K2 trekkers on Instagram: "Climbing mountains above 8000m without proper knowledge, a guide, or high-altitude porter support is extremely dangerous and often fatal. The mountain's harsh weather, technical routes, and thin air above 8,000 meters demand experience, physical endurance, and support. Without trained guidance, climbers risk getting lost, exhausted, or succumbing to altitude sickness, with little chance of rescue. Such an attempt is highly irresponsible and can easily lead to death. he
