Fun Fact: It is common for climbers to forget to pack ear plugs, which can be essential items. If you are planning to climb Mount Kilimanjaro and you are sensitive to noise or a light sleeper, it is important to remember to bring earplugs. The high altitude can affect sleeping patterns and cause your fellow climbers to snore heavily, which may disturb your sleep. Therefore, earplugs can come in handy to ensure a good night's rest.
