The municipality of Victoria has the smallest land area with 57.46 km² (22.19 sq mi).

Laguna lies on the southern shores of Laguna de Bay, the largest lake in the country.
The land near Laguna de Bay can be considered to be narrow and flat, while become more rugged going further inland towards the mountainous areas of Sierra Madre, Mount Makiling, and Mount Banahaw.

Laguna is home to 24 mountains, most of which are inactive volcanoes.
The highest peak in Laguna is Mt. Banahaw, with an elevation of 2,170 m (7,120 ft).
Banahaw, unlike most other volcanoes in Laguna, is an active complex stratovolcano, which last erupted in 1843.
Banahaw is located in the boundary of Laguna and Quezon and is home to multiple hot springs.
Laguna is also home to the Laguna Volcanic Field, which can be found near San Pablo.
The Laguna Volcanic Field is composed of over 200 dormant and monogenetic maars, crater lakes, scoria cones and stratovolcanoes, the tallest of which is Mount Makiling at 1,090 m (3,580 ft) in elevation.

San Pablo itself is known for its seven crater lakes, the largest of which is Lake Sampaloc.
Apart from the Laguna de Bay and the Seven Lakes of San Pablo, there are also two reservoir lakes that can be found in Laguna, the Lake Caliraya and Lumot Lake.
These two man-made lakes were formed by the creation of the Caliraya Dam and the Lumot Dam.

Due to its proximity to Laguna de Bay, Laguna is home to a large number of its tributaries.
One of the most famous rivers in Laguna is the Bumbungan River, also known as the Pagsanjan River, named after the town of Pagsanjan and its falls.
The Pagsanjan Falls lie at the end of the river.
The Pagsanjan Falls are a three-drop waterfall with a longest drop of 120 m (390 ft).

Laguna has 60,624 ha (606.24 km²) of alienable and disposable agricultural land, mostly found near the low-lying areas.
Around 41,253 ha (412.53 km²), or 23.44% of Laguna's total land area is forest land, situated near Mount Makiling and further south towards Quezon.
