Ride this as you would to get to the Gold Bar Rim / Gemini Bridges. Take 191 North and turn left before you get to 313. There should be a railroad crossing and a small parking lot. Ride up Gemini Bridge Trail until you get to a sign showing Gold bar rim to the left. Take the steep hill upward and ride until you come to a sign showing Bull Canyon left and Gemini Bridges right. Take a left. You are now on Bull Canyon trail. About another 1.5 miles you will come to an Y intersection. The left looks like its a dead end but further investigation will show it goes up the hill on your left. The right to take you into Bull Canyon. Take the left here. It is not marked (we missed it the first time). From here you climb up the hill and will see a distinct trail going towards Two Tortoise Rock. This is where I call the start of Two Tortoise trail.
