Riding trails North West of Phoenix

Anyone out there familiar with some good riding trails NW of Phoenix are? Say Wickenberg area. I heard there is a trail that can take you from Wickenberg to Las Vegas. Our group is from the East side of the valley and we tend to ride the 4 peaks, Sycamore and Box Canyon area but are looking for something different. Been to Crown King and the Table Mesa area many times as well. Any feed back would be great.
Thanks
