Summer memberships come in handy as the costs to entertain kids over the next couple months really start to add up. If your kids develop a deep devotion to the Bronx Zoo, like ours did, a single visit can cost almost as much as your electric bill. And, for us, that's where purchasing a zoo membership came into focus.

A family membership can also help make other favorite summertime destinations more affordable: botanic gardens, museums, and—naturally—pools and beach clubs. While the city's outdoor pools don't require summer memberships, they do get crowded, so we've rounded up some other options for family-friendly memberships, including pool memberships, zoo memberships, and more spots for summer fun indoors and out. No matter your family's interest, take note: While the initial investment of a family summer membership can be pricey, do the math and consider how frequently you'll visit. You're likely to find that these family membership deals are worth the splurge. Looking for a family membership for the cool weather months?

Arlington National Cemetery is one of the oldest and most famous cemeteries in the US. Established in 1864, this hallowed ground serves as the final resting place of over 400,000 veterans and their spouses and children. Service members from every major American war are interred there, as well as many famous Americans including Presidents John F. Kennedy and William Howard Taft, Supreme Court Justice Ruth Bader Ginsburg, and astronaut John Glenn.

With its rows and rows of perfectly aligned, identical white headstones, Arlington National Cemetery is a truly breathtaking sight. But while it is indeed a solemn place, it is also a wonderful place to visit with kids and teach them about American history. Arlington National Cemetery's beauty and historical significance have landed it on our lists of 100 things to do in DC with kids before they grow up and the top tourist attractions in DC.

The Freedom Trail is an excellent way to introduce kids to the rich history of our city, as well as a fun family outing. When we made our own family outing to this series of Boston landmarks, my seven-year-old twins were as excited as I was about the things we were about to see. We'd recently read a book about Paul Revere, and had gone out to Concord to see one of the Patriots' Day reenactments, so they were definitely primed for some juicy history.

Keep in mind that while the Freedom Trail encompasses 2.5 miles of 16-plus historical sites, many of them can be viewed from the sidewalk or entered briefly for a quick look around. You'll only want to plan extra time for the types of sites that spark kids' curiosity—otherwise, it's a long day. We think the following are must-see stops with kids:

There are multiple activities and food options that make Bushkill Falls a popular destination for Northeast families.
