Tabas is a desert city that experiences scorching summers and mild winters. Because of its climate many people guess the city’s name comes from the Persian word “Tab” meaning “hot” or “feverish.” The history of the city is believed to date back to the Sassanid era. Halvan Cave and Halvan Desert with their beauties are among the natural attractions of Tabas. Halvan Cave is about 160 million years old and is related to the middle Jurassic period. It is located in 75 km northwest of Tabas and attracts many avid tourists every year. There is no detailed information about the length of this cave.
