The 22-mile Mountains to Sea Trail travels from the edge of the Cleveland National Forest to the Pacific Ocean. Considered the backbone of The Irvine Ranch open spaces, the trail begins in Weir Canyon and doesn’t stop until it reaches Upper Newport Bay. Located within minutes of bustling urban communities, the trail makes exploring the outdoors easy, fun and accessible. Irvine Company Chairman Donald Bren announced completion of the trail in 2005; the following year it was designated a “National Recreation Trail” by the National Recreation Trails Program.
