De Kaag lies on an island, Kagereiland, in a lake system called the Kaag Lakes (Kagerplassen). To reach De Kaag, a ferry is taken from Buitenkaag.

De Kaag is also part of an area called the Duin- en Bollenstreek ("Dune and Bulb Region").

The town is conventionally referred to as "De Kaag", but the name reported on both English and Dutch maps is just "Kaag".

In 2001, the village of De Kaag had 328 inhabitants. The built-up area of the town was 0.09 km², and contained 138 residences. The larger statistical district "De Kaag" has a population of around 440.

The village is first mentioned in 1308, called "Kaghe", meaning "lands outside the dike". Until the end of the 16th century De Kaag was the largest settlement in the Alkemade area.

Nusrat Fateh Ali Khan (Punjabi: نصرت فتح علی خان (Shahmukhī)) (October 13, 1948 – August 16, 1997), a world-renowned Pakistani musician, was primarily a singer of Qawwali, the devotional music of the Sufis (a mystical tradition within Islam). Considered one of the greatest singers ever recorded, he possessed a six-octave vocal range^{[citation needed]} and could perform at a high level of intensity for several hours. Extending the 600-year old Qawwali tradition of his family, Khan is widely credited with introducing Sufi music to international audiences. He was popularly known as "Shahenshah-e-Qawwali", meaning "The King of Kings of Qawwali".

Born in Faisalabad, Pakistan, Khan had his first public performance at age of 16, at his father's chelum. He officially became the head of the family qawwali party in 1971, and was signed by Oriental Star Agencies (OSA), Birmingham, U.K., in the early 1980s. In subsequent years, Khan released movie scores and albums for various labels in Pakistan, Europe, Japan and the U.S. He engaged in collaborations and experiments with Western artists, becoming a well-known world music artist in the process. He toured extensively, performing in over 40 countries.
