40 of 155 destinations are in a prime month for at least one activity in December. Below, the highest-scoring places for each activity — on conditions alone. Crowds and hazards are shown on each destination’s page, never averaged in.
Most places have one or two months that are genuinely better — and a booking moment that comes a lot earlier than the trip. I’ll write when one of those is coming up. No schedule, no filler.
