A Wooded Walk to a Natural Tunnel

Four miles into the woods, the reward is a natural tunnel: a short, cave-like passage with an opening at each end and daylight visible all the way through. It is more of a dramatic interruption in the landscape than a deep-cave expedition, and walking through it gives the longer hike a satisfying destination.

The approach is not just a march toward one landmark. The route moves through a peaceful mix of tree cover, creek corridors and bluffs, with enough changes in terrain and scenery to make the miles feel like a proper outing rather than a simple walk in the woods.

There is a useful range of outings here. Savanna Ridge is the quick option, a short and easy nature-minded loop that can be finished in under an hour. It works well for a brief stop, a slower look at the landscape, or a day when an eight-mile commitment is not on the agenda.

The tunnel trip is the longer choice. Posted trail information places the tunnel at about four miles from the trailhead, and the return makes for roughly eight miles or a little more. Plan on about three and a half to four and a half hours for the full hike, depending on pace and time spent around the tunnel.

Eastside is generally the friendlier route: flatter, wider and better suited to a leisurely walk. Westside is narrower, hillier and rockier, making it the route for hikers who do not mind paying closer attention to their feet.

Much of the trail is fairly flat or gently rolling, especially on the easier stretches, but it does not stay uniform. Creekside sections bring water close to the route, while bluffs give the woods a more rugged edge and create a pleasant change from the forest floor.

Shade from the trees covers much of the hike, a welcome feature on a long walk. The woods can still feel warm in mild weather, particularly when the trail is busy and the day is more hike than stroll, so water belongs in the pack for the tunnel outing.

Water crossings recur on the longer route. Some streams can be forded by stepping from stone to stone, which adds a little old-fashioned trail business to the day and is a fine reason not to wear shoes meant only for dry sidewalks.

This is not uniformly smooth walking. Loose rocks, uneven ground, hills and stream crossings appear along the longer routes, and the East fork in particular has medium-sized loose rocks that demand more care than the flatter portions of trail.

Sturdy footwear makes practical sense here, especially if the plan includes the tunnel rather than only Savanna Ridge. The terrain asks for steady steps in places, and loose rock and occasional rockfall concerns are worth taking seriously.

The main trails are generally marked and maintained, with clear signage at the trailhead. Side trails and connections can be less obvious or less well maintained, so the posted route is the one to follow closely rather than treating every path in the woods as interchangeable.

The tunnel has an uncomplicated appeal for families: after a substantial wooded approach, there is an actual passage to enter, walk through and emerge from on the other side. Children in particular tend to enjoy that moment of reaching the destination and going through it.

Because light remains visible through the passage, it does not carry the commitment or uncertainty of entering a dark cave. It is a brief, tangible bit of geology in the middle of a hike—interesting enough to linger over, but simple enough that the trail itself remains the larger adventure.

A free parking lot has plenty of space, with a designated area for trailers. That makes the trailhead a straightforward starting point for a short loop, a long out-and-back, or a run through the wooded sections.

The routes see hikers, walkers, runners and dog walkers, and the variety of trail lengths helps explain the mixed use. Someone can take the easy Savanna Ridge loop while another member of the group sets out for the more substantial tunnel hike.

Ticks have been reported in the area, so tick precautions are worth building into a day in the woods. The long tunnel route also calls for plenty of water, footwear that can handle wet or rocky ground, and enough time not to rush the return.

The destination can be popular during the week, but its multiple routes spread the experience across different kinds of outings. A short shaded loop and a multi-hour hike to a light-filled natural passage are both on the same menu.
