This walking tour is perfect for history buffs who enjoy sipping suds, too. Spend an afternoon learning offbeat facts about the pre-Revolutionary era from your PhD-educated guide. Along the way, stop by 10 historical landmarks and three fabled taverns, where pints of ale fuel conversation that covers public whippings, cross-dressing soldiers and Samuel Adams' personal hygiene. Check online schedule for tour availability. Tickets: $59-63; must be 21 or over.
