As winter set in, it's the perfect time to get out of town and escape the seasonal mood disorder. Here are vacation ideas to adopt now.

Costa Rica

Costa Rica, located in the Valle del General, is an off-the-radar agriculture town that's not overrun with tourists. The area is known for its coffee, pineapples and sugar cane plantations, as well as its rich forests. What's more, you can enjoy horseback riding, spend afternoons at the spa or tour a nearby wildlife shelter to look out for colorful birds, sloths and other animals.

Los Cabos, Mexico

If you love wine, travel to Los Cabos, a beautiful vacation destination at the southern edge of the Baja Peninsula. During your getaway, you can enjoy special wine tastings and dinner cooked by Los Cabos's Michelin-starred chef. There are wildlife-viewing opportunities, too. From December through May, you can spot whales, manta rays and more wildlife.

Petit St Vincent, the Grenadines

This private Caribbean island was spared the anger of hurricanes Irma and Maria. What's more, the whole island is only 115 acres and has 22 cottages. Each cottage is located in a quiet place, and you can expect to unplug and recharge phones with no wireless connections, televisions or telephones in the cottages. Even better, you can spend your days admiring fascinating marine (海洋的) life at the Jean-Michel Cousteau Diving Caribbean center.
