Survival Guide: The 3 Items I’d Take if I Were Isolated on an Island

Posted by Li Weisi on

Imagine yourself alone on a deserted island, with nothing but the vast ocean around you and a few palm trees swaying in the breeze. You have no way of contacting the outside world, and your survival depends entirely on the tools you have with you. While many might think of bringing high-tech gadgets or luxury items, in reality, survival in such a scenario comes down to the basics: food, water, shelter, and safety.

The challenge is to select just three items—nothing more, nothing less—that could make the difference between surviving for a few days or a few weeks. After thinking it through, I’ve narrowed down the three most essential items I would bring to ensure survival, comfort, and a higher chance of being rescued. These include a multi-tool, a fire starter kit, and a water filtration system, but there’s one more item that would be absolutely crucial for my survival on the island: water shoes.

Let’s dive into the reasons why these four items are indispensable in a survival scenario.

1. Multi-Tool (Swiss Army Knife)

When it comes to versatility, the multi-tool is unrivaled. A Swiss Army knife or a similar all-in-one tool can perform a variety of functions, making it indispensable when you’re stranded on an island. The multi-tool typically includes a knife, screwdriver, can opener, tweezers, scissors, and sometimes a small saw, all within a single, compact device.

Here’s why it’s vital:

  • Food Procurement: The sharp blade of the multi-tool is invaluable for hunting, fishing, and preparing food. Whether it's gutting fish, cutting fruit, or preparing makeshift traps for small animals, the knife is essential. The saw can also help you cut branches or wood for shelter or firewood.

  • Shelter Building: In a survival situation, you need to build a shelter to protect yourself from the elements. The multi-tool’s knife and saw can help you cut down branches, strip bark, and create the framework for a makeshift shelter. You can also use it to cut vines and tie materials together.

  • Self-Defense and Protection: While you likely won’t encounter dangerous animals on a small island, there is always the possibility of snakes, insects, or even territorial animals. A sharp blade can be used for self-defense in a worst-case scenario.

  • Other Uses: Beyond survival basics, a multi-tool can be used to make small repairs, such as fixing broken gear or creating new tools to assist with food gathering or shelter building. It’s also a lifesaver in medical emergencies, as you can sterilize and use it to cut cloth for bandages, splints, or other makeshift first aid needs.

A multi-tool is truly the Swiss army knife (pun intended) of survival, providing multiple functionalities in a small, portable package. It will become your lifeline in nearly every aspect of island life.

2. Fire Starter Kit (Lighter and Flint)

Fire is arguably the most important element for survival on a deserted island. Not only does it provide warmth and light, but it is also essential for cooking food, purifying water, and signaling for help. Without fire, survival becomes significantly more difficult, and exposure to the elements or the inability to cook could result in illness or even death.

Why would I choose a fire starter kit over traditional matches? A fire starter kit typically includes a flint, which can be used to create sparks, and a lighter to ensure you can start a fire more easily and quickly in the initial stages. Here’s why these are essential:

  • Warmth and Cooking: Fire allows you to cook food, which is necessary for nutrition and energy. Cooking also helps to eliminate bacteria and parasites in your food. A fire provides warmth during cooler nights or rainy days, which can help prevent hypothermia or just general discomfort.

  • Water Purification: Boiling water is one of the most effective ways to purify it. In a survival situation, you must ensure that any water you drink is free from pathogens, bacteria, and parasites. A fire starter allows you to boil water from natural sources such as rivers or streams, ensuring safe hydration.

  • Signal for Rescue: Fire acts as a beacon for passing ships or rescue teams. It’s visible from a distance, especially at night, and can help alert others to your location. Smoke signals can also be used during the day as a distress call.

  • Morale Boost: On a psychological level, fire can be incredibly comforting. Its warmth and light provide a sense of safety, comfort, and security. It can help maintain hope and focus during the long wait for rescue.

With a fire starter kit, you’re ensuring that you have a reliable method to maintain your body temperature, purify water, cook food, and potentially signal for rescue. In a survival situation, fire is a critical part of staying alive.

3. Water Filtration System (Portable Water Filter or Purification Tablets)

Water is a fundamental necessity for survival. You can survive for weeks without food, but only a few days without water. If you’re stranded on an island, access to fresh, clean water is essential for your survival. While the ocean may surround you, drinking seawater is not an option—it’s full of salt, which will only dehydrate you further.

A water filtration system such as a portable filter or water purification tablets would be my third essential item. Here’s why it’s a lifesaver:

  • Safe Drinking Water: Natural water sources, like streams or rivers, may look clean, but they are often contaminated with bacteria, parasites, and other harmful microorganisms. A portable water filter can remove these contaminants, making water safe to drink. Some advanced filters can even eliminate harmful chemicals and toxins from the water.

  • Convenience and Portability: Water filters are compact and lightweight, making them easy to carry and store. Many modern portable filters can be used directly from a stream or river, allowing you to drink water on the go. If you don’t have access to a filter, water purification tablets are also a lightweight and effective option for sterilizing water.

  • Long-Term Hydration: In a survival situation, you must have a reliable and sustainable source of clean water. A filtration system ensures that you can purify water from natural sources, providing the hydration needed to keep you alive and healthy.

Staying hydrated is key to survival, and with a water filtration system, you’ll ensure that you have access to safe water at all times. This is one of the most important items you can have on a deserted island.

4. Water Shoes

You may not immediately think of water shoes as a survival necessity, but in an island environment, they are absolutely crucial. Whether you are walking along rocky shorelines, wading through streams, or exploring the beaches, your feet will be exposed to a variety of potentially harmful conditions. Water shoes would be my fourth essential item for a number of reasons:

  • Protection from Sharp Objects: Beaches and shorelines are often littered with sharp rocks, coral, or debris that could injure your feet. Water shoes provide a protective barrier against cuts, scrapes, or puncture wounds, which are common when navigating rough, uneven terrain.

  • Comfort for Long Walks: Since you’ll likely be exploring the island to search for food, fresh water, or firewood, comfortable footwear will help you move more easily. Traditional shoes or sandals may not be as durable or comfortable in the water, whereas water shoes are designed to dry quickly and allow for maximum flexibility.

  • Prevention of Infections: Walking barefoot on a deserted island exposes your feet to bacteria, fungi, and parasites that can cause infections. Water shoes provide a layer of protection, reducing the risk of these kinds of infections while also providing comfort and support.

  • Efficient Movement in Water: If you need to wade through rivers or swim between islands, water shoes will help you maintain your footing and provide better traction in slippery or muddy environments. They will allow you to move more confidently through various terrains, both on land and in the water.

While water shoes might not seem like a traditional "survival" tool, they offer critical protection and support in a wet, rugged environment.

Conclusion

If I were isolated on an island, the three most essential items I would bring are a multi-tool, a fire starter kit, and a water filtration system. Together, these tools would cover the essentials for food, water, warmth, shelter, and safety. However, after further reflection, I would also add water shoes to my list. They provide essential protection and comfort when navigating the often harsh terrain of an island, ensuring that my feet remain in good condition for the journey ahead.

In survival situations, every item should serve multiple purposes, and these four items—multi-tool, fire starter, water filter, and water shoes—would provide the best chance of not just surviving, but thriving in an island isolation.
