Great way to get to Salem. Loved the place. Great witchy kitsch. Free trolley from harbour into centre is very welcome. Tourist information centre is great for getting bearings. Character actors in costume wander the street saying Good Morrow which was fun. Easy to change voucher for ticket at harbour kiosk by the Marriott hotel. Recommend café at corner of Essex and Washington St in Salem and their apple and cinnamon French toast.
Board the ferry, enjoy a beverage, arrive at destination. Trolley there at dock if needed. Close enough to walk.
It took only an hour each way to get back and forth. Great way to get to Salem and back.
