I mistakenly thought the sun rises at 5:40am and thus arrived at 5:25am to start…in the dark (actual sunrise is 6:12!). Luckily I had a headlamp. There are 4 stages to this hike:

1.5ish miles of rather rocky trail.
~2miles of pretty smooth trail but steeper incline, ascending to the Saddle
flat/descent towards the base of Cucamonga (not sure the distance but you drop from 7650 to 7200)
The actual ascent of Cucamonga

It took me almost an hour longer than Mt Baldy. Probably because the rocky part is slow going up and down, and the climb back from 7200 to 7600 after descending Cucamonga. Started 5:25am, reached the top 9:20am, finished 12:10pm.
