The Oxley site is a really nice site to camp at. I know it's only a primitive cabin, but only just barely. It has so many comforts that I wasn't expecting, it felt pretty luxurious compared to what I thought it might be. No water, no electric. No problem. Honestly, you hardly notice that while you're there.
So many little but smart decision to implement something like reflective tape and solar lights on the stairs. Or, backup cookware and plateware in case you forgot yours. The camplights in the cabin and in the outhouse to use when needed. Even a little stove. So many little things that just add up to make the stay as nice as possible.
Beyond that, being back away from the road was nice. You don't feel secluded, but it certainly feels private. Being half way up a large hill, you'll want AWD or 4x4 to get up it, but it's location is nice because going further up the hill on foot gets you to a flat landing that we liked to sit at and watch the sunrise hit the hills around us.
It's a great place for a couple, small family, or a small group of people. Would definitely come here again.
