Really good trail, there are lots of options so you can make it as hard/long as you feel like. Great views of the hills near the ritz Carlton and some evenings they have flute music playing at the hotel which echoes around the trail. The trail mixes with the lower/upper javelina trails quite a bit so read the signs carefully to stick to this trail. Bring lots of water- there is nothing en route.
There were very few people when I was on the trail- just a couple and their dog (the trail seemed very dog friendly!)
NO access to the park from Tortolita Estates-Cougar Canyon Rd...it's been gated, locked and shut down. Probably 20 or more Private Property-No Trespassing-No Park Access signs posted. It's Saguaro Ranch property, and looks like they mean business, installing massive iron gates to block anyone, and everyone.
