great views down into Mexico. Trail begins at Engineer Springs, south of Dulzura on Hwy 94. Head
southwest on Marron Valley Road. After about 2.5 miles, you will see a sign for 'Doghouse Junction', turn
right here. After another 2 miles, you enter the Otay Mountain Wilderness. Stay on the main trail. You will
see numerous side roads, but stay on the main trail at all times. Most of these side roads are US Border
