Arlington, Virginia

The cemetery is the anchor: more than 400,000 graves on 639 acres, with the Tomb of the Unknown Soldier guarded 24/7 by the 3rd US Infantry "Old Guard." The Changing of the Guard runs every hour October through March and every 30 minutes April through September. Walk past Section 60 (post-9/11 service members) to the JFK gravesite and the eternal flame; it's a straightforward 30-minute uphill loop from the welcome center.

An outdoor memorial on the west face of the Pentagon, where American Airlines Flight 77 struck on September 11, 2001. 184 illuminated benches — one for each victim — arranged by birth year, cantilevered over reflecting pools. Open to the public around the clock and free; the interior Pentagon tour requires a separate months-ahead reservation through a member of Congress.

The 32-foot bronze of the flag-raising on Mount Suribachi, February 23, 1945. Free, always open, a 10-minute drive or Metro ride from the cemetery gate. The DC skyline across the Potomac frames the memorial at sunset; it's the photo every school group tours catalog uses.

Three stainless-steel spires rising 270 feet above the ridge south of the Pentagon, evoking the contrails of the Thunderbirds' bomb-burst maneuver. Quieter than the Marine Corps Memorial, with a panoramic view back across DC that works as a 15-minute stop on the way in or out of the cemetery.

The Greek Revival mansion on the hill above the cemetery was Robert E. Lee's home; when he left to command the Confederate Army, the Union seized the estate and began burying Civil War dead in the front yard — deliberately, so Lee could never return. The National Park Service audio guide handles the contested history (slavery, Custis and Lee family, the enslaved people who built and maintained the house) with unusual care. Budget 45 minutes.

George Washington's plantation sits 25 minutes south of the cemetery along the George Washington Parkway — technically Fairfax County, but on every DC educational travel itinerary that has a spare half-day. The mansion tour, Washington's tomb, and the slavery memorial together make a strong APUSH pairing with Arlington House; plan three hours on site.

Day-time crime around the memorial sites is essentially a non-issue; the biggest realistic risks are lost phones and separated students in large crowds at the Tomb of the Unknown. The Tour Director runs a muster check at each stop, and hotels are vetted for 24-hour reception and interior-corridor layouts.

Tap water is excellent, food safety is US-standard, no special vaccines needed beyond CDC routine. The summer heat and humidity are the real medical concern: heat exhaustion, not crime. Virginia Hospital Center is 10 minutes from the cemetery; MedStar Washington Hospital Center is across the river.

Private motorcoach for all group movement, with a credentialed, DOT-regulated driver. Students do not drive, do not scooter-share, and do not take ride-share alone. The Metro Blue and Yellow lines serve Arlington Cemetery station, Pentagon, and Crystal City directly if we swap a coach leg for the train for pedagogical reasons.

Summer severe-weather watch matters most. Tornado warnings do happen in the DC region a few times a year; our Tour Directors monitor the National Weather Service and shift indoor / outdoor timing when needed. Hurricane remnants are rare and well forecast. Winter snow can close Metro and cancel flights; build a buffer day on January and February itineraries.

Arlington House was the home of Robert E. Lee and his wife Mary Anna Custis Lee (George Washington's step-great-granddaughter). When Lee left to command Confederate forces, Union Quartermaster General Montgomery Meigs began burying Union dead in the garden specifically to make the estate uninhabitable after the war.

The Tomb of the Unknown Soldier was dedicated in 1921. The Old Guard has stood a sentinel every minute of every day since July 2, 1937 — through hurricanes, blizzards, and the pandemic. Hurricane Isabel in 2003 is the famous stress test; the sentinels stayed.

Kennedy was originally buried in a temporary plot a few yards away after his November 1963 funeral. The permanent memorial, with the eternal flame lit by Jackie Kennedy at the funeral, opened in March 1967. Robert F. Kennedy lies a short walk away, marked by a simple white cross.

6.5 million square feet of floor area, 17.5 miles of corridors, and a design target of a seven-minute walk between any two points. Built in 16 months during 1941-43 and the headquarters of every US military branch since.

The original 1791 District of Columbia was a 10-mile square spanning both sides of the Potomac. Virginia's residents petitioned to be returned to the state; Congress retroceded the southern third in 1846, which is why DC is today a truncated diamond and Arlington is a Virginia county.
