...We want to do some good trails, even ones without my truck because the other 2 are not bad. ...
Well, 'good' is in the eye of the beholder. My wife thinks Kane Creek is good, because it is pretty, and the shelf road does not have much exposure. I like that too, because of all the sandy water play at the bottom. She likes Gemini Bridges, but I find that a bit of a snoozer. I like Buttscratcher on Gold Bar Rim, she doesn't.
I think Cliffhanger is good because it has some harder sections, but not too much exposure. Going out is sometimes harder than coming in, so be prepared. My wife prefers to walk it - she does not care for the parts I like. We both love Elephant Hill, but that is a commitment and the trail is not very hard. Just incredibly scenic. Long drive though.
We both really like Poison Spider Mesa. Just enough challenge, not much exposure (except on some optional routes).
Some feel Behind the Rocks is good. I don't. Glad I did it once, that first obstacle I shall never do again.
Some like Moab Rim, others find it a shorts filler. I don't seem to be intimidated by it, curiously. I like parts of Hells Revenge, but the one tippy obstacle on the way out is no fun for me. Some like Hells Gate, but I ain't a gonna do it ever.
See what I mean?
Name some trails around here that you like, and your experience level, and we could maybe make some good suggestions.
