Take the CTA Blue Line from Jefferson Park and exit downtown at State Lake. Proceed upstairs and transfer to the Orange Line. The Orange Line circles downtown, so from that location it only proceeds south, so there is no issue about getting on in the wrong direction. Exit at Roosevelt Road, then walk east a couple blocks to the lakefront Museum Campus.
Jefferson El will take you straight Down town get off at Merchandise Mart . Transfer to the Michigan Ave. bus to Navy Pier terminal get on the shuttle bus going toward Planetarium and Museum area you might have to walk a couple of blocks you,ll be right there. Remember the bus you take so when you go home your not lost have fun.
