Paris

Paris hosted the 2024 Summer Olympics, completing a 15-billion-euro infrastructure overhaul that cleaned the Seine for the first time in a century, added 100km of new cycling lanes, and restored major monuments including Notre-Dame Cathedral, which reopened in December 2024 after a five-year reconstruction. The city receives 44 million tourists per year -- the most of any city on Earth -- yet the 2026 post-Olympics window offers unusually uncrowded museums and hotels at competitive rates.
