I am planning a trip for next spring and I am curious about the southern part of the state?We are planning on spending a little time at the grand canyon and then back up to CO.Is it just as nice down towards the border or do you need to be a little more north towards Denver?I want to some nice xc trails,hiking,hopefully some dirtbiking,and oh yeah family stuff.....any help would be appreciated.I am going to try and find some info on google and such but I figured this would be a good start..
