Great hiking trails, not overly built up, and yes, there might be horses
There are about 20 miles to hike in this park and there is a special camping area for folks who bring horses. I was here in the spring but was told fall is the best time because of the changes in the trees. I believe it and hope to make it back some day. There are showers and water for campers which was a nice luxury. There were 5 people on horseback when we were there. You can mountain bike here but they do not allow swimming. At only $5/day for a permit this place is a steal. The caves were not what I expected. There is a fair amount of graffiti from local kids.
