We camped here this weekend, which is the latest we’ve gone before the winter months. This past week had record high temperatures for all of Southern California, so I can’t say how representative our experience was compared to typically late fall trips in other years. The temperature was warm during the day, but we definitely brought layers and adequate sleeping gear for the night. Even though it was 79 degrees in the day, temperature got down to 54 at night. We were surprised to find the campground sites mostly claimed. Probably 75% full by Saturday afternoon. Again, this experience might be an anomaly due to the warmer weather
