You have seen the photo. Somebody on a narrow ridge, brilliant light, the whole of Snowdonia behind them. And you have thought, quietly, “could I do that?”
Here is how to know if a hike is too hard for you, and it takes about ten minutes at the kitchen table. Look up five things the photo cannot show you. The distance and height gain, how exposed the ground is, whether there is a way off partway round, how long it will honestly take you, and what the weather will be doing on the top rather than in the car park.
If those five stack up, go. If one of them does not, you have not failed anything. You have just found out something useful before you were standing on it.
Why can a route that looks fine in a photo be a serious day out?
Because a photograph is a single second of the best conditions anybody had all year.
Llanberis Mountain Rescue Team, whose patch includes some of the most photographed ground in Britain, put it well in a statement in September 2026. Talking about the images of Crib Goch that circulate online, they said: “What it doesn’t show is how intimidating that ridge can be in cloud, rain or strong winds.”
The same team was careful to say what the problem is not. “The mountains have not suddenly become more dangerous,” they said. “More people are visiting them, and the way routes are discovered and accessed has changed.”
That is a fair and generous description, and it is worth holding on to. Nobody is saying you should not want to go. They are saying the picture is missing the information you would need to decide.
What do the rescue figures say about inexperience?
Less than you might expect, and it is worth being precise about that.
None of the three UK services that publish figures records social media as a cause of anything. Mountain Rescue England and Wales, Scottish Mountain Rescue and the Lake District teams do not have a category for it, so anyone quoting you a percentage of callouts caused by Instagram has made it up.
What MREW does record is contributory factors, and in 2025 the two it logged most often were poor decision making or human error, 939 times, and inexperience of pursuit, 644 times. Both were recorded more often than weather.
Beyond the data, there are named people saying what they see. Mike Park, chief executive of MREW, told the Guardian in April 2025 that people are “tempted into risky locations by Instagram posts”, and described “a tendency to follow popular routes online without knowing the hazards and context”.
That last phrase is the whole article in five words. Hazards and context. The photo gives you neither, and everything below is about getting them back.
The five checks, before you commit
None of this needs a subscription or an app. It needs a map, a forecast and ten minutes.
1. Distance and ascent, converted into hours. Distance alone tells you almost nothing. Naismith’s Rule is the usual starting point, an hour for every 5km you cover plus an hour for every 600m you climb, and we have been through how to apply it honestly. Then add time for breaks, photographs, and the bit where you stand about deciding. If the number you get is bigger than the daylight you have, that is your answer.
2. Exposure, which is not the same as difficulty. Ask specifically whether any part of the route is a scramble, whether there is a drop on one or both sides, and how wide the ground actually is. A path can be technically easy and still be somewhere you would rather not be in wind. Guidebook descriptions and route notes will tell you this if you look for the words rather than the pictures.
3. Whether you can get off partway round. Look at the map for the points where you could cut the day short and drop into a valley. Some routes have several. Some ridges have essentially none once you commit, and that is a completely different kind of day.
4. The time you would have to turn around. Work backwards from when it gets dark, take an hour off for margin, and see whether the route still fits. Decide that number at home.
5. The weather on the top, not in the valley. Use a mountain forecast rather than a town one. Look at wind speed at summit level in particular, because wind is the thing that turns an easy ridge into a hard one, and it is invisible in every photograph ever taken.

What a photo is not telling you
It is worth running through this consciously, because the gap is bigger than it feels.
A photo does not show the wind. It does not show what the ground was like an hour earlier or an hour later. It does not show the queue at the narrow bit on a bank holiday, or how long the descent took, or the fact that the photographer had done it four times before.
It usually does not show the weather anywhere except in that one frame.
And it never shows the decision the person made two hours earlier about whether to keep going, which is the decision that actually determined how the day went.
What if the honest answer is “not yet”?
Then you have done the thing properly, and it is worth saying clearly that this is not a failure.
Every walker who is comfortable on hard ground was once not comfortable on it. The route is not going anywhere. Ridges are famously patient.
What changes “not yet” into “yes” is ordinary and unglamorous. Do the same kind of ground at a smaller scale. Get properly confident with a map so that cloud is an inconvenience rather than an emergency. Go out with someone who has done it. Build up your honest walking pace so your timings stop being guesses.
And if you are in the middle of working out where you actually are on that curve, our article on whether you are ready to walk in the hills without a group is the companion piece to this one. That one asks whether you are ready to go alone. This one asks whether this particular route is right for you, which is a different question with a different answer.
It is also worth knowing that fine weather is not the safety net people assume it is. We went through why most Scottish mountain rescues happen in good weather using the Scottish figures, and it is a useful corrective to a sunny forecast.
Frequently Asked Questions
How do you know if a hike is too hard for you?
Check five things before you go. Convert the distance and ascent into hours and compare that with your daylight. Find out whether any of it is exposed or involves scrambling. Look on the map for places you could cut the day short. Decide a turnaround time. And read the summit forecast rather than the valley one. If any of those does not stack up, the route is not right for you today.
Is social media really causing more mountain rescue callouts?
None of the three UK services that publish figures records social media as a cause, so there is no percentage to quote and you should be sceptical of anyone who gives you one. What exists is senior rescuers saying what they see. Mike Park of Mountain Rescue England and Wales has described people being “tempted into risky locations by Instagram posts”, and Llanberis Mountain Rescue Team says “the way routes are discovered and accessed has changed”.
How long will a hill walk actually take me?
Naismith’s Rule is the common starting point, an hour for every 5km plus an hour for every 600m of ascent, then extra for breaks and photographs. Treat that as a first estimate and correct it against your own real pace on walks you have already done. Most people walk slower than they think, particularly in descent and particularly on rough ground.
What does “exposed” mean on a walking route?
It means there is a significant drop close to where you are walking, so a slip would have serious consequences, regardless of how technically easy the ground is. Exposure is about how a route feels and what a mistake would cost, not how hard the moves are. Many people are perfectly capable of the movement required and still find exposure genuinely unpleasant, which is normal and worth knowing about yourself before you commit.
Should I turn back if I am not sure?
Yes, and you would be in good company. The Lake District mountain rescue teams put the same line in every annual report: “it is no disgrace to turn back if you are not certain.” Turning back is a decision that keeps all your options open. Carrying on because you feel you ought to is the one that closes them.
Wanting to Go Is the Right Instinct
None of this is an argument against ambition. The photo did its job, which was to make you want to be somewhere brilliant.
All the five checks do is fill in what the photo left out, so that when you go, you go on purpose, on a day that suits the route, with a plan for the bit where it stops being fun.
If you are not sure where your skills actually sit at the moment, our free navigation quiz takes a few minutes and tells you straight, then points you at what to work on.
Pick the route you have been thinking about and run the five checks on it tonight. Whatever the answer turns out to be, you will know something you did not know this morning.
