I visited this archaeological site by private car from Lahore, it is 200km or about 4 hours to drive. The Harappans used the same type of bricks as in its sister city of Mohenjo-daro, but this more famous WHS site was unfortunately closed due to the recent flooding in Southern Pakistan.

Hidden under layers of mud and soil lies one of the most sophisticated towns of the third millennium BC. Excavations were carried out from 1872-1995, and parts of the objects are now displayed in the on-site museum, and in the Lahore museum. There is a big range of animal&bird figurines made out of terracotta. Rhinoceros, a humped bull, and the mythical unicorn are plentiful, and they were also incorporated in the manufacturing of seals. The museum should be visited first, then the trail around the mounds. There I learnt that at the North end of Mound AB even a earlier Ravi Hakra Phase of civilization (3900-2800 BC) was discovered. 

A Terracotta chess board has been found as well, it might be the oldest one ever excavated anywhere!

I paid a small entrance fee, and a security guard accompanied me by motorbike, the path is paved, but it was really hot on that day.
