A scenic route across the bench above the Santa Ana River. Front-Line Road (Forest Service road 1N04) runs from the bottom of Clark’s Grade (1N54) to Highway 38 just above it’s crossing over the Santa Ana, making it a good connector road between other routes in the area. The road features several stream crossings, wide meadows and sweeping views of the slopes of Mount San Gorgonio on the other side of the gorge.

Trail Rating: EASY

Easy trails are suitable for stock 4X4’s as well as 2WD trucks and SUV’s with sturdy tires and good ground clearance. These may include seldom-maintained forest roads with occasional mild obstacles including ruts from runoff, mild rocky sections and moderate grades. Some sort of traction control device such as a limited slip in at least one differential may be helpful in some places but careful tire placement should suffice for 2WD vehicles with an open diff. Airing down is generally not necessary but may be beneficial for ride comfort. As road conditions may change, travel in groups and carry recovery and emergency equipment.
