 is bounded on the north and northeast by the Parañaque; on the east and southeast by Muntinlupa; on the south by the Imus; on the southwest and west by Bacoor; and on the northwest by the scenic Manila Bay. Half of its land area is residential and the remaining half is used for commercial, industrial and institutional purposes. The present physiography of Las Piñas consists of three zones: Manila Bay, coastal margin and Guadalupe Plateau.
The city is bisected by Real (Spanish for Royal) Street, also known as the Alabang-Zapote Road. It forms part of the Maharlika Highway which spans the whole country. The Alabang–Zapote Road connects the South Luzon Expressway which passes through Muntinlupa in the east to the Coastal Road along Manila Bay.
The Coastal Road, despite its name, is a major tollway which runs the southern length of Metro Manila's shoreline with Manila Bay. It is an important artery for people commuting to and from Las Piñas and Cavite to Manila.
In 2004, a new road called "Daang Hari" (Tagalog for King's Way) was completed in the eastern part of Las Piñas, which connects the city to the neighbouring cities of Bacoor, Cavite, Muntinlupa, and the municipality of San Pedro, Laguna allowing residents to avoid heavy traffic in the Zapote and Alabang (Muntinlupa) districts. Daang Hari is a popular route for cyclists, especially on weekends.
