READERS' PICK: I can see for miles and miles and miles. Eventually this non-motorized continuous long-distance walkway will extend from the Coronado National Memorial on the U.S./Mexico border to the BLM Strip District on the Utah border. At the moment, 600 of the nearly 800 miles are signed and open for business. Both amateur hikers and ardent adventurers will find the more than 40 sections of the trail interesting as well as sometimes challenging. From the hills of Canelo to Grand Canyon National Park, this is "Leave No Trace" territory for those seeking solitude and a wilderness experience. "This trail is a treasure beyond belief," says Jan Hancock of the Arizona Trail Association. Find out why with a virtual visit via www.aztrail.org.
