This guide book written by the legendary Potrero route setter Magic Ed is the only book that is updated annually. It is by far the most accurate and complete guide book for the area with the newest routes listed and detailed multi-pitch topos drawn. Sadly it lacks the vivid crag images with labeled route pictures that The Whole Enchilada features.

Climb El Potrero Chico is currently in its 17th edition with a green cover. It can be bought at various places around Potrero Chico, most notably at the office of La Posada or directly from Magic Ed and his van. Buying this book supports the maintenance and expansion of Potrero Chico routes.
