This well-established but smaller tour company schedules tours only when a minimum number of people sign up (if they don’t hit the minimum, you may have to switch to a different tour). The upside is you’ll get more personalized attention, and van tours are maxed out at 13 people. Isabelle’s tours (available in English and French) include: New Orleans city overview; plantations; swamps and airboats; and good combination tours—like a 3 1/2-hour City Overview and Katrina Recovery tour; or the City and Estate tour which adds Longue Vue House and Gardens to a tour of the French Quarter, St. Louis Cemetery No. 3, Bayou St. John, Lake Pontchartrain, and the Uptown and Downtown neighborhoods—a very extensive overview tour with a broad reach. Isabelle also offers swamp and plantation tours, but no Garden District or walking tours.
