beacham trailhead at the camp grounds is mostly fireroad up to where you cross the lake dam, the overlook section spurs off at a couple points. Then the trail turns to singletrack, few rideable techincal sections nothing to serious.
just east off higway 62, first entrance passes the ball fields and has a couple trail entrances, just past that entrance there is another one that goes up to a camping area, where the beacham trailhead is.
