Top 10 Mistakes People Make When Trekking Abroad (And How to Avoid Them)

Trekking abroad is one of the most rewarding experiences you can have — new landscapes, new cultures, and new challenges all rolled into one. But let’s be honest… it’s also easy to get caught out.

From poor prep to gear fails and altitude issues, these are the top 10 mistakes I see people make on international treks — and how you can avoid every single one of them.

1. Underestimating the Altitude

The mistake: “I’m pretty fit — I’ll be fine.”

Why it matters: Fitness doesn’t protect you from altitude sickness. Trekking at 3,000m+ is a different game altogether.

Avoid it: Choose itineraries with built-in acclimatisation days. Walk slowly. Stay hydrated. Know the signs of altitude sickness — and don’t push through them.

2. Buying New Boots the Week Before

The mistake: Rocking up in shiny new hiking boots.

Why it matters: Blisters. Bruised toes. Limping to the finish line.

Avoid it: Break your boots in properly with multiple long walks before your trip. Wear the same socks you’ll use on the trek.

3. Overpacking (Or Packing the Wrong Stuff)

The mistake: Bringing too much — or the wrong kit.

Why it matters: You’re either hauling dead weight or missing key essentials.

Avoid it: Use a tried-and-tested packing list (I’ve got one!). Prioritise lightweight layers, waterproofs, and reliable gear over gadgets and extras

4. Not Training on Hills

The mistake: Hitting the gym but skipping the hills.

Why it matters: Trekking is all about time on your feet, not time on the treadmill.

Avoid it: Get outside. Train on real terrain with your pack. Try back-to-back days and aim for elevation gain, not just distance.

5. Ignoring Mental Preparation

The mistake: Focusing only on the physical side.

Why it matters: Trekking can be tough — long days, basic food, no signal, unpredictable weather. Your mindset makes all the difference.

Avoid it: Visualise challenges. Train in poor weather. Learn to embrace discomfort — it’s part of the adventure.

6. Not Having Travel Insurance That Covers Altitude

The mistake: Buying a cheap policy without reading the fine print.

Why it matters: Many policies don’t cover trekking over 4,000m — and definitely not helicopter evacuation.

Avoid it: Make sure your insurance specifically includes high-altitude trekking, medical evacuation, and trip cancellation.

7. Skipping Pre-Trip Conditioning

The mistake: Relying on “natural fitness.”

Why it matters: Even fit people struggle without targeted preparation.

Avoid it: Follow a structured training plan that includes hiking, strength, and cardio — ideally starting 8–12 weeks before you go.

8. Forgetting to Pack for All Weather

The mistake: Only packing for sun (or only for cold).

Why it matters: Weather in the mountains is unpredictable and can change fast.

Avoid it: Use a layering system. Always pack a waterproof shell, warm jacket, gloves and a buff — even on “summer” treks.

9. Not Staying Hydrated

The mistake: Drinking too little, too late.

Why it matters: Dehydration increases your risk of altitude sickness and fatigue.

Avoid it: Drink 3–4 litres a day while trekking. Use water purification tablets and carry easy-access bottles or a hydration bladder.

10. Not Asking Enough Questions Before Booking

The mistake: Picking a company based on price alone.

Why it matters: Not all trek operators are created equal — and some cut corners on safety, pay, or support.

Avoid it: Ask about group size, acclimatisation, guide experience, porter treatment, inclusions and cancellation policies. If in doubt — ask more.

Final Thoughts

Trekking abroad is unforgettable — but only if you show up prepared. A little planning goes a long way towards a safer, smoother, and more enjoyable adventure.

Avoid these mistakes, and you’ll set yourself up for success — whether you’re heading to Toubkal, Kilimanjaro, Everest Base Camp or beyond.
