What has already been posted is good advise. Beyond that, I'd suggest either going out of the Calaveras Picnic area in the North end or the Campgrounds in the South end. If you go to the Campgrounds remember that you can't park for the day in there on a day pass. You can however park there long enough to unload your gear. Go the the campsites at the North end of the campground and unload, I usually carry my Kick down to the water, then I park on the road. If you turn right when leaving the campground and park just after the end of the guard rail before the 1 lane section, there is a trail that will take you back down to the Northern most campsite. On the East bank of the lake, directly across from this campsite, between the rocky point and the wooded point is where I've done the best for my last 5 trips in 17 days.
Tight lines,
Wade
