What's in a Guide's Backpack? Practical Tips to Avoid Mistakes

Preparing a backpack for a summer trek is not just about deciding what to bring, but understanding how much weight you are willing to manage, what will really be needed during the day, and how to optimize every choice.

A well-organized backpack can completely transform the experience, making the journey smoother and more efficient.The first point to consider is the overall weight. For a day hike, a balanced backpack weighs between 4 and 7 kg. If it’s a multi-day trek with shelter support, the realistic weight increases to between 6 and 9 kg. Exceeding these values often means carrying unnecessary items, which will be felt especially during long ascents.

Water is the most important element to manage. In summer, the need increases significantly, especially with considerable elevation changes and high temperatures. A concrete estimate is about one liter every two hours of walking. This means that for a five or six-hour outing, you need to start with at least two or three liters. If there are sources along the way, you can reduce the initial load by bringing a filter or purification tablets. Drinking little and rarely is one of the most common mistakes, while the ideal is to maintain constant hydration throughout the day.

Food must also be chosen carefully. On a trekking day, about 400 to 600 grams of well-selected food is sufficient. A simple sandwich, a few energy bars, and a small amount of dried fruit cover the needs without weighing you down. On multi-day treks, it’s important to think in terms of calories, aiming to reach at least 2000 to 3000 calories a day through light and compact foods. Dry foods like couscous, ready rice, or noodles represent a practical and efficient solution.

Clothing follows the layering logic but should be reduced to the essentials. During the hike, you generally wear a technical shirt and a light layer, while in the backpack, it’s essential to have a waterproof jacket and a thermal layer. Even in the height of summer, above 2500 or 3000 meters, temperatures can change rapidly, going from warm conditions to decidedly colder situations.

A warm layer, a hat, and a neck gaiter are items that take up little space but can make a big difference. Safety should never be overlooked. There is a minimum kit that should always be present in the backpack, regardless of the duration of the hike. This includes a small first aid kit, a headlamp, a charged phone, an external battery, a map or GPS track, and an emergency thermal blanket. This is a lightweight load, generally under one kilogram, but it holds enormous value in case of unforeseen events.

Shoes (and socks) deserve a separate discussion, and we will dedicate an article to them. When tackling multi-day treks, backpack organization becomes even more important. Every element must be chosen carefully, prioritizing lightness and functionality.

An essential change of clothes, a minimal hygiene kit, and a sleeping bag liner are generally sufficient if you are sleeping in a shelter. In these cases, a well-optimized backpack stays between 7 and 9 kg, allowing you to tackle consecutive days without accumulating excessive fatigue. One of the most common mistakes is bringing items "just in case." Excess clothing, less useful accessories, or unnecessary equipment end up weighing down the backpack without offering real benefits. A good rule is to ask yourself, for each item, when it will be used. If there isn’t a clear answer, it’s probably not essential. The ideal balance lies in finding a synthesis between lightness and safety.

A backpack that is too light but incomplete can expose you to risks, while one that is too heavy makes the journey inefficient and more tiring. With experience, you learn to progressively reduce the superfluous, keeping only what is truly needed. Summer trekking, whether for a day or multiple days, does not require complex equipment, but a good planning ability. Having the right elements with you at the right time allows for greater safety and a more conscious experience.

Ultimately, it’s not the quantity of items in the backpack that makes the difference, but the quality of the choices. An essential, well-thought-out, and tailored equipment is the foundation for truly enjoying the mountains, without distractions and without unnecessary weights.
