Driving from Napa, the closet launch ramps are the Steele Canyon Recreation Area (a $23.00 launch fee) or Capell Cove launch ramp. Once on the water, use the above map to find skier's cove on the southern section of the lake. Slow to 5mph as you are entering the cove. Best not to ski right outside the course either- it's a bummer for the course skiers that have to deal with your rollers.
