I lived in Agua Dulce for 11 years and this place was in my backyard! I live in Castaic now, so it's really not far at all. I did all these trails and climbs in my Jeep at one time or another.
Sidebar: About that teenager. I wonder what he was riding, etc. ? Sad. I have been up that hill so many times.
