Tackle the highest mountain in England and Wales under a blanket of the night sky. Trekking Snowdon at 1,085metres during the daylight forms a great challenge, but by using your head torch to light your way and with the moon as your back drop, the summit brings another huge sense of achievement to such an iconic feat. Seeing the sunrise across Snowdonia National Park will be a memory to cherish for a lifetime! Upon your descent you will enjoy the awe-inspiring mountain landscape views and be impressed with the distance you covered under a starry sky.

Day 1

Day 1: Arrive in Llanberis in the late afternoon or early evening to allow time to meet the team, have a pre-trek briefing and get some rest prior to the late night trek ahead. 

Day 2

Following a quick cat-nap you will check back in with your Mountain Leader at 1am on the morning of Sunday 26th May at the Snowdon Railway Station (Llanberis, Caernarfon LL55 4TY). You’ll then switch on your head torch and set foot along the trail to the summit of Snowdon. Accompanied by your qualified Mountain Leader/s you will climb in teams on the Llanberis Path, the easiest hiking route to the summit of Wales’ highest mountain. After a tough climb by moonlight, you will reach the summit of Snowdon and take in the fantastic mountain range scenery as the sun rises. There’s plenty of time to take some group photos to celebrate the success of your summit achievement before descending back down via the Llanberis Path to Llanberis.

Adventurous Ewe reserves the right to change the route or itinerary for safety reasons should local conditions dictate.

Approx 7-8 walking.

Essential Information

Level of difficulty
Medium to Tough
The Snowdon by Night Challenge is graded as medium to tough depending on weather conditions. This is the ideal event for participants who are of an adventurous spirit and an open mind, but potentially have not taken part in a night time mountain trek before. Participants need a willing sense of adventure to explore the epic Snowdonia landscape by night. During the trek you will be supported every step of the way by our fully qualified Mountain Leaders.

You can tell your sponsors that on your Snowdon by Night Trek you will be:

  • Ascending and descending the highest mountain in England and Wales at 1,085m
  • Covering 9 miles of mountainous terrain
  • Starting your summit bid at 1am in the morning
  • Trekking under the cover of the night sky and guided by torch light

What is the terrain on the Llanberis Path
The terrain on this challenge varies throughout and can be rough at times, so preparation is ideal! Summiting Snowdon involves some steep ascents & descents and rocky terrain, however the Llanberis Path roughly shadows the route of the famous Snowdon Mountain Railway. It’s the most gradual route up Snowdon with good conditions underfoot, and therefore best suited to your ascent in the dark! There is an initial steep section which will afford some good views in in the moonlight; after this the route continues quite gradually. The path up the mountain will be quite obvious by torch light for most of the time though it is imperative to remain with your team and Mountain Leader at all times. Trekking at night is a very different experience than during the day; your senses will grow used to the darkness and you’ll enjoy the silence and the remoteness of this mountain, and the views of the impressive night sky. 

After the Halfway House the gradient becomes steeper in places, but you’re making good progress to the summit! You will pass through a narrow railway bridge, and it’s not long before you reach the Standing Stone, marking where other trails meet yours. A little further on you will arrive at the summit at 1085m with the glow of sunrise starting to linger. You would have gained approx. 900m in height since setting off – quite an achievement! 

After some time to experience the summit and hopefully a spectacular sunrise, your team will return to Llanberis the same way. The sky will start to lighten on your path down, and you may be able to enjoy the wonderful views over the Menai Strait towards Anglesey while you are still high enough to enjoy them. As the sun continues rise lighting up your surroundings, you will be amazed by what you climbed in the dark! The descent will be much quicker and less arduous, but still tiring and can be hard on the knees. You will reach Llanberis ready for a celebratory brunch! Brunch is at your own expense.

What are the group sizes?
Minimum group size of 8 people per Mountain Leader.
Maximum group size of 12 people per Mountain Leader.

Clothing and Equipment
Equipment of good-quality and durability could make the difference between a fantastic challenge experience and an uncomfortable one.

It is essential that all trekkers have a waterproof jacket with hood and trousers, hiking boots, warm clothing, a good head torch with spare batteries, beanie hat & gloves and be prepared for all weather conditions on the mountain.

Please ensure you are prepared for all kinds of weather conditions from cold wet & windy weather to warm sunshine on your descent. Despite your event being in late Spring, the weather is unpredictable in Snowdonia, particularly in the mountains. Please refer to your kit list and ensure you have the right kit to protect you from sun, heat, wind, cold and rain. Your kit will make your event either a great one or an uncomfortable one.

Closer to your trek date, feel free to check the Mountain Weather Information Service for Snowdonia for a descriptive weather forecast.

Adventurous Ewe prioritises the safety of all their participants and staff, and as such have developed a thorough safety management system. This encompasses comprehensive risk assessments and procedures together with audits of all aspects of your challenge from vehicles to accommodation to your activities.

Given this trek is held at night, you will be trekking the mountain in teams of 8 – 12 people and will be accompanied by a qualified Mountain Leader. Our Leaders are First Aid trained and have extensive experience in leading groups in the mountains. They will be ultimately responsible for your safety on Snowdon. They will be carrying full safety equipment and mountain first aid kits. Your health and safety is our top priority.

This is a tough challenge that will see you staying awake through the night. For this reason please factor in some rest before you travel home. If you have a long drive after the challenge you may also wish to consider staying an extra night.

Llanberis has a variety of different accommodation options. Please check VisitSnowdonia for a list of accommodation options.
