Spectacular scenic opportunities abound in one of the largest and flattest alkaline playas in the United States. The Playa is a now-dry remnant of ancient Lake Lahontan; it is 44 miles long (oriented north-south), and averages 7 miles in width. Opportunities for solitude are considerable. A variety of interesting geologic features dominate the landscape. The near-pristine Applegate-Lassen section of the California National Historic Trail traverses the Playa.
