Skyline Drive, Virginia

Skyline Drive runs 105 miles along the crest of the Blue Ridge through Shenandoah National Park, with seventy-five overlooks and a speed limit of 35 miles an hour. That last number is the one that matters for planning: end to end without stopping takes about three hours, and no group has ever driven Skyline Drive without stopping. A charter bus on Skyline Drive turns a long, winding day into the easiest kind of sightseeing there is.

The height limit that decides your vehicle

Mary's Rock Tunnel, near Thornton Gap, has a clearance of 12 feet 8 inches. Anything taller cannot pass, and that includes a good number of full-size coaches. This is the single most important fact about running a bus on Skyline Drive and it is not negotiable — the tunnel is cut through solid rock.

It sits at roughly mile 32, between the Front Royal and Thornton Gap entrances. A group traveling the northern section either uses a vehicle that clears it or plans an itinerary that starts south of it. Confirm the actual height of the assigned vehicle rather than the model's nominal spec, and confirm it before you build the route.

Commercial tours in the park also require the appropriate National Park Service authorisation. A legitimate operator will have it; ask.

Four entrances, and which one to use

• Front Royal, mile 0: the northern end, closest to Washington and the busiest on autumn weekends.
• Thornton Gap, mile 31: reached from Luray, and the natural entrance for a group basing near the caverns.
• Swift Run Gap, mile 65: from Elkton and Charlottesville, and the best access to the central section.
• Rockfish Gap, mile 105: the southern end, where Skyline Drive becomes the Blue Ridge Parkway. Nearest Waynesboro and Staunton.

Entering at one end and exiting at another is the sensible plan for a group. Driving in and back out doubles the time for the same scenery.

The stops worth building the day around

• Big Meadows, mile 51: the park's center, with a visitor center, a lodge, dining and the largest open meadow on the ridge. Deer are close to guaranteed.
• Skyland, mile 41: the highest point on the drive at 3,680 feet, with a dining room and the trailhead for Stony Man.
• Dark Hollow Falls, mile 50: a seventy-foot waterfall reached by a steep 1.4-mile round trip. Popular, and harder coming back up than going down.
• Hawksbill and Stony Man: the two highest summits, both reachable on short hikes with genuinely large views.
• The overlooks themselves: many are simply pull-ins, and the larger ones take coaches while the smaller ones do not.

Which charter bus suits the drive

• Twenty to thirty-two: a mini bus is the most flexible vehicle on this road — it clears the tunnel comfortably and fits the smaller overlooks.
• Forty to fifty-six: a full-size charter bus is comfortable for the approach and fine on the main road, subject to the tunnel clearance. Plan stops at the larger overlooks.
• Ten to fourteen: a sprinter van suits a photography group working the light at dawn and dusk.

There is an entrance fee charged per vehicle, which for a group is one of the rare cases where a coach is dramatically cheaper than cars — one fee instead of a dozen.
