On the bus, we met at least 10 peoples who wants to shake hands to make friends with us. They are nice peoples. At last it was a young man that brought us to the museum also to invite us to visit his house. Harappa peoples are way too friendly.
To get to Harappa is way too easy. Tourists from Lahore just have to buy a bus ticket in the main bus station to Sahiwal (4 hours). The bus only go up to Sahiwal and you will be dropped there to catch another bus on the main road. Yes you just have to stand beside the main road where the bus dropped you, to wait for bus to Harappa (another 1half hours). Please look at my Sahiwal page. This of course is a budget way, if you have plentiful money to spend. you can go ahead to hire a nice comfortable taxi to send you to anywhere you like.
These are the buses that sent us from Sahiwal to Harappa. Not that bad huh. In the bus, be expect to shake hands with many peoples.
