The village is separated into an old and a new area by the B 191 federal road which runs from Celle to Eschede and Uelzen.

The centrepiece of the old village is St Mark's Church (Markuskirche), which was built in the middle of the 14th century.

In addition there is a kindergarten in Garßen and a large hypermarket as well as several small craft shops.

Garßen is also known for its sports club, the Sportverein SV Garßen Celle, which under the short name of SVG Celle had an unbroken run since 1998 in the Women's 2nd Handball Division (North) in Germany and, in 2009, was promoted to the 1st Division.

In addition there has been a golf course on the eastern edge of the village for several years on the road to Lachendorf.
