Proper packing is extremely necessary for Poon Hill Trek. Actually, the weather could change quickly in the hills. Hence, pack such clothes that would keep you dry and warm. Start with moisture-wicking base layers. These do not allow sweat to touch your skin. Then layer up a fleece jacket or an insulation sweater. Likewise, a water-proof jacket is also required so that it would protect you from rain and wind. Moreover, you should also carry good trekking boots. They have to be comfortable and worn in advance of the trek. Thermal or wool socks ensure that your feet stay warm. Carry a hat to shield against the sun and carry a wool cap for chilly mornings and evenings. Gloves come in handy as it gets cold, especially early morning. Moreover, for your backpack, choose one with a capacity of between 30 and 40 liters. It should be light but have enough space to carry your basics. Take a 0°C or colder-rated sleeping bag since the nights will be cold. Carry a water bottle and water purification tablets so you can safely drink. Don't forget sunscreen, lip balm, and shades since the sun is strong at higher altitudes.
