Ensure the shoulder straps are well padded to prevent any discomfort during your long walks in the mountains. A chest or waist strap helps to distribute the weight of your gear more evenly across your body. You can find many great options by checking out these Interlaken hiking gear tips before you shop.

Many modern day packs also come with a built-in rain cover stored in a small bottom pocket. Swiss mountain weather can change very quickly, so having a waterproof cover for your bag is very useful. It keeps your spare clothes and electronics dry even during a sudden afternoon rain shower in the Alps.

Hydration and Nutrition Essentials

Staying hydrated is vital when you are walking at higher altitudes in the beautiful Swiss Alps. You should always carry at least 1.5 liters of water for a full day of walking activity. Mountain air is often very dry, which means your body will lose moisture faster than at sea level.

Interlaken provides many public fountains where you can refill your bottle with fresh mountain water for free. These fountains are clearly marked and the water is usually very cold and delicious to drink. Carrying a reusable bottle is better for the environment and saves you money during your Swiss vacation.

Pack high-energy snacks like nuts, dried fruits, and local Swiss chocolate to keep your energy levels high. You should eat small amounts of food frequently rather than having one very large meal during your walk. This approach helps you maintain a steady pace as you explore the many scenic walks in Interlaken.

Weather Protection and Layering

The mountain weather during the 2026 season can change from sunny to rainy in just a few minutes. You must always pack a lightweight waterproof jacket even if the morning sky looks perfectly clear and blue. This outer layer also protects you from cold winds when you reach higher elevations or ridge lines.

It is very helpful to learn about layering clothes for changing Interlaken mountain weather before you start your journey. A moisture-wicking base layer will keep you dry and comfortable while you are climbing the steep trails. Avoid wearing cotton clothing because it stays wet and can make you feel very cold when you stop.

Temperatures can drop significantly as you gain elevation on trails like the Harder Kulm or Schynige Platte. Always pack a light fleece or a thin down jacket in your day pack for extra warmth. You will be glad you have it when you stop to enjoy the view at the summit.

Safety Gear and Navigation Tools

Safety should always be your top priority when exploring the trails around the Interlaken and Jungfrau region. You should carry a basic first aid kit that includes blister plasters and some simple antiseptic wipes. Small injuries can happen on rocky paths, so being prepared helps you continue your walk without pain.

It is also important to follow these sun protection tips for high altitude to avoid getting a painful sunburn. The sun is much stronger in the mountains than it is at sea level during the summer months. Pack a high-SPF sunscreen, a pair of quality sunglasses, and a wide-brimmed hat in your bag.

Download offline maps to your phone before you leave your hotel in Interlaken town for the day. Cell phone service can be weak in deep valleys or behind large mountain peaks in the Bernese Oberland. A portable power bank is also a smart addition to keep your phone charged for navigation and photos.

Local Comfort Items for 2026

Many local walkers use trekking poles to help with the steep descents found on many Interlaken trails. These poles reduce the impact on your knees and provide better balance on uneven or rocky ground. You can easily strap them to the outside of your backpack when you are not using them.

Carrying a small amount of cash in Swiss Francs is useful for buying snacks at remote mountain huts. Some smaller alpine farms only accept cash for their fresh cheese, milk, or homemade fruit cakes. These mountain treats are a highlight of any walking trip in the Interlaken area during 2026.

Include a small sit pad or a lightweight towel to sit on during your lunch breaks. The ground or wooden benches can often be damp or cold, especially in the early morning hours. A dry place to sit makes your rest stops much more relaxing and enjoyable for everyone.
