When you're planning a caving expedition, it's important to weigh the risks and rewards of the trip. If you're part of a scientific or geological team, you've received the necessary training to safely explore a cave and you have a specific goal in mind once you enter the cave. You've also packed the proper caving equipment and know how to use it correctly. If you're a beginning caver, it's imperative that you never enter a cave on your own and that you complete training courses before you set out on your trip.
Caving is a serious endeavor, and it should never be taken lightly. The rewards include seeing formations and chambers that very few others have seen, but the risks include hunger, serious injury, or worse. You should be prepared for grueling crawls through narrow passages and walking through damp chambers. Having the right equipment and clothing can protect your from hypothermia, starvation, and injury, and letting someone outside the cave know when you're going in and when you plan to come out is also important. You can also encounter cave-dwelling organisms and animals, and it's important to treat them with respect and observe them from a distance.
Weighing the risks and rewards of caving might make you hesitant to set out on an expedition, but the desire to see what lies under the earth's surface may prove more powerful. It's true that caving can be a perilous undertaking, but with the proper equipment and training, you can safely traverse any cave in the world.
