Last time I did Spring Creek the Rock Garden a WJ mildly lifted went up the bypass, they got stuck worse as it was narrow and rutted out. The rock Garden at least it is wide and can take many different lines and zig zag through.
I love the 3 trails up there Red Elephant/MIll Crek/Bill Moore (Empire loop), spend all day doing them, beautiful area, lots of different things to crawl over etc. I just fall back on them so much if I cant figure out where to go that I realized I need to find some new fall backs. They are also SUPER busy on holiday Weekends.
Directions with taking Red Elephant;
Go up Red Elephant (say hello to the rude angry looking residents that live off the first part of the trail.) Go up this narrow steep hill and watch out for the rutted out area with rocks/boulders and the 500 steep roll off hill. Make your way up the 3-4 tight switchbacks. When you get to the top and go through the dense tree area, you will come to a meadow open area with the first Y, take a right if you want to go the easy way (counter clockwise) on Mill Creek (going down the hills with the rocks/cliffs) or pass that Y and come to the second Y and take a right to the funner way (clockwise) make sure you stop at the "Empire Hilton" either direction you take and gander at the bug infested beds you would never sleep on and say hello to "Rudy" the bear. Either direction you go when you come back to main road after completing Mill creek head west (right) until you come down a hill and another Y take a right to Bill Moore Lake. Pose in the old barely there cabins near the lake.
I have down this trail so many times I can do it half blind.
(BTW Irving I have never seen anyone get spotted on the Empire loop even in a stock XJ. Your should be good.)
