Bateaux-Mouches

Bateaux-Mouches runs the largest glass-enclosed cruise boats on the Seine, carrying 500-1000 passengers on each vessel. The panoramic windows stretch floor to ceiling, and the covered upper deck opens completely in good weather. You'll float past Notre-Dame's flying buttresses, the Louvre's riverside facade, and under Pont Alexandre III's gilded statues while recorded commentary plays in eight languages through individual headphones.

The one-hour sightseeing cruise moves at a leisurely pace, turning around at the Eiffel Tower before heading east toward Île Saint-Louis. The boat's size means it stays stable even when crowded, but also that it feels more like public transport than an intimate experience. The dinner cruises stretch to 2.5 hours with a three-course meal served while docked, then cruising during dessert as the monuments light up.

The daytime cruises work fine for first-time visitors wanting monument identification, but the real magic happens after 8pm when the buildings illuminate. Skip the overpriced lunch cruises - the food is airplane-meal quality. The evening sightseeing departure catches the golden hour perfectly, and costs half the price of dinner cruises while offering identical views.
