Boston winters are long and cold—no doubt. But a surefire (and blessedly simple) way to shake off a case of cabin fever is to bundle up and head outside for a winter hike or walk. From the heart of the city to the hilly suburbs, Massachusetts boasts many paved or wooded trails that are as majestic in winter as they are in spring or summer, whether dusted or just swept bare by the elements.

If Mother Nature delivers more than a few inches of snow, consider trying out one of the places to snowshoe with kids around Boston instead. Kiddos feeling lazy? A stop at a Boston cafe with great hot cocoa or the promise of a homemade hot chocolate bomb treat to follow your outing is sure to sweeten the deal.

Atlanta is boiling in the summer, icy in the winter, and a wet mess during the rainy season, so free indoor playgrounds can offer relief for kids to run around without hefty fees and entrance costs. And besides the happy moment of watching your children run off that pent-up energy in a place other than your own house, it's also a perk to have saved some cash in the process.

If it seems like colleges are becoming more competitive, you're not imagining it. These days good grades, great SAT scores, and solid extracurriculars don't always cut it—many colleges also want to see some hands-on, real-world experience. That's where summer internships come in. While many summer internship programs are geared towards college students, the DC area offers plenty of programs for high school students with a variety of interests.

Here are seven great summer internship opportunities near DC for teens. These internships in the fields of STEM, biomedical research, history, and more will really help your child stand out from the pack. The opportunities are listed in order of application deadline, so keep a close eye on them—the deadlines fall before most teens have started thinking about their summer plans. As these programs tend to be competitive, encourage your teen to get an early start on applications.

Whatever summer internship or job your teen ends up with, they'll still need to make time for fun. Check out our Summer Activities Guide for DC Kids and our list of 12 fun things to do with tweens and teens near DC for ideas that will impress even the most jaded teen.
