The Whooptie Trail is a great alternative if you are trying to dodge the crowds in Post Canyon. All XC riding, it is generally done in a counter clockwise direction to minimize the uphill grind at the end of the ride. Regardless of direction there is climbing involved - leave your full face at home. Dependent on the direction and start location this is generally a 1.5 to 2 hour ride. Check in with a local bike shop for specific info and directions.
