We went camping and enjoyed natural sights/views/scenes/scenery: -the views -the scenery -'scenes' is usually referring to a play/drama/TV show/movie. -'natural sights' sounds a bit strange. -we enjoyed the nature is OK.

Better: 1. We went camping and enjoyed nature. 2. We went camping and saw some amazing natural sights. (a canyon, a valley, a rock formation) 3. We went camping and saw some beautiful views. 4. We went camping and enjoyed the beautiful scenery.
