Morsum is located close to the scientifically important geotope Morsum-Kliff [de] and to the beginning of the Hindenburgdamm linking Sylt with the mainland.

[1]: 257 Morsum is a Ringdorf [de] located on the Wadden Sea side of the island of Sylt.

Morsum is located at the transition between higher lying geest and the low-lying marshes that, until the Nössedeich was constructed in 1936/37, were constantly threatened with flooding.

[1]: 257 The Romanesque church St. Martin [de] is located a bit outside of the village centre on a slight elevation in the marshes.

It was built in the early 13th century and thus, with St. Severin at Keitum, is one of the oldest surviving church buildings on Sylt.

In the 1930s, the Nazi government took an interest in the local iron ore deposits, but by the beginning of World War II no thorough prospection and evaluation had taken place.

Another attempt was undertaken during the 1950s, when businesses were looking for a supply of rare ores such as titanium for the resurgent German economy.

[1]: 258 Currently, the Kliff is threatened by erosion made worse by visitors or fossil hunters leaving the designated paths.

In addition, the only extant burial mound on Sylt dating from the Viking Age is located on Morsum's territory.

Sylter Verkehrsgesellschaft [de] operates buses that provide public transport on the island.

The public broadcaster NDR operates an 80-metre radio antenna (Sender Morsum [de]) outside of the village.
