How to fit them into 4 half-days

Grouped by area and kept to about four hours each, so you walk more than you ride.

  • Half-day 1 (Bo Hon Island, Dau Go Island and Central Ha Long Bay): Sung Sot Cave → Luon Cave kayaking → Thien Cung Cave → Cua Van fishing village, at least 4 hours.
  • Half-day 2 (Lan Ha Bay): Lan Ha Bay by kayak and boat, at least 6 hours.
  • Half-day 3 (Cat Ba Island): Cat Ba National Park, at least 2 hours.
  • Half-day 4 (Van Don and Bai Tu Long Bay): Bai Tu Long Bay, at least 6 hours.

The best months to be outside

  • December: highs of 22°C (72°F), about 4 rainy days, moderate crowds. Cool and dry with clear days mixed with grey ones; evenings on deck need a jacket.
  • November: highs of 25°C (77°F), about 5 rainy days, moderate crowds. Dry and pleasantly mild with good visibility; a strong month for cruises and hiking on Cat Ba.
  • January: highs of 20°C (68°F), about 6 rainy days, quiet crowds. Cool, grey and dry, with misty views that some find atmospheric; swimming is too cold for most visitors.
