They've added a parallel path for the Cactus Rocks Trail, making it into a loop. I actually ended up hiking every trail in the place today. Started out at the usual Cactus Rocks interpretive nature trailhead, took the Vista Knoll semi-loop, then walked out the Ridgeline trail to the observation deck and back before taking the other side of the Cactus Rocks loop on the return trip. Lovely area as always, when the traffic on 1431 isn't too disturbing. Saw only one other hiker out.
