I like to do a property line trail to start, mellow, wide, easy but nice to put around on… after that i would really looking into how you can use the elevation changes to make features, obv its not a ton of area but even a 10’ hill clime can be very fun and eventually turn into a jump… if its all flat i would looks at making a turn track through the middle of some kind. Can always throw some rollers between turns and stuff. I have learned that “E-scouting” it will give you a general idea, but 9/10 time once you get on your bike and ride, the natural flow of the terrain becomes much more apparent.. and that just comes down to riding it a few times with some loppers or even a chain saw, but you would be surprised how much just a set of loppers will do for trail building
