Beginner trail for kids

Is there a good beginner trail in the seymour/fromme area for kids to start on. My kids have 16 and 18 inch wheels so I'm looking for something flat but that still has the "forest" feel. Ideally also something without a crushed rock surface.

Suggestions?

Highschool off Hyannis. Figure out the area yourself first if you dont know it. There are easier ways through as well as harder ways. Its a ten minute loop for you, likely an hour with kids.

Oh, flat. Try the trails on the west side of Lillooet road off the crushed gravel. North of the cemetary.

Circuit 8 is good, but a bit of a ride for a real little guy to get to.

I saw that Delta Watershed is back open. Bit of a drive, but great for little ones starting out. Not certain if it's still there, but it had a slightly downhill little jump trail. If not out by elementary school is pretty flat.

Another option is Hyannis out to and around where it splits from trail trail down to the river (Bridle, I think). Used to be a 3 foot wide board walk really low to the ground. I had my kids start there, one still had training wheels on. Talked about it for ever about riding on a mtb trail.
