The Pothole dome is a short easy trail. Total distance is about 2.5 mile, elevation gain is about 200 feet. The trailhead parking is right along the Tioga Road (T18 if you looks for Road mark). The Parking lot can hold about a dozen cars.
The trail is better to be hiked clockwise. It starts at the west end of the parking lot, a big curve to the foot of the Dome. There is no clear path to the top of the dome, but most people will start to climb when they meet the first fork , left side leads you to the top of Dome, it is less steep. The right fork leads along the edge of the meadow to the Tuolumne River. Once you climb to the top, and plan to descend the dome, you just head straight North, you will reach the trail along the river. Follow the trail and the water sound, you reach the Secret Tuolumne River Cascade. It is a picturesque cascade and a good swimming pit.
Once you are done with the cascade, you can follow the trail between the river and dome, and return to the parking lot in a mile. Be sure to check the Cathedral Peak and other surrounding mountains along the return path.
