New York City's YMCA Camp

The camp was located in a mostly wooded area encompassing about 1,000 acres in the western part of Huguenot. It contained three lakes; each lake had its eponymous camp,- Camp Talcott, Camp McAlister, and Camp Greenkill.[2] While Camp Talcott and McAllister were summer camps,[3] the facilities at Greenkill had been winterized. Greenkill was also home to the Mary French Rockefeller Educational Center and had a large gymnasium.

During the summer, the camp was a temporary home for about 1,200 -1,400 young people each season.[1][4] For the local community, a day camp was created for the summer. In 2010, after the earthquake in Haiti, a group of Haitian children was sent to the camp to recover from the trauma.[5]

Campers were 7–16 years old and most came from NYC. A majority of campers received financial aid.[4] Activities included social interactions of camp life and provided opportunities to participate in swimming, canoeing, archery, arts and crafts, field games, hiking, and more. Campers were supported by staff members. During summer, counselors and additional staff came from many different countries.[6] After the summer, Camps Talcott and McAlister were closed, while Camp Greenkill remained open for meetings and retreats.[7]

After more than a century of operation during which time, by one estimate, more than 100,000 young people[4] experienced camp life, the YMCA of Greater New York announced its decision to sell the property in March 2021, citing overall losses in excess of $100 million due to the corona virus pandemic.[8][9] The decision came as a surprise to the Camp's Board of Managers who were not consulted.[1] Former campers, staff members, and alumni rallied to save the camp.[10][11]

In August 2021, it was announced that the Wend Collective had bought the camp with the intent to reach out to "the communities that historically attended the camps, the communities in which the camps are located, and the broader youth camp sector" and to continue to serve disadvantaged youth.[12]

The camp was renamed "Camp Reimagined" and started to offer some activities in 2023.[13]
