It's over 9,000 acres. In late spring (after we get some solid rain) several large "vernal" pools form. A unique shrimp, found only in this area, hatches during this time. Perhaps we'll go back and watch the action!
The trails are well maintained, and there are many of them, so seasoned hikers can spend all day (from sunup to sundown) and still not see it all. After Santa Rosa we took the back roads to Temecula, then south to Fallbrook for lunch and shopping. With weather in the 80's, it was a beautiful day indeed.
