Mountain bikes navigate all those surfaces and they have the same exact drivetrain configuration of your Villager trike. I would want to know how the trails are laid out. There is a park with asphalt trails that I cannot ride with my recumbent (not a trike) because there are sharp bends with elevation changes that are simply impossible (for me) to navigate without dismounting. The further a surface gets away from fully paved the greater the possibility that it just might not be navigable by a recumbent trike. You would know more than us. But, given my druthers, I would much rather HIKE a stone dust trail than ride on one. To be honest I don't even ride asphalt trails. I ride roads exclusively.
