How to Prepare for a UK Mountain Hike: 6 Essential Things I Always Do

Heading off for a hike in the mountains of the UK is one of the most rewarding and incredible things you can do. Not only does it provide a proper physical workout, it is great for your mental health, gives you a huge sense of achievement, epic views, and memories that will last a lifetime.

Although they are not the highest in the world, our mountains in the UK are unpredictable, exposed and, if you get complacent, unforgiving, especially if you head out unprepared.

Over the years I have developed a simple routine that I follow before every single hike. It is nothing fancy, just common sense and experience. It keeps me safer, makes the day more enjoyable, and massively reduces the chances of something going wrong.

Whether I am heading into Snowdonia, the Lake District, the Brecon Beacons or further north into Scotland, these six things never change. So if you are heading into the mountains, you should probably be doing them too.

 

1. Check and Monitor the Weather

First thing I do is check the weather for the specific mountain or mountain range I want to hike.

Why? Well, if the weather is rubbish, I will not bother heading into the mountains.

I hike first and foremost for enjoyment, and the views are a big part of that. I’m not a sadist, so I would rather not spend the day hiking in bad weather to see sod all.

If I just want to spend time in nature or get outside, there are plenty of lower level alternatives if the mountains are going to be miserable or dangerous. And if I just want a workout, I will head to the gym or go for a run.

You also have to remember, you are not just putting yourself at risk if you head out in bad weather. If something does go wrong, it is Mountain Rescue, who are unpaid volunteers, that have to come out and rescue you. That means they are putting their lives at risk.

Below are four things I look for in a forecast. These have the biggest impact on both safety and enjoyment and will also dictate what clothing and equipment I need to bring.

  • Visibility

  • Chance of precipitation

  • Wind speed and direction

  • Feels like temperature

I usually check and monitor the weather several days before a hike, right up until I set off. Checking early also gives you an idea of the ground conditions, whether it will be wet, icy or snow covered.

I check multiple sites and there are three in particular I use.

 

MWIS - Mountain Weather Information Service

This is usually my first stop as it gives the forecasts for 10 mountainous regions of the UK. So I can get an overview for  the weather in an certain area. It is just a website, but you can save it to your home screen. The MWIS offers

  • Three-day forecasts updated daily

  • Written specifically with mountain users in mind

  • Explains the impact of the weather the hiker

  • Simple and easy to read

  • Includes helpful graphics

https://www.mwis.org.uk/

 

Met Office

I then head to the Met Office to cross check the forecast. They are the official weather provider of the UK, so tend to be the ‘most’ accurate’.  

  • Allows you to search specific peaks and locations

  • Clear graphics and breakdowns

  • Five-to-seven-day outlook

  • App and website available

 

Windy

Finally, I will use windy, which is a worldwide animated weather map, to check wind speed and Direction

  • Free to use: with both app and website

  • I mainly use it for wind, but it shows lots of other options (Weather, waves)

  • Easy to understand as it displays wind speed with colour and direction with arrows

  • Forecasts up to six days in advance

It is great for exposed terrain and judging ridge days. It also helps me decide whether I can realistically fly my drone.

I sometimes use Mountain Forecast as well. It shows forecasts for specific peaks and different elevations, and it is useful outside the UK. However, I have found it can occasionally differ quite a lot from MWIS and the Met Office.

Remember the weather can change quickly, especially in the mountains. Keep checking up until you set off on your hike

  • Do not be afraid to change plans or cancel. The mountains aren’t going anywhere

  • Do not treat forecasts as gospel. They can be wrong.

  • Always pack essentials as conditions in the mountains can change rapidly. Its always better to have it and not need it than need it and not have it.

2. Plot and Research My Route

I never just turn up and start hiking

First, I Google the route. There is usually a blog, a vlog or at least some kind of trip report out there. This gives me a better idea of what to expect and will often provide all the key information I am looking for; If it is a technical hike, I also look for photos and videos so I can understand how exposed or difficult certain sections are, and judge whether it is suitable for me and whoever I am hiking with.

Key things to know

  • Distance

  • Elevation gain / ascent

  • Route profile

  • Terrain and technical sections

  • Start and finish point

  • Parking situation

Once I know this, alongside the weather forecast, I can realistically gauge how long it will take.

Apps and websites give predicted durations, but that depends heavily on your fitness level, your group’s fitness, experience and how confident you are on certain terrain.

A technical scramble up steep ground will take much longer than a steady walk over rolling hills.

Years in the hills mean I usually have a good idea how long hikes will take me. If you are newer to hiking, always give yourself more time than you think you need.

Also factor in the drive and parking. Hiking has become far more popular in the UK, especially in summer. Parking around hotspots can be difficult. You might spend longer than expected finding a space or have to park further away. Both add time and distance which will eat into your hiking time.

What I use to plot my routes

I use OS Maps Premium Subscription which costs £34.99 per year as of early 2026, or £6.99 per month. I use OS as they are the official map provider of the UK, and I have found them to be the most accurate and detailed of the options in the UK

  • Have both a Website and app, which are easy to use

  • Three base map options to plot my routes using

  • Snap to path feature allows for easy route plotting

  • I can plot the route on my computer and it instantly available on my phone

  • 3D fly through feature allows me to preview the route

  • Ability to print maps to scale as a physical backup

  • I can also download routes and map areas for offline use

I have used other apps like AllTrails and Komoot. They are not bad, but they do not give me the same level of confidence and detail as OS Maps.

 

3. Download the Route for Offline Use

Once my route is plotted, I download it for offline use. Remember to do this the night before because signal in the mountains is patchy at best

It’s one of the main reasons I use OS Maps as it allows you to download both the route and the surrounding area.

I also like to use my Garmin alongside my phone for navigation. I prefer doing this as it means I can hike hands free, and save my phone battery. However, I will always keep the route on my phone as a backup.

To do this, I export the route from OS Maps, upload and save it to Garmin Connect as a course, and then send it to my device.

 

4. Put Safety Measures in Place

Before I go on any hike, I always let someone know the following things so I do not ending up like the bloke from 127 Hours.';

  • Where I am going

  • What hike I am doing and which mountains I am climbing

  • Roughly how long I expect to be

That way, if something drastic does go wrong and they do not hear from me, they can pass that information on to the relevant authorities.

In addition, there are several key items I always carry year round when I head into the mountains. Remember, forecasts can be wrong and conditions can change quickly. Always better to have it and not need it.

If something does go wrong and you contact Mountain Rescue, they cannot teleport to you. Helicopters are only used in the most serious situations. It will usually take several hours for a team to reach you. While you wait, staying warm and dry is critical.

Satellite Messaging

Having a way to contact both the authorities and loved ones when you do not have signal is a big step up in safety. I have the Garmin inReach Messenger Plus

  • SOS alerts to a 24 hour emergency response centre

  • Uses the global Iridium satellite network

  • Allows two way messaging, including images and voice notes

  • Location sharing and tracking

  • Around 28 days battery life depending on use

  • Costs roughly £350 plus a monthly subscription

You cannot really put a price on safety, but not everyone will be able to afford it, especially if you are new to hiking.

You can also now send satellite emergency messages via newer iPhones in supported regions, provided you have a clear view of the sky and horizon. This is available on models from the iPhone 14 range onwards, running recent iOS versions

 

5. Layout and pack the correct clothing and kit

I always get my kit ready and pack my bag the night before. That way I know I have everything I need and it avoids a rushed morning. I also make sure all my electronics are fully charged. What I pack depends on the weather, length of the hike, season and terrain.

However no matter the weather or season, I always carry the following. Even if the forecast looks perfect, conditions can change quickly in the mountains.

  • Backpack

  • Waterproof outer shell

  • Extra layers, insulated jacket and mid layer

  • Gloves and hat or buff, thickness depending on conditions

  • Power bank and charging cable

  • Headtorch

  • Water and snacks

  • Emergency bivvy bag

  • My phone

I will also carry additional items depending on the season. For example, in winter or colder conditions I might also take:

  • Additional warm layers

  • Walking poles

  • Spikes or crampons

  • Goggles

  • Ice axe,

Winter kit is not something to guess with. If conditions require it, you need the right equipment and the knowledge to use it safely. Packing properly the night before removes stress and reduces the chances of forgetting something important.

 

6. Prepare Food, Snacks and Hydration

The chance to eat calories guilt free with epic views is one of the best things about hiking and I never miss that opportunity.

Fuel and hydration are key to keeping energy levels up in the hills. It is also a morale boost knowing you have good snacks waiting in your bag when you reach the summit, or if you need m a little pick me up.

For shorter hikes under three hours, I usually take snacks and eat something more substantial before and after. I love a pastry, sweets and chocolate. Sausage rolls, pain au chocolat, Clif bars and Snickers are personal favourites.

For anything longer, I will take a more substantial meal. Wraps and sandwiches are my go to. They are easy to carry and easy to eat on the move.

Making them the night before means you are not rushing in the morning and you will not forget them, leaving you hangry halfway up a mountain.

Starting hydrated is also key. I usually drink 500 to 750 ml before setting off, then carry between 500 ml and 2 litres depending on the hike. As I set off well hydrated, I often find myself not drinking hardly anything, Again, better to have it and not need it than need it and not have it.

Sometimes I will carry a fizzy drink, or if I am heading out for a sunset, even a cider.

In winter, I like to take a thermos flask with a hot drink. It gives you something to look forward to and boosts morale while helping keep you warm.

 

    • Know and plan the Route: Use proper hiking app (I use and recommend OS Maps) and have the route downloaded for offline use

    • Check the Weather: Always check the weather forecast for the specific peaks and mountain ranges you are planning on hiking. I use MWIS and Met Office

    • Start Early: Give yourself plenty of daylight to complete the hike.

    • Know Your Limits: This hike requires a good level of fitness and a head for heights.

    • Group Up: If possible, hike with others or consider hiring a local guide for extra safety

    • Wear and carry the correct kit: see below

  • The correct kit and equipment are essential when hiking in Scotland.

    • Sturdy hiking boots with good grip

    • Waterproof jacket and overtrousers

    • A layering system (wear/carry a minimum of 3 top half layers, with a 4th in winter)

    • GPS device with the route downloaded (or Map and compass)

    • Power bank and charging cable

    • Headtorch + First aid kit

    • Plenty of fluids and high-energy snacks

    • Gloves and a hat for cooler conditions

    If it’s winter then crampons, micro spikes, and an ice axe(s) are essential alongside extra clothing. I’d also recommend walking poles and ski goggles.

Final Thoughts

So there we go, the six things I do before every hike. None of this is complicated, It is just common sense and a bit of experience.

Half the problems people run into in the hills could have been avoided with 30 minutes of planning the night before. Check the weather properly. Know and download your route. Tell someone where you are going. And carry the correct clothing and kit.

It’s not only going to make hiking in the mountains much safer, but also a lot more enjoyable and stress free. So you can keep on doing it and reaping the benefits of being in the outdoors for years to come.

Always remember, it is better to have it and not need it than need it and not have it.

If in doubt, turn around or give it a miss. The mountains will always be there, and no hike is worth risking your life, or someone else’s, for.
