Garmsar is about 95 kilometres (59mi) southeast of Tehran. It lies on the edge of Dasht-e Kavir, Iran's largest desert. Many people in the city commute to Tehran due to its proximity. Ghasre Bahram, The Stone Way, Stonvand Castle, the Sar Darre Mountains, and Kavir Desert National Park are tourist attractions located in the area.

The Hablehrood river originating from Dalichai-Firouzkooh flows to the plateau of Garmsar. Its water is extensively used for agriculture. Since salt water mixes with Hablehrood before its arrival to the city, the water is not fit for drinking. Hablehrood is the only permanent river in Semnan province. Thanks to the water provided by Hablehrood, people in Garmsar grow wheat, barley, cotton and yellow melon. Garmsar is known across Iran for its sweet and crispy yellow melons.[9]
Water management
The many river branches and the irrigated fields provide recharge to the aquifer. Since ancient times, groundwater in the Garmsar area has been exploited by ghanats (qanats, karezes) and shallow wells, mainly for irrigation of agricultural land, but also for household purposes. In the last decades, the number of deep-wells has increased sharply and the ghanats have fallen dry.[10]
Yet, at the fringes of the fan, problems of waterlogging occur owing to irrigation losses higher up that are transported through the aquifer to the lower lying areas causing shallow watertables, while the evaporation from the shallow watertable brings salts into the rootzone which henceforth is salinizing. As a result, the agriculture in the fringes suffers low yields or is impossible.

Cuisine
The city has a regional variant of Tahchin, a dish made by slowly cooking marinated raw meat inside rice over a low flame for several hours.[9]
