After about a mile up the service road you reach the fire tower. The trail continues into the woods (blue blaze markers) at the bend in the service road right before turning to go up to the fire tower. However, the Trail is still VERY overgrown. I hacked about .2-.3 of a mile into it John Muir style but it just wasn’t worth it. If you are looking to get to flint rock for the overlook just take the flint mill trail instead.
