The island was the largest island in the municipality of Sandefjord prior to the 2017 merger with Andebu and Stokke.<ref name="AG" /><ref name="RT" /><ref name="VM BB" /><ref name="BK" /> It is {{convert|900|m}} long from north to south, and {{convert|400|m}} wide at its widest from east to west.<ref name="RT" /> It is located between the Lahellefjord and the Tønsbergfjord. It is {{convert|6|km}} east of the centre of the city of Sandefjord, and immediately south of the Årø peninsula.
The island is a gated community that is connected to the mainland by a private bridge. However, there is a parking lot by the gate, which can be accessed by pedestrians. There is also a public bus route to the island (route 163). Attractions on the island include Sandbukta ("sand bay"), which is a beach on its eastern side. It is also a common destination for recreational activities such as camping, paddling, sea trout fishing, hiking, and sailing. It has surrounding views of the Tønsbergfjord and the nearby Stauper islands. A former customs station on the island, known as Blåsen, has also become a landmark.<ref name="MR" /> The island hosts annual summer camps for the Queer Youth Festival and the YWCA-YMCA Guides and Scouts of Norway.<ref>{{Cite book |last=Trygsland |first=Sindre |url=https://www.sb.no/nyheter/nyheter/skeiv-leir-for-170-unge/s/2-2.428-1.8518853 |title=Skeiv leir for 170 unge |date=2014-07-23 |publisher=Sandefjords Blad |language=no |accessdate=2021-09-03}}</ref>
==Etymology== thumb|left|Natholmen in 1947. The name Natholmen ("night islet") derives from the older days when the island was used overnight for local fishermen.<ref name="VM BB" />{{rp|97}}<ref name="MR" /><ref name="VM SB" /> One theory of the name’s origin is that fishermen stayed here overnight, hence the island was named nattholmen or "night islet". This theory is however unlikely to be true. Another theory is that the word “Nat” derives from nate (soak, wet).<ref name="RD" />
The island was named "Hnatholmanom" in written sources from 1398, while the oldest written form of the name was Knattholminn, which derives from "knottr", meaning rock ("fjellknatte") and "holmi", which means islet. In words beginning with 'kn', the pronunciation of the letter k often disappears. In 1723, the island was named Knattholminn.<ref name="RD" />
Since 1977, Natholmen has also been the name of the road that connects the island to the mainland. Natholmen is also the name of a {{convert|100|m2|adj=on}} artificial lake on the island, which was formerly used as a reservoir.<ref name="RD" />
==History== thumb|left|Main road at Natholmen. The island was often visited by foreigners, particularly Dutch, who purchased lumber in the 1600s.<ref name="RD" /> Until World War II, there were four or five families living on the island. In the early 1600s, the island was a loading site for Dutch ships that arrived to purchase lumber. In 1758, Rasmus Hanssøn, the great grandfather of Christen Christensen, moved to the island.<ref name="VM BB" />
The scouting organization YWCA-YMCA Guides and Scouts of Norway ({{langx|no|KFUK-KFUM}}) utilized a cabin owned by the Norwegian Boy Scout Organization for their first summer camp in 1916. This cabin was located by the Mefjorden and was the beginning of an annual camping tradition for the YWCA-YMCA. In 1921, the board established a committee to find and suggest an appropriate permanent campground. On 18 May 1923 the board met on Natholmen Island after hearing of a farm for sale on the island. The organization purchased the farm and opened the campground "Knattholmen Leirsted & Kystleirskole" in August of the same year.<ref name="BK" />
The first bridge to the mainland was built in the early 1920s when an inhabitant on the island had purchased a Ford Model T. The original lumber bridge was replaced by a stone bridge in 1928.<ref name="RD" />
