Start on Gold Camp Road just before the seven bridges trailhead, you'll see the entrance off to the right as it heads uphill. After a short, technical climb, the trail makes a sharp right turn to the east and continues uphill.
Just keep on climbing until you reach the saddle. Turn right at the saddle, follow the ridgeline and you'll be rewarded with a view of the entire canyon.
From here it's a moderately techy run down to High Drive and the start of Captain Jack's trail.
