Lyngdal was established as a municipality on 1 January 1838. Austad and Kvås were separated from Lyngdal on 1 January 1909 but they were again merged with Lyngdal on 1 January 1964, together with the area of Spangereid west of Lenesfjorden.
It is a coastal municipality, and borders to the southeast Lindesnes municipality, Audnedal to the northeast, Hægebostad to the north, and Kvinesdal and Farsund to the west. Lyngdal declared township on 1 January 2001.
Major sources of revenue are wood processing, agriculture, and commerce. Tourism is also central to the community, with the beaches of Kvavik and Rosfjord being popular resorts during the summer.
European route E18 goes through Lyngdal.
The nearest train station is Snartemo in Hægebostad to the north, which is about half an hour's drive away, served by a shuttle bus.
If one wishes to reach Lyngdal by car from the Continent, the ferry company Color Line operates car ferries from Denmark 2 times each day (3 times on Saturday - Monday), from Hirtshals to Kristiansand, which is about an hour's drive away.
Though Lyngdal is best enjoyed by car, some local routes are served by the bus company Sørlandsruta. There is a bus station in the centre of town.
The taxi central is located near the bus station:

Lyngdal is a commercial centre for the western part of Vest-Agder. The city centre, Alleen [dead link], contains numerous shops, while the shopping centre Alleen Senter (counter-intuitively located outside of Alleen) is, as of early 2013, in the process of a significant expansion.
Lyngdal used to be a "dry" town, but with time a few places have cropped up where alcohol is served. Lyngdal Inn and Jonas B. Gundersen above, and Rosfjord Strandhotell and Paulsens Hotell below, all serve beer. Unlike before, one can now buy beer in the stores, and there is also a Vinmonopol (Wine Monopoly).
- [dead link] Paulsens Hotell & Cafe. Reasonably new hotel, with a 19th-century atmosphere.
- Rosfjord Strandhotell. Hotel right by the beach, where there is also a camp ground.
