You need to know that this is *not* the "old military trail" on the east side of the lake, but rather a newer trail system on the west side, which is where singletracks plots it--follow these directions. The older system is overgrown and not maintained (debris every ten feet), not suitable for riding, but you could hike it if you enjoy ticks, poison ivy, and bushwhacking.
The west side is typical terrain for the area, very similar to Clinton Lake or Shawnee, but with dedicated sections for different skill levels. No true elevation around, so it's at a "lake" with turns that are unnaturally tight with occasional roller coaster grades that are short, too rocky, and too steep to enjoy for my taste, with switchbacks that badly constructed. The trails are cut wider than other places around here, so bar width is rarely an issue, except in places where a random tree is oddly left a a "feature," and a few off camber sections that hug trees on the down slope. Spider webs at face level most of the summer, and you're likely to contact poison ivy (similar to Clinton). I don't like the advanced trails here for the same reason I don't like other advanced trails in the area. No flow. The turns don't follow the terrain, so it's turn, turn, turn, turn, then hammer up something too steep and rocky if you can--but you often can't--so then it's hike a bike. Repeat. Same with downhill, very short then ruined by tight turns. The easier trails are similarly too tight. It is one of the best systems around, but the riding around here just isn't the same as out West (obviously) where I learned to ride. Better for trail running.
