Y Mountain is mountain located directly east of Brigham Young University (BYU) in Provo, Utah, United States. The Slide Canyon/Y Mountain Trail leads to a large block Y located 1.2 miles (1.9 km) from a parking area at the mountain's base. This hillside letter was built over a hundred years ago as the insignia for BYU. For years the trail to the Y has been one of the most hiked trails in Utah Valley and provides a scenic view of Provo and Orem, the rest of the many cities in Utah Valley and Utah Lake.
