The area is primary reserved for Caving rescue exercises and training for caving. If you see the exercise, you give way. They have priority in using the area.
Respect the locals!! You can engage with normal conversation and respect if they ask you about anything.
Take ALL the trash with you and not in the Bins around..(those are not necessarily trash bins. If you see any gear and material, do not take it or steal it. They are there for the caving exercises.
