Well, KOFA was great.
It's between Yuma and Quartsite on 95.

I put some pics up on the site.

No paved roads in the refuge, or any facilities. Roads (trails) ranged from washboardy to downright horrible. Even in my Jeep, I had some tough spots. To see most of the refuge, 4wd is the only way.

Finding great places to camp was never a problem, and I always had spots to myself, and all had spectacular views. You are permitted to make fires this time of year at least, though I never did since it rained almost the whole time.

I saw few people, most were limited to better trails, and the more remote trails were totally empty.

Backcountry hiking is fantastic, rock climbing also great. And at this time of year, the place is so green, it's kind of incredible.

I would highly recommend KOFA.
