I just rode rockhouse this past oct. The green and blue trails would be a piece of cake, the black and single track would be a challenge, pretty rocky. We rode on a thursday and pretty much had the place to ourselves. I'm sure the weekends are a little busy and you will have to watch out for traffic . We had alot of fun and are hoping to check out some of the other locations. We mostly rode the black and single tracks. but we we did catch several green and blue trails.
