Fun and beautiful trail with a lake at the end. Stunning views some uneven ground but overall a great trail. A bit muddy after lots of rain.

Fun to ride up, one of the easiest to get up to the upper lake

I went hiking here with my 9 year old daughter the day after a light rain. It was mostly overcast. The trails had a few puddles, but were not muddy. We saw runners and bikers and a few other hikers. We saw deer, turkey, quail, newts, and many beautiful flowers. There is poison oak and poison ivy along side the trail; and mountain lions are known to be in the area. This trail has a pretty decent incline for the first mile or so and then a steep incline leaving the lake area, but there are plenty of benches and picnic tables for resting. An outhouse is located at the start and end of this trail. There is a fee to enter the park.
