What an interesting place! Mythical, informational, unique, and rocky. When doing some research online, found this place and decided to venture here as a family. I mean, how many people know there's even an American Stonehedge? I wasn't exactly sure what to expect when I arriving, but came with an open mind.
There was ample parking at the center, as when we went on a hot morning there were only probably five other families. You walk up to a visitor center, which has a good size gift shop attached. There is a cost to get in to the facility/trails/viewing area, I believe it was $14 for adults and $8 for kids. The employees were very welcoming. In The Visitor Center there is a short movie/film that visitors can view explaining American's Stonehedge. It'd be a good idea to watch prior to going out on the trails and exploring. The visitor center does also have restrooms, and a smaller information center, all adding to the experience.
When leaving The Visitor Center you're out on the trails, the first thing you encounter is a gemstone dig area for kids which is very nice if you have children. They let you keep three gemstones from your dig. Then you continued traveling up the trail and there is either a map you can use to guide you or they have a free online app you can download where it will read the information on the trail. There's about 25-30 different information areas, that you can read about/learn about. We decided to use the map but the people behind us use the app and it sounded very well done.
Exploring and reading map about the site can take about an hour; more if you take pictures and venture off to additional information on the trail. Lots of neat things to see and invision about the past. Although many of the structures are just partially there due to time and decay, the map does a good job of giving information. At the end of the trail of there's a surprising Alpaca Farm, with really friendly alpacas that just add to the whole experience! They really like getting their picture taken. They were so sweet.
With not having a ton of information prior to coming, this was a really fun experience! Even the kids who sometimes complain about hiking in the heat enjoyed it. Glad we went.
