Let's be honest; the best way to avoid sleeping on a rock while camping is not to sleep on the ground. Sleep midair in the Suspended Tent "Sky Nest" by Snow Peak.
The Sky Nest is spacious, comfortable, and easy to setup. Once you're suspended you'll have great views of your surroundings through the mesh on all sides. There's even a shoe pouch on the bottom of the tent to keep them safe and dry. The tent measures 220cm x 110cm x 130cm.
