The Sink or Swim Trail sidles across the Snow King ski slops not far above Jackson. At its western end it links to Josie's Ridge Trail and at its eastern end it joins Ferrins Trail. It's best ridden east to west, ie, from the Cache Creek end, because that way you get a slightly down-sloping ride. It's non-threatening but there are some stones and roots to navigate so you need better than intermediate skills to enjoy it. There are nice views over town, the Elk Refuge and the Tetons.
