Hanoi with its interesting architecture, vibrant Old Quarter, and rich heritage attracts a lot of visitors year-round. The best time to visit Hanoi is from September to December. It's the dry season with cooler temperatures that is perfect for hiking, sightseeing, and other outdoor activities. In autumn you can try exotic forest bitter melon and see wild blooms of cauliflower and sesame fortune flower or Lộc Vừng. Late January and February are full of festivities—Tet New Year celebrations are followed by Co Loa Citadel Festival and Tro Tram, the festival of sexuality, which is held in Phu To province not far from Hanoi.
