Interesting trail. The good is that it offers a wilderness experience close to downtown. The unpaved trails feel like game trails with just enough hills to keep it fun. Some of the bad things are that there is indeed homeless people camping out, although if you stick to the main trails it is unlikely you will stumble across any. I only saw two trail markers but it's pretty hard to get lost. I went on a rather gloomy day, so the whole experience had a bit of a fallout 4 vibe.
