Utah, Utah.
Utah State Parks: Boat, fish, and swim on the tranquil waters at Gunlock Reservoir or enjoy an afternoon picnic on the beach. Warm waters during summer and a mild winter climate make the park a year-round destination. The county road to the park is the Old Spanish Trail used by horsemen and raiders from Sante Fe, New Mexico to Los Angeles from the 1820 s until the gold fields became the destination after 1849 and a shorter route was taken.
Nearby St. George offers big city amenities such as championship golf and outlets in the warm climate of southwestern Utah.
