If debating between a trolley tour and a walking tour, pick Savannah Belle Walking Tour. In the 1.5-hours you have Michelle's undivided attention, wealth of knowledge and you can take time to get those pictures in (instead of whizzing by them if you were on a trolley). It's only a mile of strolling through historic Savannah and she tries to choose shaded areas when sharing her tidbits on architecture, war stories, the legends and tales of the people who made the area famous. She truly loves her town and she knows all the good places to grab a bite. Ask her anything... she's accommodating and knows her stuff. There's no way we would learn this stuff from reading a monument or historic marker. I like her saying about the day's weather: "It's like stepping outside and feeling like your body was licked by a dog." So dress for the humidity, heat and keep hydrated. But most of all, have fun soaking in Savannah on your walk.
