If you’re dreaming of a white Christmas, head to Tallinn to see the medieval city decked out in a blanket of snow, complete with flickering candles lining the streets and markets flogging quintessential Christmas curiosities and festive treats. And if that’s not enough seasonal charm for you, make for Rovaniemi in Finnish Lapland, the ‘official home’ of Santa Claus. Once you’ve dropped your gift list off with the big man himself, treat yourself to a husky sledding excursion or reindeer safari to explore the region in full effect.
Interestingly, I had not seen that June travel warning. It’s hard to know what to think of it. On one hand, the US State Department has official warnings like this to many places, including quite a few that people safely travel to every day. And also, even when Colombia had its problems for all those years, Cartagena was considered safe because it’s this tourist beach town and the drug and FARC problems had nothing to do with it. My best guess is that Cartagena itself would be fine and perfectly safe, but I wouldn’t rent a car and drive around the highways myself at this point. Sadly, I think it might be best to save Cartagena for another time when there is no known threat.
Unsurprisingly, the end of December is the beginning of the peak season for resort prices, so those who are able to come earlier in the month will be getting better deals. Still, the all-inclusive resorts are locked in heavy competition all year so this area can be a great deal compared to the alternatives, even in high season. If you are looking for where to go in December for an all-inclusive beach holiday, this is your best option for most people.
Hurricane season officially ends on November 30, so it's safe to visit the Caribbean. There's good news for skiers, too, since most of the northern hemisphere is heading toward winter as the year comes to a close and mountain regions become dusted with snow. Couples who prefer a warm-weather vacation in November or December will have to travel south to find balmier temperatures — and prices begin their uphill climb toward the high season.
Trekking in Nepal during peak season might not sound like the most sensible choice for penny-pinching backpackers. But you can still enjoy the ideal weather without spending a fortune on in-demand hotels and expensive permits if you're happy to swap big-name trails, like Everest Base Camp and the Annapurna Circuit, for quieter treks to Kanchenjunga Base Camp and around the Langtang Valley. Idyllic conditions (dry but not witheringly hot) are also on offer in Rajasthan, one of India’s most vibrant and varied states. Chug between notable, attraction-rich cities like Jaipur, Jodhpur and Udaipur on an atmospheric and wallet-friendly Indian train, snacking on spicy pakoras and sipping sugary chai en route.
