There's a short road/trail up in the Oakland Hills behind skyline. at the end of the trail is an entrance is a park, i just do a u-turn and go back to the entrance of the trail. fun trip but sketchy thing is the rocks and loose gravel on the road :/

Theres also lake chabot road but only thing about doing a night drive is the deers. ;/ rekt my bumper. Also at the beginning/end (depending where you start) is a police station

These 2 are my SHORT "mountain" driving fun
