Loads of spots to camp around here, we explored (I think) 703C and when there were no spots on that road went to 703J, no problems driving down anything in the Toyota Corolla we'd rented. You can pickup a map of the roads detailing exactly where you are allowed to camp at the start of the area. Campsite we found was right at the end of 703J and was nice enough although there were more mosquitos than I have seen in my life! Bug spray stopped them biting but we couldn't stop them swarming around us!
