Did some research, and I got to say, I've mistaken this for Cold Springs Trail. Even though there's a sign at the trailhead saying McMenemy and Cold Spring Trail, those two trailheads are much further up than expected.
Enter this on Google Maps for the Trailhead:
Riven Rock Rd & E Mountain Dr, Santa Barbara, CA 93108
At the beginning half of the trail, you'll hug the edges of many private mansions. Just follow the water and you'll be fine.
Walk until you hit a junction with a sign for Hot Springs Loop and San Ysidro. Take a right and cross the creek. The walk up is difficult but worth it at the top of Saddle Rock. There's a bunch of rocks near the top, but nothing that requires rock climbing ability. Once at the top, you can continue on the right and go under the power lines and follow the dirt path, turning left.
There's a nice meadow on the side route on the right. It's quite a ways after the Saddle Rock Lookout, but it's also a pretty cool spot.
Eventually you can climb down and hit the Hot Springs Creek, climb down the rest of the way. It takes about 1.5-2.5 hours for a round trip.
Other than needing more signs, it's a good route. This website also has a pretty good map on the route. http://www.sboutdoors.com/saddle-rock-loop-west.html read more
