wide, maintained fire roads, with a scenic trail about a mile and a half in, just follow the signs. Plenty of scenic shots, and birdwatching, along with a nice sweaty ride. bring water, and a camera.
exit I-215 onto ramona expressway east. continue about 10 minutes up over mountains, (turn headlights on, they will give you a ticket!) make a left on davis st, the first light after you come over the hills. It will turn into a dirt road, and after about a mile, you will see the wildlife center on the right.
