Hiking First Aid Kit: Checklist for Hikers + Backpackers

A first aid kit is one of hiking’s Ten Essentials. The first thing I learned as a Wilderness First Responder is that in the outdoors, preparation is key. Whether you are a seasoned summiter or a daily stroller, carrying a first aid kit is essential for the safety of you and others. Here is a checklist, including some tips, for your hiking first aid kit.

The best hiking first aid kit checklist

Pre-Packaged First Aid Kit vs. DIY

Pre-packaged first aid kits like the Mountain Series Hiker Medical Kit and Ultralight Adventure Medical Kits provide a great foundation for your first hiking medical kit. Each is equipped with carefully selected tools and supplies to keep you and a friend equipped for most small adventures. Each pre-packaged kit, however, is different, and it is important to tailor each first aid kit depending on your adventure. That being said, we recommend that everyone should have a DIY first aid kit. Here is how:

How to build your own first aid kit for hiking

Building your first aid kit can be a little daunting. What if I pack too much? What if I forget something? What if it is my first hike ever and I have no idea what I will need?

Have no fear. We are here to help! Here is a step by step guide on how to build your very own first aid kit for hiking.

Think: SLARS

There are four important things to consider before you create your first aid kit. You can remember them by the acronym “SLARS.”

1) Size of Group

Are you building a personal first aid kit or planning for a group hike? The group size will determine the number of supplies you need.

2) Length of Trip

This determines the same thing as number 1 – in case of a backcountry accident, you will likely not have close access to a pharmacy. Because of this, it is imperative that you have enough medical provisions in case you need to reapply gauze and/or provide more medicine.

3) Activity

While this is a guide to building first aid kits for hiking, it is likely your trips will vary widely from our other readers. As we know, each hike is different – that’s what we love about it! However, because of the variations of hiking trips and environments, it is important to personalize your first aid kit for specific issues you may run into. Are you prepping for a flat day hike or an exposed, 14er scramble? If you are prepping for the 14er, a Sam splint is a good precaution for a potential broken bone or sprained ankle from a fall. If you are planning a first aid kit for routine hikes, the splint might be an overkill.

4) Risk

Risk falls under the activity section but is more focused on the environmental factors you will face. For example, if you plan on hiking in an area known for poison ivy (such as the east coast and midwest) and/or ticks, consider carrying a poison ivy treatment like the Tecnu Srub and/or a tick-specific tool like the Tick Key to your first aid kit.

5) Special Needs

Whether you are making a hiking kit for a group or yourself, always ensure you carry your personal medications whether for daily or emergency use. It is never a bad idea to carry extras. If you are planning a group hiking first aid kit, make sure everyone brings their personal medications. If you are in charge of medical care and the group members feel comfortable, it is always good to know their relevant medical history like allergies and/or respiratory issues.

First Aid Kit for Ultralight Hiking

It is critical to never sacrifice preparation and safety for weight. Always keep in mind the SLARS acronym we listed above. However, if you are a stubborn ultralight hiker looking to keep weight low, we have broken down the hiking checklist to the most essential items.

Essentials for an Ultralight First Aid Kit:

  • Gauze pads (x2): Important to stop bleeding and keep an injury clean from bacteria and dirt. These are important to prevent infection.
  • Antiseptic wipes (x4): Also important for preventing infection, antiseptic wipes help clean up wounds and the area surrounding them.
  • Bandaids (4): Helpful to cover up small scratches, cuts, and blisters.
  • Butterfly Bandages (4): Used to close deeper lacerations when stitches are unavailable.
  • Multipurpose Knife (1): Used for everything and should include tweezers.
  • Imodium or loperamide (4): Diarrheal medication
  • Acetaminophen/Ibuprofen (4): Help relieve pain, reduce inflammation, and treat fever.
  • Moleskin: Protect your feet from blisters and hot spots. This can make or break your trip.
  • Duct tape strips: Can be used for everything. Especially helpful to fix torn gear and keep bandaids/moleskin in place.

    For Ladies:
  • Extra tampons, pads, diva cup: You never know when mother nature will hit you. Always bring spares!

First Aid Training

Despite the wide range of first-aid backcountry handbooks, training in first aid is always a great idea to stay prepared and safe before an outdoor adventure. Basic medical training will help you conquer the initial shocks of a medical emergency and be more prepared for any incident. There are many first-aid courses including through the REI Outdoor School and American Red Cross. Classes through REI will be more outdoor adventure-focused.
