I am extremely disappointed with this book, especially since it comes from National Geographic. I expected more from them. Once again, a book that is supposed to showcase ALL of our national parks does a half-a$& job of it.
First, this book is broken down geographically, so as to allow the reader to look at parks in small chunks (their words), but the only parks the reader really gets to sink their teeth into are the larger or most popular destinations. For example, Haleakala, which is located on the island of Maui in Hawaii. There is information (including basic locations) of their Visitor Centers, colorful photos, a map of the park, information about key locations within the park, including mentions of sites "Not To Be Missed," and a sidebar about Haleakala's prominence in Hawaiian Mythology. I actually visited Haleakala two years ago and found this information to be most interesting, but one secret that I am surprised was not shared and what Haleakala is best known for: How to watch one of their gorgeous sunrises!
In contrast, let's look at Cuyahoga Valley National Park, which barely "earned" one paragraph that is a little less than one half of one page. There are no colorful photographs or maps, here, and the information provided could be found online, so I'm not really sure that any of their "travel writers" actually visited the park. There is so much to see and do in this park! The book mentions nothing about the wonderful trails and waterfalls that are waiting to be discovered, including Brandywine Falls and Blue Hen Falls. There is a heronry to watch Great Blue Herons when they come back to nest, each spring. Part of the Buckeye Trail (state hiking trail) goes through the CVNP, and besides the Farmer's Market at Howe Meadow, which by the way is the ONLY Farmer's Market located within the boundaries of a national park, there is also Szalay's. Let's talk more about the Beaver Marsh, which was built on the grounds of an old junkyard, or all of the flora and fauna that live within the park. Finally, nothing was mentioned about the Towpath Trail, which runs parallel to the Ohio and Erie Canal, some of which can still be seen, today, including remnants of locks.
Much more time could have been spent on Cuyahoga Valley National Park which attracted 2.2 million visitors in 2019, as well as the other parks that are part of the "More Park Secrets" under each geographic region.
