In celebration of National Parks week, Travel Lemming released a data-backed ranking of all 63 US national parks. Indiana Dunes National Park ranked #42 overall, due to data indicating it is the second-worst reviewed and fourth most-crowded park in the nation.

Travel Lemming’s national parks ranking is based on an analysis of data scoring each park across six factors: affordability, accessibility, biodiversity, crowds, reviews, and weather.

The report revealed the following insights regarding Indiana’s only national park:

  • Indiana Dunes National Park ranked #42 overall. Despite high marks for biodiversity and accessibility, its overall ranking was impacted by below average reviews and heavy crowds.
  • Indiana Dunes received the second-worst average user reviews in the USA, ahead of only Alaska’s Kobuk Valley National Park. While most national parks receive stellar reviews, on average visitors rated Indiana Dunes only 4.2 out of 5 stars.
  • Indiana Dunes is also the fourth most crowded in the country, with over 184 visits per acre of park land. This placed it ahead of only three parks in the crowds factor.
  • The park performed better in the biodiversity category, due to its 1,964 species. It also did well in terms of accessibility, ranking 6th in the nation due to its close proximity to multiple airports.

The top 10 US national parks in the USA according the report are:

The most famous national parks fared surprisingly poorly in the data, largely due to the crowds and affordability factors. Grand Canyon National Park was ranked #15, Yellowstone National Park at position #23, and Yosemite National Park at slot #34. 

Travel Lemming Senior Travel Writer McKenna Mobley commented: “I have traveled the world, and can confidently say that the USA national parks are unparalleled, making them one of my all-time favorite travel destinations. Every US national park offers its own special flair, so in some sense ranking them is like ranking music genres — they’re all good!”

“However, I hope this report highlights the fact that some of America’s less famous parks offer far more than what meets the eye. Sometimes the best experiences can be found at hidden park gems that are off the lemming path.”
