Next weekend, August 14-15, is the third, and final, fee free weekend in America's national parks for 2010. For those two days, more than 100 of the parks will open their gates to the public at no cost, giving visitors a chance to experience "America's best idea" for themselves.

The complete list of parks that will be waiving their entry fees can be found by clicking here. That list includes such spectacular icons as Yosemite, Yellowstone, and Acadia, as well as lesser known, but no less amazing, parks like Big Bend, the Dry Tortugas, and Crater Lake. All told, more than 40 states are represented on the list, which means there is a national park or monument that will be free to visit next weekend near just about everyone in the U.S.

The fee free weekends have been very popular that past few years, and crowds in the parks will no doubt be high. But if you can't make it out to your favorite national park on the 14th or 15th, never fear, as there are still two more fee free days to come in 2010. On Saturday, Sept. 25th, the parks will be free in celebration of Public Lands Day and then once again on Thursday, Nov. 11th, in honor of Veteran's Day.

With summer quickly coming to a close, take advantage of this last fee free weekend of the year for some outdoor fun and adventure.
