The trail provides an enjoyable casual drive, bathed in the cool green of the tall pine trees lining the cool green. Santa Ana River Road passes over its namesake, the Santa Ana River, or its tributaries in several places. It provides inviting areas to pull over and walk down to the water's side to enjoy the peaceful forest river and its comforting sounds. Santa Ana River Road is in the 823,000-acre San Bernardino National Forest just south of Big Bear Lake. The Santa Ana River begins its journey in the San Gorgonio Wilderness, high above the trees. It is one of Southern California's largest and longest rivers, tumbling 80 miles to the Pacific Ocean. The Prado and Seven Oaks Dams interrupt the river, providing flood control and water for consumption, irrigation, industry, and recreation. This area around the Santa Ana River is a unique and fragile ecosystem,
