Happy Wanderer
Format: Flexibound
City Trails is not a guided walking tour (like the Freedom Trail here in Boston) of the Metro DC area. No addresses or street names are noted in the blurbs. To actually visit any of these places, you’ll have to consult a real map. For instance, the chapter “Statue City” highlights notable statuary around town. But the Capitol Building statues (in SE DC) are far from the Cathedral ones (in NW DC.) The themed groupings (G-G-G-Ghosts, Animals Around Town, Water World and more) are less maps to any place and more of an interesting overview of our Nation’s amazingly diverse and action-packed city. It’s best read as a primer on experiencing the flavor of the city (I lived and worked there.) It reads more along the lines of the “Weird But True” series made famous by National Geographic for Kids.
I don’t see this being of value to tourists in town for a limited time whose sightseeing is going to include major attractions like government buildings (White House, Capitol), museums (Smithsonian), some monuments (Jefferson, Lincoln, Washington) and other popular sites (Ford’s Theater.) This guide is actually best suited for the Metro-area (WDC, MD and VA) resident – child or adult - who wants a deeper dive into their hometown’s off-the-beaten-path sights and stories. A well designed and written book of historical trivia.

Nice way to learn about a trip to D.C.
Format: Flexibound
I got this for my kids to read before we went to Washington D.C. The pages are colorful, illustrated, and have short bursts of interesting details about the various attractions available to tourists who are visiting. My kids were eager to find the places on our itinerary and read about them ahead of time. They learned what to expect and were sure not to miss the important aspects of our tours. This book is recommended for 9 to 12 year olds and I think that is the perfect range. There is just enough information to peak their interest and not so much that they get bored by reading a bunch of text. The Table of Contents wasn't that informative in finding specific places, but the index was. My kids preferred to leaf through the whole book and find what was interesting to them.

Not good for travel, picture book only
Format: Flexibound
This is a beautiful book with fantastic illustrations and an engaging color palette. It includes a good variety of historical background information and sightseeing locations. However, it is a better picture book for browsing only. It is not a good travel book for kids to plan their own adventures. Who has ever heard of a travel book without maps?! No maps, no directions, no coordinating subway/bus maps. The printing is exceptionally small, almost too small to read. The book should have been made larger to accommodate the text. The text is excellent, but it printed as if the publisher never expected the kid/parent to read it. On one hand, our family really enjoyed how engaging the book appeared, but we were disappointed in its quality as a travel book. It shouldn’t be marketed as a travel book, but a geography book series.
