Dalmeny is a mainly residential area, with the town built upon headlands looking over the Tasman Sea to the south, and the shore of Lake Mumumga, a coastal lagoon, to the north. Due to its location, Dalmeny is a reasonably popular camping area, with a large camping ground located in the centre of town overlooking the southern end of Brou Beach (commonly called Dalmeny Beach, despite this technically being the next beach south). Despite the town's small and mainly residential nature, the town has a small shopping district in the centre of town, an industrial area to its north-west, and two retirement and aged-care facilities, as well as a bowling club with four greens and a small restaurant.
There are many walking and cycling paths through Dalmeny, some along the coastline. Bushwalking is possible in some areas of the Eurobodalla National Park. Dalmeny also has many public boat ramps, picnic spots and lookouts and functional sporting fields.
There are two roads which lead into Dalmeny. Mort Avenue leads from the Princes Highway, and Dalmeny Drive leads from Kianga. Both these roads make up Tourist Drive 5, which provides views of Dalmeny's many beaches. There are many parking spaces in Dalmeny as well, particularly around Dalmeny Beach. There are also bus routes that run through Dalmeny connecting the town with the rest of the south coast.
Dalmeny is best known for its many beaches, which stretch right around the coastline. Dalmeny (Brou) Beach is the most popular beach, which is on the northern coastline. This beach is patrolled by lifeguards during summer, and is walking distance from shops and the camping ground. Dalmeny (Brou) Beach is great for swimming, surfing and bodyboarding. Dalmeny (Brou) Beach is also part of the Eurobodalla National Park.
Yabbarra Beach is on the eastern coast of Dalmeny, and is not patrolled by lifeguards at any time. This beach is more popular with surfers, as the waves here usually stronger than Dalmeny Beach. Yabbarra Beach also has many rocks to the side of the beach, which can pose a danger during rips.
Dalmeny has a small shopping complex across from Dalmeny Beach featuring a supermarket, newsagent, cafe and a service station.
