At Mile 30 you will come to a Fork in the road! If you go right you will go to Pashagshak State Park , Narrow Cape, Fossil Beach, Rocket Launch Site. To go to Chiniak you must turn left! Notice the bullet holes in the sign!
The Chiniak highway is not paved. So drive carefully. It is best to drive early in the day, or after a rain, so the dust doesn't blind you. Along the way you will be treated to spectacular views, and may see all manner of wildlife.
The road to Chiniak is mostly crushed rock so it can eat your tires up!! But the drive is beautiful!!
Just in case you really want to leave the Chiniak Highway, there is a short road. It is a dead end, but so is the highway. Hey, they erected a street sign, so it must be important.
