Getting there is easy. From Scissors Crossing at highway 78 and S2, drive south 5.3 miles on highway S2. Keep watch for the "Little Blair" sign on the side of the road. Take this turn off to follow the trail in. Overall distance to parking area for pictographs is 5.5 miles. The road in is packed sand, single lane wide. The route is suitable for any SUV or truck as well as most cars. If you are in a car and see soft sand ahead, keep your speed and don't slow to help prevent getting stuck.
Primitive camping is also allowed in Blair Valley and there are many good areas for this along the driving trail.
There are giant Ocotillo plants along the way.
Leaving the parking area, begin to backtrack the main road; after a short distance you will find the trail for the Indian Morteros on the left. You will come to the three-way intersection after about 1.4 miles (measured from the pictograph parking area), stay left and look for the Indian Morteros sign. You can take this hike or continue on driving this alternate route back out to highway S2. Driving beyond Morteros sign, stay to the right, near the bluffs, where you will come across more good areas for primitive camping. Continue the driving trail a short distance and it leads out to highway S2. Turn right to return back toward Scissors Crossing.
While I have not camped out here, it seems like a great place for a weekend trip. Have you been camping here? What's your opinion for camping in Blair Valley?
