Cavers are individuals who explore caves for recreation, research, or adventure. They often use specialized equipment, such as helmets, headlamps, and climbing gear, to navigate through dark and sometimes challenging environments. Caving can involve walking, climbing, or even swimming through underground passages and chambers. Caving is also known as spelunking in some regions, particularly in the United States. Cavers may study the unique geology, ecosystems, and formations found in caves, such as stalactites and stalagmites. Safety is a priority, as caves can present hazards like tight spaces, water, and unstable rock formations.
