Princeton, home of the prestigious Princeton University, is a Borough, surrounded by Princeton Township in Mercer County, central New Jersey, population approximately 30,000. The University's Nassau Hall served as the Capitol of the United States for a single summer in the late eighteenth century. Princeton counts among its former residents Albert Einstein and Thomas Mann.
Visitors should note that the prestigious Princeton mailing address extends far beyond the Borough and Township limits. For example, Princeton never actually touches US Route 1, however, many businesses along Route 1 sport a Princeton mailing address.
Princeton has an eponymous airport located in Montgomery, less than 2 miles from Nassau Street and Princeton University. Princeton Airport serves mostly general aviation (i.e. hobby) flying, but it also sees its fair share of business charter flights. It has one runway, fuel stations, lots of aircraft tie-down space, and hangers. This makes the airport a very cost-effective solution for travelers who pilot their own airplanes. Car-rental service is located on-site.
Other nearby airports include the Somerset Airport, Central Jersey Regional Airport, and Teterboro airport. These airports, like Princeton, do not operate commercial flights, but anyone with his/her own airplane can fly in.
The larger Trenton Mercer aiport offers some air-taxi options.
The nearest major airports are Philadelphia International (approx. 1.5 hours by car) and Newark Liberty Int'l (approx 1 hour by car).
A small rail station in close proximity to both the University campus and the downtown district provides a shuttle service, known locally as "the Dinky," to the nearby Princeton Junction train station, from which New York City, about an hour's ride to the north, and Philadelphia, Baltimore, and Washington, DC, to the south, can be accessed.
Princeton Junction station is about 4 miles southwest of the main university campus. It is served by the Northeast Corridor Line, the main commuter rail line running from Washington DC to Boston. This line is often filled during the morning and evening rush hours with commuters traveling to New York or Philadelphia.
Reaching the center of campus from the Dinky is a bit tricky. Train travelers from New York should purchase a NJ Transit Northeast Corridor line train ticket from Penn Station to Princeton (not Princeton Junction). The southbound train from Penn Station will stop at Princeton Junction; disembark there and hold on to your ticket, as you'll need it to take the shuttle train ("dinky") from Princeton Junction to Princeton. The shuttle's Princeton terminus is at the south edge of campus; to reach the center of campus (containing the Admissions Office, Nassau Hall, the University's oldest building, etc.), walk north from the station through a group of triangle-shaped buildings (I.M. Pei designed Spelman College), continue north on a road past a gymnasium (on your right) and a dormitory (on your left). This road dead-ends in a loop behind another dormitory, continue walking north until you reach an immense staircase terminating at an archway; this is the Blair Arch. Walk up the stairs and continue eastward along the path. When you reach a white marble building (Clio Hall), the admissions office (West College) will be just to the north, on your left, and Nassau Hall will be further north. A stair-free, less confusing path, is to take the same path through Spelman, but walk behind the gym to a road through the center of campus (Elm Drive), which leads north to West College and Nassau Hall. Visitors may wish to visit the Frist Campus Center for a campus tour. Tours depart from the Welcome Desk on the main floor of the Campus Center (take the stairs down, not up, at the front of the building). To get to Frist from the Dinky Station, the least confusing (albeit far from the shortest) path is to take Elm Drive until one reaches an east-west path running behind a white marble building. Make a right (east) on this path, and walk until you reach a major street (Washington Road). Don't cross Washington; just turn right (south), and continue until you reach the Campus Center, which is easily recognizable by "Fristhenge", a thin brickcourse supported by pillars in front of the building. (Preferably, one would continue north on Elm Drive and ask for a map at West College.)
COACH USA (under the name Suburban) offers bus service from New York and New Brunswick to Princeton.
New Jersey Transit operates several commuter bus lines connecting Princeton with other areas. Several bus stops are located throughout Princeton Borough and Township. Buses generally leave on every half-hour between 8.30 am and 9 pm weekdays, and irregularly before and after those hours. The Saturday schedule is similar, and the Sunday schedule is hourly.
Routes 206 and 517 run through Princeton. The main street is Nassau Street, on which the majority of shops and eateries can be found. Although Princeton has parallel parking spaces along the main roads, most are metered and all are checked frequently by the infamously vigilant local parking patrol. The Princeton Parking Cash Card, available from machines in Spring Street Garage, conveniently pays for parking at all meters and allows for the reclamation of unused "time" upon return to the meter; "max out" the meter then take back unused credit upon return to forfend the award of parking tickets in the forty dollar range. There are multiple parking garages; the municipal garage on Spring Street, a few dozen feet from the Princeton Record Exchange, is the most affordable, but the pricier garages in Palmer Square and on Chambers Street are convenient to many locations as well. Infrequent visitors must note with dismay that Sunday parking on the street is no longer free.
Everything in the downtown area is easily accessible on foot from the main parts of the campus or the two hotels in town. A physically fit visitor can reach any part of town with a bicycle. The only public transit is a single bus line that makes a leisurely loop around the outer parts of the town. Taxis are easily available by cell phone, or at the taxi stand on Nassau St and Witherspoon.
The University Campus, with many attractive buildings in "Collegiate Gothic" style as well as colonial-era Nassau Hall (the temporary capitol of the United States for a summer) and the strikingly modern Woodrow Wilson School building. Don't miss the the stately University Chapel with it stained glass and stone arches. The Princeton library has spectacular exhibits and standing collections you can get up close and personal. The Princeton University Art Museum also features an impressive collection of works by an array of well known and highly touted artists from throughout history. College tours start at the Frist College Center building; check website for times.
The Fountain of Freedom, outside the white marble-columned Woodrow Wilson School building. The fountain is surrounded by a large pool. The pool is less than 2 feet deep, and there will often be children playing in the fountain. It is also a tradition for the University's marching band to play while standing in the fountain after Princeton football victories.
The Princeton Public Library, corner of Wiggins and Witherspoon. The library has been at this location since the 1970s, but recently rebuilt a state-of-the-art facility. They offer free Internet access to all if you need to check email or print a ticket. Their wireless network reaches out to the plaza for 24/7 access. Near many cafes and less than a quarter mile from Palmer Square.
19th century mansions on Library Place, Elm Street, and nearby.
Small historical house museum at Bambridge House on Nassau Street.
Albert Einstein's house, 112 Mercer Road. At his request there is no marker but it is the small, white, ordinary home located across Mercer Road from a small park. You can see it best on foot as Mercer is busy and there is nowhere to pull over. From Nassau Street, bear left onto Mercer. Walk past elegant row houses and a large church and continue past the campus of the Princeton Theological Seminary. At the bottom of the hill on the left side of the road, small homes front onto the road directly above the sidewalk. The second one you encounter was Einstein's.
The picturesque, 18th century Nassau Inn in Palmer Square is worth visiting even for those not wealthy enough to book a room there.

Carnegie Lake, a manmade lake financed by 19th century steel magnate Andrew Carnegie. It is located just south of the main university campus and roughly 1 mile from Palmer Square. It is extraordinarily picturesque. The University's nationally-ranked crew team practices here, and it offers boating (no gas motors), canoeing, fishing, and, in the winter, ice skating.
Princeton Battlefield, a healthy walk from the center of town along Mercer Road through a prosperous residential neighborhood. Site of an engagement in the Revoutionary War as Continental troops followed up their victory at Trenton by pursuing the retreating enemy. A memorial on the field incorporates imposing columns from the mansion of Richard Stockton, an area resident who signed the Declaration of Independence before renouncing the Revolutionary cause. Every other year the Battle of Princeton, the second George Washington ever won, is re-created at the site complete with firing cannons, men on horseback and charging troops. Dress warmly.
Continue away from town on Mercer Street to see the striking 18th century Quaker Meeting House (ironically adjoining the battlefield), with its simple cemetery, and the 200-year old stone bridge, still in use, across peaceful Stony Brook.
The towpath between manmade Carnegie Lake (the University asked for a stadium but Andrew Carnegie gave them a lake for the more gentlemanly sport of rowing crew) and the early-19th C Delaware and Raritan Canal (D&R) passed numerous original canal locks and other historic structures. The towpath runs for many miles between the Raritan River in New Brunswick to the Delaware River at Trenton. Look for canoe and kayak rentals at Princeton, Griggstown and other locations. If you picnic, watch for poison ivy which abounds along the banks of the canal but also be on the lookout for Great Blue Heron, turtles and deer.
