Along with Allentown and Bethlehem, Easton is one of three primary cities that comprise the Lehigh Valley, the state's third most populous metropolitan area. Easton is the easternmost city of the Lehigh Valley, sitting on the confluence of the Delaware River (which separates Pennsylvania from New Jersey) and the Lehigh River, for which the Lehigh Valley is named. Easton is the smallest of the three Lehigh Valley cities, with approximately one-fourth of the population of the largest Lehigh Valley city, Allentown.
Easton is almost equidistant from Philadelphia, which is 60 miles (100 km) to the south, and New York City, which is 70 miles (110 km) to the east.
Air transport to and from Easton is available through Lehigh Valley International Airport, which is located approximately 15 miles (24 km) west of the city, in Hanover Township.
The city is split up into four primary sections: Historic Downtown, which lies directly to the north of the Lehigh River, to the west of the Delaware River, continuing west to Sixth Street; The West Ward, which lies between Sixth and Fifteenth Streets; The South Side, which lies south of the Lehigh River; and College Hill, a neighborhood on the hills to the north which is the home of Lafayette College. The boroughs of Wilson, West Easton, and Glendon are also directly adjacent to the city; the first and largest of which, Wilson, partially aligns in the same North-South Grid as the city of Easton.
The greater Easton area consists of the city itself, three townships (Forks, Palmer, and Williams) and three boroughs (Glendon, West Easton, and Wilson).
