For those interested in exploring San Diego County’s desert, there has been one widely accepted guide book for the past 40 years.

The Anza-Borrego Desert Region guide, published in 1978 and now in its sixth edition, has been updated for the first time in more than a decade.

Published by Wilderness Press and written by Lowell and Diana Lindsay, the latest edition provides hikers and motorists with new detailed charts, maps and descriptions of hundreds of hikes and routes through the 650,000 acres of Anza-Borrego Desert State Park and adjacent areas.

“The biggest change is the hiking descriptions and charts we have in there,” said Diana Lindsay, 73. “It’s a mile-by-mile description as you’re driving down the roads, either the paved roads or the dirt roads, and it tells you at every stop what to see, what to look at, where all the hikes are.”
