Must-have gear for a trip to Western Sichuan in May

This checklist is clear and covers the core equipment for plateau/hiking trips, suitable for scenarios that require dealing with complex environments (such as high altitude, low temperatures, and hiking). Here are some optimized suggestions and supplementary notes for the checklist to help you prepare your luggage more efficiently: I. Clothing, Shoes, and Hats: Layering for Flexibility ✅ Optimization Suggestions: 1. Layering formula (for temperature differences & hiking perspiration): - Inner layer: Quick-drying clothes (mainly for perspiration, avoid cotton clothes that lose temperature after absorbing sweat) - Middle layer: Fleece/down liner (warm, detachable to cope with indoor and outdoor temperature differences) - Outer layer: Windproof and waterproof jacket (choose GORE-TEX fabric to cope with the changeable weather on the plateau) 2. Spare clothes: Bring 1 more set of quick-drying underwear (replace it in time after hiking to avoid catching a cold), and it is recommended to bring 3 pairs of wool socks (moisture-absorbing and non-slip). 3. Shoe details: Hiking shoes need to be "broken in" for 3 days before departure (to avoid blisters), and a pair of lightweight camp shoes can be prepared (to change into during rest). II. Daily Necessities: Details Determine Experience ✅ Essential Supplements: 1. Sun protection enhancement: In addition to 50+ sunscreen, it is recommended to bring a physical sun protection hat (wide brim + adjustable rope to prevent strong winds) and sun protection sleeves (to avoid sunburn on arms when hiking). 2. Toiletry bag: Portable toiletries (some plateau accommodations do not provide them), and prepare wet wipes (for wiping sweat/cleaning when hiking) and hand sanitizer (for disinfection after using the toilet outdoors). 3. Rain gear selection: A raincoat is better than an umbrella when hiking (free your hands and prevent strong winds from overturning it), and choose a style with reflective strips (for safety at night). III. Medicines: Prevention First, Carry as Needed ✅ Key Reminders: 1. Anti-altitude sickness drugs: - Rhodiola rosea capsules are recommended to be taken 3 days in advance (to improve the body's oxygen-carrying capacity), and Gaoyuan'an can be prepared for acute altitude sickness (to relieve headaches and nausea). - Glucose oral solution (more convenient than powder, drink directly when hiking), oxygen cylinders (recommended to buy locally to avoid the trouble of air consignment). 2. Dispensing skills: Dispense medicines into small medicine boxes according to "daily doses" to avoid missed doses or carrying too much. 3. Special groups: Patients with high blood pressure/heart disease need to consult a doctor in advance, carry commonly used medicines and prepare English instructions (medical treatment in remote areas may require it). IV. Food: Lightweight + High Energy ✅ Preferred Recommendations: 1. Energy type: Dark chocolate (85% or more, anti-fatigue), nut energy bars (no added sugar, long-lasting energy supply), beef jerky (choose low-salt type to avoid thirst). 2. Filling type: Compressed biscuits (small size and high calories), freeze-dried fruits (supplement vitamins, good taste), you can bring 1-2 packs of pickles (supplement electrolytes, relieve loss of appetite). 3. Drinking water: Thermos cup filled with warm water (cold water is easy to cause gastrointestinal discomfort on the plateau), you can add electrolyte effervescent tablets (to prevent dehydration). V. Documents: Safe Storage + Backup ✅ Practical Tips: 1. Storage tools: Use a waterproof document set for ID card/passport, and then put it in a waist bag (close-fitting anti-theft). 2. Electronic backup: Take photos of documents with your mobile phone and save them in the album, and synchronize them to the cloud disk (you can quickly reissue them in case of loss). 3. Discount documents: Check the destination scenic spot discount policies in advance (such as some scenic spots in Tibet require a border defense certificate, whether the senior citizen card/student ID is universal). VI. Other Equipment: Detail Control Bonus Items ✅ Check for Omissions and Fill Vacancies: 1. Backpack system: - Choose a professional backpack system for backpacks (such as Osprey, Gregory, to reduce shoulder pressure), and choose an anti-theft waist bag (zipper concealed design). - Put a waterproof bag in the backpack (to pack clothes to prevent them from getting wet), and hang trekking poles on the outside (saving 30% of physical strength, especially downhill). 2. Sleeping equipment: In addition to sleeping bags, people with cleanliness habits can bring bed sheet dirt-proof bags (lightweight and easy to store), earplugs + eye masks (to cope with multi-person accommodation environments). 3. Electronic equipment: Choose a power bank with 20,000mAh or more (low temperature consumes power quickly), and bring a Type-C/Lightning 2-in-1 data cable (to reduce the burden of cables). VII. Packing Tips: Efficient Packing Without Stepping on Pitfalls 1. Suitcase zoning: - Upper layer: Commonly used items (power bank, documents, snacks) - Middle layer: Clothes (packed in compression bags to save 50% of space) - Bottom layer: Shoes (wrapped in shoe covers to avoid soiling clothes) 2. Carry-on bag checklist: - ID card, a small amount of cash (there may be no signal in remote areas), thermos cup, sunscreen, power bank, lightweight raincoat. Scenario-based Tips: Precautions for Hiking on the Plateau - When hiking: Slow down (avoid panting), rest for 10 minutes every hour, and replenish water and energy in time. - When staying: Avoid washing your hair and bathing on the first night (to prevent colds from causing altitude sickness), and turn on the humidifier in the room (the plateau is dry and prone to nosebleeds). - Environmental awareness: Take garbage with you (the plateau ecology is fragile), and do not pick plants/feed wild animals at will. Prepare according to this list, which can not only cope with the complex environment of the plateau, but also improve the comfort of the trip. I wish you a smooth journey and a safe arrival at every destination! 🌄
