we got lost for 15min because we went w the wider road where car can drive up, we headed back a little and found the narrow trail and started to climb. There r water fountain at the summit and bathroom. Cosmic cafe is not open due to holidays. But I heard from other guys that they said it’s never open, I am not sure.
