According to the United States Census Bureau, the town has a total area of 135.4 km sq (52.3 square miles). 133.0 km sq (51.4 mi sq) of it is land and 2.4 km sq (0.9 mi sq) of it (1.76%) is water. The town begins on the banks of the Connecticut River and extends up into foothills, many of which provide a view of Hartford's skyline. Some major developments in the town are built entirely on relatively steep hills, such as "Minnechaug Mountain", the major residential area developed from the 70s until late 90s. Part of Glastonbury resides in an area locally called "Rattlesnake Mountain" because it has a small population of Timber Rattlesnakes. Since that area is sparsely developed and mostly in a state forest, the snakes don't pose much of a threat and incidents are rare and every known bite has been treated in time. The town boasts a small lake named Diamond Lake, which is surrounded by growing subdivisions of large homes. A couple state parks and state forests touch the town, including Gay City State Park, a popular area for hiking, horseback riding, and camping. Glastonbury borders the town and cities of East Hartford, Wethersfield, Portland, Rocky Hill,Cromwell, Marlbourogh,Hebron, Manchester, East Hampton and Bolton.
