You can start out on the Gasline Road at 267, the pullout just below it on the Kings Beach side or Beaver Street on the east side of KB. From the pullout, the singletrack merges with the Gas Line Road
firetrail after a short time, so that's the ride I like.
You can also start at Cambridge Dr (where the trail ends), and ride up a short trail + road via Canterbury and Commonwealth, which leads to a short singletrack section onto Gas Line Road
fire trail. No highway riding that way!
Gas Line is a dirt road marked with occasional yellow "gas line" markers up and to the East. When you reach Griff Creek you'll have to dismount and carry your bike over a giant log and over a small creek.
From there, the road will climb steeply for a short bit and switchback to a mellow more sustainable grade with occasional lake views out to your right. Continue following the Gas Line Road
for about another mile or so until another dirt road joins in from the left. Just past this intersection is a pretty obvious open area that functions as a motorcycle turn around. At the South end of this open area (on your right) is the start of the Rise and Shine DH. It's marked with a brown sign labeled "18".
The trail starts with a mellow section of flattish terrain, then shortly after, it dives into a series of turns with fun flow, fantastic lake views, and a decent amount of pitch. As the trail mellows and you return to the coverage of the denser forest a trail will merge in from the right.
This is a singletrack that can be climbed and takes you back to the Gas Line Road
just above the creek crossing. (This trail makes the ride a pretty fun lollipop route if you don't want to climb 267 and the Gas Line Road
or shuttle to the Gas Line road.) Continue on past this intersection and through a bit more flowy fun and bear right at the next intersections to end at the cul-de-sac of Cambridge Dr. (Bearing left at the major intersections takes you down a bit further toward the 'old mill' and the fire road heading North from the grid at Deer St.)
These trails are open to motorized use, but most of the traffic is bikes.
