First off, it's difficult to find. There are no signs pointing to the park until you're already on the road to the entrance. My Nav system led me miles away to a closed road that may at one time have gone into the park. The only way I found it was to put the name of the road it was on into the nav system.
Long story short: the only road into the park is unpaved, and no matter how slowly you drive on it, you'll kick up a bunch of dust. The plants along the way are so covered with dirt that they look like papier-mache models.
The trails are poorly marked, and don't have any directions along the way. It's like the park was started but never finished, and then abandoned. The park ranger didn't even know how to get to the loop trail - he just said "I think it's over there."
My wife and I spent our whole time in the park trying to find the trail. This place may be great if you want to get lost and pretend you're in unspoiled wilderness, you might like this. But if you'd like a nice environment with fun hikes and well-marked trails, avoid this one at all costs.
