Tunnel Trail

Q: Can I hike this with kids under 8?

Yes. Short distance and shade are kid-friendly. Rooty terrain and low overhangs require close supervision, but most kids handle it fine with good shoes.

Q: Why are the tunnels closed?

Safety concerns. NPS didn't specify details, but the closure is indefinite. Come for the forest and cool rock walls instead.

Q: Will I slip on this wet trail?

Possibly. The earth is perpetually moist, and recent rain makes it treacherous. Wear shoes with aggressive grip. Move deliberately on roots.

Q: Do I need a detailed map?

Not strictly—the trail is well-marked as path (7) on the Grandview Area Trails map. Grab the map at the visitor center to understand the two endpoints and plan your exit.

Q: How long does this actually take?

20-30 minutes if you move steadily. 45 minutes if you pause for photos and linger in the cool spots. Time expands in good shade and cool rock.

Overview

About This Trail

This is Grandview's shortest trail—a half-mile shaded forest passage through tunnels in sandstone and beneath a massive rock overhang. Don't come for the hike; come to escape the heat. Moist earth, lush vegetation, and cold-to-the-touch rock deliver a sensory reset in 30 minutes. Critical caveat: the tunnels are currently closed for safety, but the shaded forest and overhanging stone remain open.

Moderate

Trail Highlights

The closed tunnels and massive rock overhang are the intended draws. Even with tunnels off-limits, the shaded forest and cold-to-touch sandstone walls deliver a physical and psychological cool-down on scorching days.

Insider Tips

• The two trailhead endpoints (Main Overlook walkway vs. baseball diamond area) create a natural one-way option—park at one end, walk through, exit the other • Bring the Grandview Area Trails map (available at visitor center); it clarifies the two starts • The real payoff isn't the tunnels—it's the mist and cold sandstone walls on a 90°F day

Best Season to Hike

Spring through fall; summer maximizes heat-escape value

Hiking Tips

Carry 1-2L water minimum—the shade masks dehydration risk; you'll forget to drink until you're parched
Wear traction shoes; rooty terrain and perpetually damp earth create slip hazards
Pack a microfiber towel; moist conditions are year-round
Start before 9am on weekends to dodge family-outing crowds
Watch headroom under rock overhangs and passage walls—crouch if needed

Family Info

Short distance and full shade make this attractive for kids. Rooty terrain and rock overhang passages require close supervision. Most families with school-age children handle it well; not ideal for toddlers.

What Hikers Say

Hikers praise this trail as a tactical heat-escape tool for blisteringly hot days. The tunnel closure is a significant letdown, but the shaded forest and cool rock still deliver. Families value the short distance; serious hikers use it as a warm-up.

FAQs

Is this trail too easy?

Yes, if you want a cardiovascular workout. No, if you want a shaded refuge and sensory escape. Don't measure by distance—measure by the microclimate. This is tactical heat management, not cardio.
