Camp Olmsted is a summer camp and retreat in Cornwall-on-Hudson, New York, operated by the Five Points Mission, a Methodist organization. It is located along Bayview Avenue, NY 218, near Storm King Mountain. It was founded in 1901 when the mission, which had been working to improve conditions for residents of the eponymous Manhattan slum (depicted in the Martin Scorsese film Gangs of New York) since 1848. At the turn of the century, they realized children from the immigrant families they were helping needed a place to get away from the city during the summer. Sarah and John Olmsted donated the 21-acre (8 ha) parcel that was originally known as the Olmsted Fresh Air Home. Campers would take the Hudson River Day Liner from the city to Cornwall and then proceed to the camp.In 1966 the New York City Society took a role in operating the camp, which, when three cabins were winterized, allowed for year-round operation. The camp was added to the National Register of Historic Places in 1982, and accredited by the American Camp Association two years later. The addition of two adjoining properties in 1998 brought the facility to its current 76-acre (30 ha) size. Today the camp runs four 12-day sessions for city children in the summer, and religious retreats year-round.

Its distinctive curved ridge is the most prominent aspect of the view south down Newburgh Bay, from Newburgh, Beacon, and the Newburgh-Beacon Bridge. It can also be seen by southbound travelers on nearby sections of the New York State Thruway. This view was a popular subject for early artists of the Hudson River School. While thought of as the highest point in the area, its summit reaching approximately 1,340 feet (410 m) above sea level, the eastern summit known officially as Butter Hill is actually higher, with an elevation of 1,380 feet (420 m).

The Amelia Barr House, also known as Cherry Croft, is located on Mountain Road in Cornwall on Hudson, a village in Orange County, New York, United States. It is on the slopes of Storm King Mountain, near Storm King School. Barr, the most published American female writer born in the 19th century, lived here during the most prolific and successful period of her career. Barr, an Englishwoman who came to the United States from Lancashire at the age of 19, moved to New York City in the early 1870s with her daughters from Galveston, Texas, after her husband and six of her nine children died of yellow fever. There she began to write fiction. In 1885, she and her daughters began spending summers at a boardinghouse in Cornwall. Her novels eventually became successful enough that, in 1891, she could afford to buy the cottage, previously rented by artist Abbot Handerson Thayer. After highly regarded local builders Mead and Taft renovated it extensively, she renamed it Cherry Croft, and accordingly most of her work from that time period came to be known as the Cherry Croft novels. She summered there until selling it in 1915, when she moved to White Plains to be cared for by her daughter Lilly. Mead and White's renovations resulted in a 3,500-square foot (315 m2) three-storey home with six bedrooms, four bathrooms, library, living room and dining room. It has a 1,000-square foot (90 m2) wraparound porch. Barr had a turreted writing room added on upstairs for her use. The original fixtures and trim, including the window screens, are still in place. In 1982, it was added to the National Register of Historic Places. It has been repainted in white and black from the brown with red trim Barr favored. After continuous occupation since Barr's day, in April 2006 it became vacant, and remains so, although work is actively being done on the house as of 2007.

At 15.5 miles (25 km) in length from its source at the confluence of Cromline Creek and Otter Kill west of Washingtonville, it is the longest stream located entirely within the county. Despite its small size relative to the Hudson, it has been a major influence on the topography of eastern central Orange County. Its 187.2-square-mile (485 km2) watershed, including not only both its parent streams but Woodbury Creek as well, reaches as far inland as Warwick as well as 21 other area communities. Near Salisbury Mills it is crossed by the Moodna Viaduct, the longest actively used railroad trestle east of the Mississippi.
