First ride here today. Did most of the trails with the exception of red and orange which I understand are "expert" level. Must say, I'm extremely impressed by this place. It isn't a huge network but it has a nearly perfect combination of hard climbing, fast and flowing descents and flats, and technical rock and root sections, some of which are quite serious. Generally not too tight so you can hold some speed through the turns. There are play areas off the main trails if you keep your eyes open so there are plenty of stunt opportunities if that's your thing. Otherwise GH strikes me as a true cross country park with technical features ranging from easy to advanced. I think any level of rider with the exception of absolute first timers will find these trails fun and challenging, but intermediate riders will probably get the most out of them.
I rode it with a hardtail 1x10, 33 tooth up front and 11-36. I found myself under geared and dismounting at the steepest portions of several climbs... But if you're stronger than me they're doable at that ratio. In fact, a strong single speed rider would probably love this place. I rode it with 100mm fork up front which I thought was perfect. This said the trails are so varied that anything from full sus trail bikes to fully rigid SS would be fun and doable depending on your skills and style. Only saw maybe four or five other people out there, only one other biker.
Similar feel to Hartshorne Woods but with more sustained climbing and exposed rock
