When it’s time for a fun family vacation, one of America’s most popular choices is staying at local camping sites. In 2010, for example, around 400 million people went on camping trips.

The next year, in 2011, families spent 534.9 million days at family camping vacation spots. Then in 2013, the 2014 American Camper Report stated that 40.1 million people six and older went camping as well.

Why do so many families go camping together? First of all, many parents went on family camping vacations when they were growing up, and developed a great love for this outdoor activity.

Quite a few adults–47% of those surveyed–said that they simply loved to camp and wanted to share this experience with their families. In fact, 13% of the adults surveyed said camping provides them with the ideal opportunity to spend quality time with their families.

Most families seem to prefer staying at pubic campgrounds, according to a recent survey of campers. Approximately 70% said that this worked out the best for them. This makes sense given all the amenities available at public camping grounds.

One of the main reasons people love to camp, of course, is due to all of the outdoor activities. Of the campers surveyed, 87% said this was their main motivation. From hiking or backpacking in wooded campgrounds, to swimming or boating in lakes, there are so many family-oriented activities for campers to enjoy.

When families stay at local camping sites, they can choose to sleep in tents, cabins, or even yurts. Due to the various amenities at public camping grounds, there are hook-ups for RVs as well.

How long do people stay at these local camping sites? Some families may go camping for a long weekend, while others stay a bit longer. According to a recent survey, families tend to spend an average of 14.9 days, which is basically two weeks.

When families go camping together, they have an opportunity to relax, enjoy each others company, and yes, engage in so many outdoor activities. In fact, since they’re having such a great time, they’ll usually begin planning their next family vacation.

Most campers surveyed said they planned to go camping around five more times, while approximately two-thirds of campers had three or more camping trips planned.
