Which lodge in the National Park System do you head to for the best value, and what makes it the best value?

For $25, you can drive into Yellowstone or Yosemite national parks, your car loaded with family, and spend the rest of the week exploring. At Mesa Verde National Park, after paying the park's $15 entrance fee, another $25 fee will get you -- only you, not your entire family -- on a two-hour hike to either Mug House or Square Tower House.

To help mark National Get Outdoors Day, all units of the National Park System will be free to enter this Saturday.
