Planning a birthday party for a tween or a teen? As your child heads into the teenage years, it can be difficult to find the right way to celebrate a birthday. Chances are, she's well beyond the princess or super hero thing, and going to the movies with friends may not be special enough. Since a hallmark of young adults is that they try to be more like adults, a spa party booked with professionals and a few close friends at a salon can be just the right answer.

While some spas specialize in massage and facials, others only do manicures and pedicures—it pays to do some research ahead of time. Here are few of our favorite spots to book your teen’s next birthday or get-together in Westchester.

A brand-new, multi-borough kids festival with magicians, hands-on preschooler art and a Paris-trained circus troupe kicks off Friday, March 4 in New York City. It's not every day that a monthlong cultural fest dedicated to kids arrives, especially in the dead of winter, so we were excited to learn more. 

Dry skin or not, for this family, it’s time to start getting back in the pool.  And although it’s warm, it’s not quite warm enough to hit the Long Island Sound!  Instead, check out some of these indoor swimming options in Fairfield County:

The Children's Museum of Manhattan has long been my go-to spot for maximum tot fun, but when it comes to learning about art, architecture and other cultures, we usually headed elsewhere. The newly-opened America to Zanzibar: Muslim Cultures Near and Far exhibit will change that.

Opened last week, the 3,000-square-foot exhibit takes up the entirety of the museum's first-floor exhibition space and provides a colorful, immersive window into Muslim cultures across the world. The exhibit has been extended through January 2018 and is the fourth in the museum's Global Exhibition Series, which previously highlighted the cultures of Ancient Greece, China and Japan. Read on for the scoop on this vibrant new exhibit.

After witnessing several big-name kid stores shutter Midtown locations, we were happy to learn that Nintendo NYC took a different approach. The gaming paradise overhauled its flagship Rockefeller Center location over the last month, reopening on Friday, February 19 with lots of fun new interactive features, ensuring its place on our list of favorite indoor places to play for years to come. 

The two-story, 10,000-square-foot Rockefeller shop also displayed a new name, going from Nintendo World to Nintendo New York, or Nintendo NYC for short. We visited on opening weekend (despite the epic lines!), and it's definitely a spot to add to the NYC must-visit list for gamers and nostalgia fans. Read on for the details like a 15-foot gaming screen, a display of Game Boys from years past and even a sneak peek at the latest Zelda.

The Chestnut Hill East SEPTA train serves Chestnut Hill, Mt Airy, and Germantown. Rich in history and cultural experiences, this could easily become a favorite SEPTA line. In the summer, plenty of parks and playgrounds are worth checking out, as well as many fun family excursions. As always our events calendar is chock-full of fun times, but here are our top family activities along the Chestnut Hill East line. 

Somerville is a fun and funky home to artists, musicians, urban farmers, festivals, and makers and creators of all stripes. Whether your children want to learn to garden, build a lightsaber or play in a brass band, there’s an organization in Somerville just for them. These groups – Groundwork Somerville, Parts and Crafts, and School of HONK – provide unique enrichment activities to kids and families in the community. The programs offered are free, inexpensive, or on a sliding scale to give everyone the chance to participate.
