The U.S. Forest Service offers fee-free days on the forest throughout the year, meaning that no Adventure Pass is required for those recreating on the San Bernardino National Forest (though campground fees still apply). Fee-free days for 2010 include National Trails Day on June 5 and 6, back-to-school season on August 14 and 15, National Public Lands Day on September 25 and, as always, Veterans Day on November 11. For specifics on the San Bernardino National Forest, which surrounds the Big Bear Valley, call the Big Bear Discovery Center at 909/866-3437.
