Since 1986. Winterfest is an annual event sponsored by the Chamber of Commerce. Visitors and residents alike will be out by the thousands for Annual Winterfest. Over 200 vendors from across the United States invite everyone to shop, browse, relax, and enjoy Lake Havasu City's unique culture. Winterfest offers more than booths – there’s entertainment, activities for youngsters, and more. Plan now to join the crowd for two spectacular days of arts, crafts, clothing, jewelry, home decor, tasty street- food, beer garden, and eclectic entertainment!
