Boiling Springs is a census-designated place (CDP) in South Middleton Township, Cumberland County, Pennsylvania, United States, and is part of the Harrisburg metropolitan area. The population was 3,225 at the 2010 census, up from 2,769 at the 2000 census.
Hydrogeology
Boiling Springs is located on the eastern side of South Middleton Township at , on the north side of Yellow Breeches Creek. Pennsylvania Route 174 passes through the town as 1st Street and leads northeast to Mechanicsburg and west to Shippensburg. Carlisle, the Cumberland County seat, is to the northwest via Front Street/Forge Road.
According to the United States Census Bureau, the CDP has a total area of , of which is land and , or 0.49%, is water.
Boiling Springs gets its name from the natural artesian well springs located in and around the town. Boiling Springs ranks seventh in size of springs in the Commonwealth of Pennsylvania. The largest of these springs named "the Bubble" is a 2nd magnitude spring based on its average discharge of around 0.7 cubic meters per second. About of water flows per day from a total of 30 springs dotted across approximately .
The impression of "boiling" does not result from the temperature of the water, which stays at year-round, but rather from a unique hydrogeological feature. Two vertical diabase dikes, made up of highly impermeable igneous basalt parent rock, cut through the limestone bedrock in the area and form a subterranean "V", with Boiling Springs located at the interior tip of the V.
The dikes were formed around 200 million years ago, during the late Triassic and early Jurassic periods, when Pangaea broke apart: the same period of geological activity that formed the Palisades Sill. What is now eastern North America began to separate from what is now north-western Africa. Deep faults formed in the earth's crust as the continental sections pulled apart. Magma was generated through decompression melting, and this molten rock pushed up to fill the faults. The cooler temperatures of the upper crust quickly solidified the hot rock, preventing it from reaching the surface. This geological process created large, thin, subvertical sheets of impermeable basalt, or diabase dikes.
When precipitation flows down South Mountain, a large amount of groundwater is produced. Much of the water, which has an acidic pH, is able to erode the valley's limestone bedrock and continue flowing at about below the soil. However, some of the water is trapped by the impermeable diabase dikes, which act as a hydrologic barrier. The water becomes progressively confined by the dikes as it nears the tip of the "V". Due to the positive pressure created by this confinement, water is pushed up to the surface and out of the artesian aquifer, giving the impression of "boiling" springs. The springs have a median flow of per minute. These springs, collectively known as a "spring swarm" discharge 5 to 7 times the expected infiltration given its topographic watershed. Data collected via the use of highly precise and accurate data loggers have revealed the springs hydrograph to display discharge surges, while temperature, conductivity, and turbidity remain constant. Water temperature varies seasonally by 0.3 °C but is 6 months out of phase with air temperature. A new model that has been proposed to account for these findings suggests that the excess water emanating from the springs originates from an area 60 km to the southeast on the southern side of South Mountain near the West Conewago Creek, Lat 40`04'56", long 76`43'13".

One of the most prominent springs in this area is called the "Bubble". It is located directly behind the Boiling Springs Tavern, at the intersection of 1st Street and Front Street. The name of the Boiling Springs High School mascot, "The Bubblers", was inspired by this spring.
Children's Lake
This body of water was formed by partially damming the brook fed from 30 natural springs, including the "Bubble". Children's Lake is home to many ducks, swans, and geese throughout the year. The lake dates to the 1750s when the dam was used to provide water power for iron production. In the mid-18th century, a grist mill was built by Michael Ege on the southeast shore of the lake, to provide flour and grain for the iron works. This building has been converted into apartments. On January 29, 2022, a fire occurred and caused significant damage to the mill building.
On the east shore, remaining from the pre-revolutionary iron forge complex, are the original forge and the iron master's mansion with the remnants of its terraced gardens. This 1795 Georgian structure is the most outstanding example of architecture in the Boiling Springs Historic District and of major historical significance as the home of the Ege family. The mansion is presently in a deteriorating condition and is uninhabited.
The lake feeds into Yellow Breeches Creek. A picturesque, natural stone three-arch bridge, built in 1854, stands behind the mill, spanning the creek. This limestone trout stream has developed a national reputation for fly fishing. Where Children's Lake runs into the Yellow Breeches, a one-mile stretch of water known as "The Junction" provides quality catch-and-release fishing year round. This is arguably the most intensely fished section of water in Pennsylvania when the White Mayfly hatches. Limestone bedrock streams are rich in minerals, which serve as the basis for the trout's food chain and contribute to healthy growth rates for trout.
Appalachian Trail
Boiling Springs and South Middleton Township, which are near the halfway point of the Appalachian Trail, were designated Pennsylvania's first Appalachian Trail Community. In 2010, the Appalachian Trail Conservancy started recognizing towns near the trail that are assets to hikers and the trail. As of 2012, Boiling Springs is one of 23 designated Appalachian Trail Communities. The Mid-Atlantic Regional Office of the Appalachian Trail Conservancy is located at 4 East First Street in Boiling Springs, sharing space with the Boiling Springs Appalachian Trail Information Center. As one of only four regional offices along the trail, the staff covers New York, New Jersey, Pennsylvania, Maryland, West Virginia, and Virginia south through Shenandoah National Park. It is the only Appalachian Trail Conservancy office that is located on the famous footpath itself.
Several hundred hikers pass through every week during the busy seasons. Hikers often mail themselves packages to pick up at the Boiling Springs Post Office, which is just feet from the trail. The Boiling Springs Pool offers hikers a shower for $1, and there are several bed and breakfasts, a nearby campground and even a resident who lets hikers sleep in the backyard. Nearby Allenberry Resort Inn and Playhouse rents rooms to hikers for a reasonable rate.
History
Boiling Springs was settled by Europeans prior to 1737.
The springs were partially dammed in the 1750s to provide water power for iron production, with raw materials of iron ore, timber and limestone plentiful in the neighboring mountains. The Carlisle Iron Works was in full production by the 1760s, and a grist mill was built at the end of the lake in 1762. While the foundry's iron was probably used to make ammunition and weapons for the Continental Army, no cannons were made.
Daniel Kaufman, who laid out the village of Boiling Springs in 1845, purchased from his father, Abraham, in 1843. He built his 301 Front Street home in 1880.
Kaufman and Boiling Springs played a role in the Underground Railroad. Kaufman was an Underground Railroad agent from 1835 to 1847. The Underground Railroad asked him to set up a necessary stopover between Shippensburg and Harrisburg. Kaufman provided food and transportation to fugitive slaves passing through the area; his barn and a densely wooded area nearby served as shelter. Kaufman was sued by a Maryland slave owner in 1847 and convicted in Cumberland County, but the verdict was overturned by the state Supreme Court. He was then charged in U.S. District Court in Philadelphia and convicted. He was ultimately fined $4,000 in 1852, in a case that drew wide attention.
Boiling Springs is now part of the Network to Freedom, a series of noteworthy sites along the Underground Railroad.
The area around the lake was a recreation spot as early as 1875 when a steam launch began to operate to carry picnickers down the mill race to Island Grove, on Yellow Breeches Creek. In 1895, trolley car lines were added running from Carlisle and Harrisburg. The Valley Traction Company leased the lake in 1900 and built a park as a destination for passengers on their trolleys. Boiling Springs became a resort community, with travelers coming to picnic and boat on the lake, with such park attractions as a dance pavilion, picnic pavilion, miniature steam railway and a merry-go-round. The trolley was operated until around 1930.
The Boiling Springs Historic District was added to the National Register of Historic Places in 1984.
Episode #13 of the second season of the classic TV series Route 66 was set in and filmed in Boiling Springs. The episode was titled "Burning for Burning" and was first aired on December 29, 1961.
Entertainment
Recreation continues to bring people to Boiling Springs, ranging from fly-fishing on Yellow Breeches Creek to theater, dining and lodging at Allenberry Resort, which opened in the summer of 1946. Allenberry Playhouse, whose season runs more than 40 weeks - from March to December - produced its first stage performance in 1949. The Boiling Springs Tavern, a restaurant in downtown Boiling Springs, is a popular dining destination. Parts of the tavern, which is located along an old stagecoach route, date to 1832. One of the newest eateries in town, Caffe 101, opened in 2010 in a historic building at 101 Front Street.
Boiling Springs has an annual juried arts and crafts show, called Foundry Day, on the first Saturday in June. The booths and food vendors stretch down Front Street, next to Children's Lake.
The annual Carlisle Summerfair Festival's Anything Floats event is held on the 4th of July. Teams create their own vessel and then paddle the boat from one end of Children's Lake (near the Boiling Springs Tavern) to the other end (near the Grist Mill and the Boiling Springs Pool). There is also an inner tube race. Of course, the main idea is to be the fastest boat or inner tube captain to make the trip – but most of the fun is watching to see which team is going to make it without tipping over!
The Boiling Springs Pool was built in 1927 by Gilbert Malcolm, husband of Helen Bucher. It was the first public swimming facility in Cumberland County. The pool is still open to the public today. The facility offers four pools and three waterslides. They also have a full-service snack bar and plenty of grass and shade areas.
