Is there one particular national park campground you like to return to again and again and again?

There are so many components that go into a successful national park escape. Travel to the park of your choice, comfortable and reasonably priced lodging, well-marked trails to explore, good interpretive programs, and nutritious, tasty meals are just some of the most obvious aspects. What's most important in your estimation to a successful park trip?

Across the National Park System you'll encounter some pretty incredible interpretive programs. In Virgin Islands National Park there are underwater trails. At Mammoth Cave and Sequoia national parks you can go on a "wild cave" tour. Let fellow travelers know which national park interpretive programs you've found to be extraordinary.

How do you navigate your national park visits? Are you someone who needs to actually experience the tactility of a printed and bound guidebook, one with pages that can be dog-eared, notated, cluttered with Post-its, and tossed into the backseat when you're done with it? Or are you right at home with a digital guidebook, whether the material is displayed on an iPhone, iPod, iPod touch, or some similar digital media device?

With winter not too far off here in the Rockies, it's only natural to begin to consider which national park to visit before the spring thaw arrives. Our question to you: Do you focus on snow, or sand, when you think of a winter national park escape?

Fall is here in the Rockies, and winter won't be far behind. For many that means outdoor adventures are being shunted to the back burner. But it also means there's lots of time to plan next year's epic adventures in the National Park System. So what treks are you mulling?

It's fall. There's a crispness in the air, trees are painting the landscape with their colorful leaves, elk are in the rut. And in some national parks, hunters are being dispatched to tamp down those elk populations. Is that the right way to approach wildlife management in the National Park System?

We're at the halfway mark of The National Parks: America’s Best Idea. So what do you think? Has Ken Burns pulled off another masterpiece, or do you find it lacking in some regards?

For 364 days a year, the brain trust here at the Traveler tries to come up with thoughtful, occasionally thought-provoking, entertaining, and informative posts on the National Park System. Today we turn the editorial keys over to you.

Quick, pick an ocean setting for next summer's national park vacation. Are you heading to the Northeast, the Northwest, or looking South or somewhere else for your destination?

It never fails. Before heading out to a national park, my wife and I always remind each other to grab the birding guide. And we always forget it. Which raises a question: What item do you always make sure is in your duffel for your national park trips?

Hard to believe, but already the Wasatch maples are starting to take on the hues of fall here in Utah. Which means the colorful kaleidoscope of fall cannot be far off. With that in mind, which national park is your favorite for fall leaf-peeping?

If you've stood before Old Faithful as it erupts against a golden sunset, or perhaps a frosty sunrise, you're likely going to carry that image with you for the rest of your life. Or maybe the profile of Half Dome, as seen from Glacier Point in Yosemite National Park, leaps first to mind when you think of national parks.

So, how was your latest visit to a national park? Were rangers present to answer your questions? How was the parking? Restrooms clean? We'd like to hear from you.

If cost were no object, whose national park painting would you hang on your wall? Would it be a Thomas Moran, an Albert Bierstadt, or a Maynard Dixon?

Have you ever had the itch to fly over the Grand Canyon in a helicopter? Do you want a bird's eye view of Crater Lake? Or do you believe the airspace over national parks should be reserved strictly for, well, the birds?

What's your favorite trail in the National Park System? That can be a tough question. Some believe hiking the "Narrows" in Zion National Park is as good as it gets. Others might say a multi-day outing on the John Muir Trail through Yosemite National Park down to Devil's Postpile and on to Sequoia National Park and Mount Whitney is the best there is.

Tell us what your favorite national park is, and why.

Earlier this summer Interior Secretary Ken Salazar designated three weekends as "entrance free" weekends in the National Park System. Anecdotally, the first of those three weekends attracted larger-than-normal turnouts to many parks. Which makes us wonder, do you mind paying entrance fees, or should they be eliminated?

While we at the Traveler have in the past raised the issue of what units of the National Park System should be jettisoned, today's survey is just the opposite. Tell us what you would like to see added to the system.
