This book covers 32 of the best hot springs in the state of Colorado. Since Carl Wambach's first edition was published in 1999, most of the developed hot springs have changed their names, upgraded their facilities and added numerous structures and amenities. Renovations vary from ongoing maintenance to multi-million-dollar overhauls, and the current status of each hot spring is detailed in the second edition of the book. A common theme is the addition of spa and massage facilities, lodging and a move toward green initiatives.

Of the original 29 hot springs, one—Splashland—has been removed, while four more have been added: Piedra River, Dunton, Antero, and Pinkerton. In addition to the original data points in the planning section, the reviser added information on wheelchair access, and accommodations other than camping, like RV hookups, motels, lodges, bunkhouses and cabins. Under “maps” she added the DeLorme Colorado Gazetteer page and grid number for each site, and added a section called “contact info” listing the physical address, phone number, email address and website URL to each hot spring. All other information in the planning section—general description, location, development, best time to visit, restrictions, access, water temperature, services, GPS coordinates, and finding the springs—has been verified and updated for accuracy.
