Absolutely gorgeous! Best if you come in Jan/Feb when it's not to hot. My bestie and I hiked up here and were in love with all the gorgeous homes and how far you can see for at the lookout points.
Difficulty wise, this is pretty easy until you get to the part where it says "strenuous ahead". At that point, it's a lot of stairs!
One thing I really love is all the mile markers and cactus & plant identification signs. I felt like I was learning whilst hiking. My favorite was the teddy bear cactus, but no hugging those little cuties! ;)
Overall, 2 miles, not too difficult, great views and a solid workout. 10/10, would recommend.
