The Big Kahuna

This is a route from Max Walter's 'North State Single Track' book.  It's not very technical at all, especially since the fire crews made a smooth road out of the Boulder Creek Trail a year or two ago.  You'll want your lightweight hardtail for this one.  It has one gutwrenching climb on the Mill Creek Trail, but aside from that it's easy rolling.  These instructions are lousy; if you want better ones please buy the book.  Park at Oak Bottom and pick up the Oak Bottom Trail heading west.  Intersect a paved road and after a bit turn left toward Carr Powerhouse.  Cross the bridge and turn right onto the Clear Creek Vista Trail.  Cross the creek and turn right.  Just past the El Dorado Mine turn left onto the singletrack.  Turn right at the mini cemetery, then left across the bridge at the Camden House and left again onto highway 299.  Left onto Crystal Creek Rd. and keep going to the Whiskeytown Falls trailhead and turn onto the trail.  Turn left onto the Mill Creek trail.  Up, past a gate, down, slight up and take a hard right at another gate onto the Boulder Creek Trail.  Descend to South Shore Drive and turn left.  Turn right onto the paved road, pass Carr Powerhouse, and backtrack to Oak Bottom the same way you came in earlier.
