Nangka River runs through the north slicing between Marikina and San Mateo, while the small waterway called Sapang Baho Creek slicing the southeast between Marikina and Cainta and Antipolo.
The total land area of Marikina is approximately 21.5 km2 (2,150 ha; 5,300 acres). This represents about 3.42% of the total land area of Metro Manila.

Loyola Grand Villas and Trevi Executive Village, located at the northwest portion of the city, are gated communities with upper-middle class and wealthy residents. Barangay Santa Elena represents a poblacion, or the center of Marikina. At present, it is 38% residential, 19% commercial and industrial, 17% Roads, 8% Mixed-use, 18% for parks and open spaces, development areas, institutional, cemeteries and others.Located along the eastern border of Metro Manila, it is bordered on the west by Quezon City, to the south by Pasig and Cainta, Rizal, to the north by San Mateo, Rizal and to the east by Antipolo, the capital of Rizal province. It is approximately 21 kilometers (13 mi) away from Manila and lies within 14°38′24″N 121°5′50″E.
From the north, Marikina occupies most of the south bank of Nangka River. The east slices at the foot of the Sierra Madre mountains of Antipolo and sliced by the streets of La Milagrosa Village and Empress 1 Subdivision of Barangay Marikina Heights and Rancho Estate 2 in Barangay Concepcion Dos. A huge hilly lot within streets of Tanguile and Champaca in Marikina Heights proof that the portion is part of Sierra Madre Mountain range. The southeast slices by Sapang Baho River occupies the north-west bank. The south portion is sliced by Marcos Highway and occupies most of the north side of the highway and extends to the west until it occupies the Line 2 Santolan Station depot until it reaches the Marikina River. The east occupies the southernmost of Quezon City hills which lies in Barangay Industrial Valley and sliced by C5 Road occupies the west side until it reaches Ateneo de Manila University campus. The east part of the campus covers the city, extending to the north and sliced by several roads of Loyola Grand Villas, which covers the east part of the village until it reaches Marikina River and its tributary Nangka River to the north.
Marikina River runs to the western part of the city and surrounded by many lush trees in the Marikina River Park on the riverbanks. The south portion of the river is surrounded by structures and concrete walkways. The river covers an area of around 220 hectares (540 acres) and measures about 11 kilometers (6.8 mi) in length and is the principal drainage system for Marikina. Its depth measures from 12 meters up to 18 meters during the heavy downpour. Rehabilitation of the River started in 1992. The river traverses 11 city barangays which have streets and alleys going to the river, making river parks easily accessible. River parks today are popular sports and recreational centers not only in Metro Manila but throughout the Philippines.
Marikina is also prone to various natural disasters, including the major floodings during the onslaught of Typhoon Unsang in 1988, Typhoon Ondoy in 2009, Tropical Storm Falcon and Typhoon Pedring in 2011, seasonal southwest monsoon in 2012 and 2016, and Typhoon Ulysses in 2020. Primarily, flooding within Marikina is caused by the increase of water level in major rivers and its tributaries from the Sierra Madre mountains, followed by overflowing from its riverbanks to low-lying areas throughout the city.
Another major threat is fault lines in Marikina caused by earthquakes. West Valley Fault Line, previously known as Marikina Fault Line, lies at the west Marikina.
