Dear Imran,  Ha ha ha.. dont be jealous,, sure you could visit some beautiful and nice places somewhere in Bangladesh.  well, except Cox'bazar… to feel the fresh green  and water, this is the right time to visit our Hill area.  You may visit Bandarban or Rangamati.. with your kids and family, you may have some soft trip to Bandarban, where you might move around by reserved vehicle to Nilgiri, chimbuk, shailo propat, buddhist temple etc.  If you are to Rangamati you may also visit some places by hired boat, which would be less hardy as your kids and family will be with you.  Thanks for your interest to visit some places of our beloved Bangladesh.
