The Joshua Tree National Park Art Festival has been celebrating the inspiration of nature for 20 years. Over thirty local and regional artists will be on hand this weekend at the festival to show and sell their work, sharing their personal interpretation of Joshua Tree National Park and the desert southwest. Original works of painting, sculpture, photography, ceramics, art glass, jewelry, woodcrafting and gourd art are featured each year. The Art Festival runs from 9:00 to 5:00 p.m. today, Saturday, and Sunday on the Park Headquarters patio near the historic Oasis of Mara nature trail on Utah Trail in Twentynine Palms. Admission is free.
