Borges Ranch Flowering Plants

May 25, 2004

This "trail" starts at the back right end of the gravel parking lot located at the far end and above the Boundary Oaks Golf Course parking lot. Take the road leading to the shooting range and bear right into this gravelly lot. Start at the sign, walk to the road above and turn left. Cross the road under the high-tension lines and continue at the same elevation across the road. This path eventually takes you to a level area after two or three short slippery downhill patches. Continue on this level for about 3/4 of a mile and then take the sharp steep path up to the next level. Here, there are several flowers and from there you may re-trace your path back to your car.
