Fun, moderate singletrack, and a great intro to South Tahoe riding.
There are easy shuttle options, and often plenty of folks parked to set up a quick one.
From South Lake Tahoe, take Pioneer Trail
towards Meyers and turn left onto Oneidas Drive. Take Oneidas as it narrows, and if the gates are closed, park and ride up the road. Otherwise, you can park at a well-established parking lot, or work the shuttle up to the bottom of the Connector Trail
/top of the Corral trail.
Assuming you parked at the bottom, ride up the narrow, nicely paved road for 2-3 miles. At the top of the Corral, either ride up the Connector Trail
, a nice singletrack climb, or continue up the paved road. Then descend the connector, pick up the Corral, air it out on some of the kickers, enjoy the banked turns, and cruise back to Powerline dirt road. Take a left, and you'll get back to the parking lot in short order.
