Popular locations for visit:
I have visited the following things(http://icwow.blogspot.com/search/label/pabna) from this district. Also there are other things available which I couldn't able to visit for lack of time. You can give a try on those.
Where to Stay:
I have stayed at Ishwardi(ঈশ্বরদী) town during my travel. It is very rare to see any town in Bangladesh that keeps alive till long night. You'll see lot of activities at that town even if it is 2:00 at night. Possibly the reason is having a large railway station inside the town. I have stayed at the Hotel Sajid(হোটেল সাজিদ) which is just beside the rail station. But there are other hotels which are having better quality than mine. Just have a walk around the town, and you'll find plenty of hotels. Our hotel rooms cost 100, 150 and 200 taka.
How to reach:
You can reach into Pabna(পাবনা) by using both Rail and Bus service. The southern-west portion of the Bangladesh is connected by rail through this district. Bus fare is around 400 taka. I don't know the train fare, but the trains are very good in service.
