Our Thoughts and Prayers Are With the People of Nepal

In honor of Earth Day 2015, which fell right in the middle of this week's National Park Week (April 18–26), BT contributing editor Darley Newman was on hand at the Weather Channel to give our picks for some of the U.S.'s most beautiful national parks. Watch the video below! Of course, it's hard for us to play favorites, so check out our gorgeous slideshow of 15 Most Beautiful National Parks in America, and read about a few more parks that we're in awe of—and the stories behind why—at BT Staff Picks: 8 National Parks We Love!

Sure, we love the changing seasons, but the downside is that most of us live in places where summers can be too hot and winters too cold. (Still recovering from the Polar Vortex, anyone?) But there are a few select spots around the world where the weather is almost always just right. Here, four "Goldilocks" destinations to add to your bucket list: BIG ISLAND, HAWAIITemps in the 70s, with a variety of micro climates in the rain forests and mountains of this Pacific paradise What to do: Relax on a sunny, mind-blowingly colorful beach (white, black, and green sand!). Walk on an active volcano in Volcanoes National Park. Attend a traditional luau with hula dancing, roasted pig, mai tais, and Hawaiian beer.  Where to stay: Volcano Rainforest Retreat (from $180). SAN DIEGO, CALIFORNIASummer high of 76, winter low of 50, with the cool Pacific and inland desert creating a perfect oasis What to do: Spend a day in Balboa Park, home of the San Diego Museum of Art and the justly renowned San Diego Zoo. Take the ferry to Coronado and ogle the famous hotel that has hosted more than a dozen US presidents. Party Wild West style in the historic Gaslamp District. Mangia in Little Italy. Where to stay: La Pensione Hotel in Little Italy (from $140). LISBON, PORTUGAL59 in January, 83 in July thanks to the Atlantic breezes and Gulf Stream What to do: Take a walking tour that includes food and wine tasting. Stroll the majestic square Praca do Comercio. Take a day trip to beautiful Sintra, where royalty used to get away from it all. Listen to traditional fado music, an unforgettable, melancholy style of Portuguese singing. Ride the Elevador da Gloria to the top of one of Lisbon's seven hills for a great view. Where to stay: Internacional Design Hotel (from around $110) CAPE TOWN, SOUTH AFRICAThe Atlantic and Indian Oceans keep the climate mild, and our winter is Cape Town's summer What to do: Explore Table Mountain National Park and hang out with the penguins (yes!) on Boulders Beach (keep your distance, they bite!). For bigger wildlife thrills, head to Kruger National Park to see lions and elephants in the wild. Cape Town is where the Atlantic Ocean meets the Indian Ocean; the west side is best for soaking up the sun, the east side for swimming and surfing. Where to stay: Andros Boutique Hotel (from around $165)

Indulge your inner Julia Child on your next vacation—no plane ticket to Paris necessary. A new hands-on cooking class deal from Travelzoo offers half-priced courses from Le Cordon Bleu chefs at Bleu Ribbon Kitchen locations in 16 U.S. cities: Atlanta, Austin, Boston, Chicago, Dallas, Las Vegas, Miami, Minneapolis, Orlando, Pasadena, Portland, Sacramento, San Francisco, Scottsdale, and Seattle. Classes are $59 for individuals (down from $125) and $109 for couples (normally $250). Why not build a whole mini getaway around one? We especially like the sound of the Flavors of the World classes, with mouth-watering offerings like: • A one-day dim sum workshop. You'll learn to prepare dishes such as coconut buns, shumai, juicy steamed rolls, and shrimp toast (available in Austin, Chicago, Dallas, Miami, Pasadena, Portland, San Francisco, St. Louis). • Three different French Bistro Series classes, including Brunch in Paris, Roast Chicken Supper, and Steak Frites (locations for individual courses vary). • A class on Thai street foods.

Grab the deal by Feb. 1, 2016 at Travelzoo.com. Each student also goes home with a Bleu Ribbon apron and recipes from the class—but the real souvenir is the brand-new know-how.

Please note that package prices do not include international airfare, but do cover all ground transportation, a large amount of guided tours and activities, and most meals once you get there. I've traveled with Contiki twice so far—the first time on their London & Paris Plus Paris Extension tour in 2013, pictured above, the second time last May on their Amsterdam to Barcelona tour—and I'm constantly looking through their site trying to narrow down my next adventure, probably in Australia next year if I can swing it. My favorite part of the trips is meeting a whole bunch of friendly young people from all over the world who love to travel as much as I do. I've gone on both trips by myself and as a solo traveler, I was thrilled to learn that Contiki never charges extra solo supplements if you're traveling alone. There's an option to have your own room that costs a bit extra, but otherwise you're paired up with a single traveling roommate of the same sex. Translation: instant new friend. You're basically sightseeing by day and have the option to go out and explore the nightlife of a new city within the safety of a group, something that was really important to me and works out great because people are able to do as much dancing til dawn as they want to, no pressure. If you're worried about being hauled around on a bus all over the continent, think of it as a mobile-UN unit where you will inevitably get into fascinating conversations with your fellow travelers and end up talking about how things are done where you come from vs. how things are done where they come from. It always hits me how little we (Americans) know about what goes on in Canada, Australia, and the rest of the world during these chats, so I treasure these spontaneous educational moments. Plus, there's plenty of beautiful scenery to look at along the way and if you need it, time to rest up so you're ready to hit the ground running by the time you get to the next city. The rest stops are fun, too. I remember nodding off and waking up somewhere between Amsterdam and Paris, asking our Trip Manager, "Which country are we in? What language are they speaking in that building?" It's amazing how quickly a big group will bond on trips like these. I still keep in touch with lots of people I've met on each trip a year or even two years later on a regular basis thanks to the power of social media. A few of my new friends from Australia have even come to visit me here in New York and I know of several others who re-connected once they got home and have gone on more trips together.
