Brandy,
To get to Lytle Creek, Take the 15 north to Sierra In Fontana, turn left, park at the truck stops. it's about 2000 feet there, the pavement ends about 10-12 miles at about 4500 - it continues as a dirt road that goes to the Ski lifts on baldy very hard to get lost
we usually do from somewhere in Rancho Cucamonga adds another 10 miles and 1000 feet. It a very gentle climb(lot easier than GMR), until you get pas Applewhite Campground
Suz, saw several male rides descending on my up. I did pass some female rides on the short rise just after the Valero on my descent
