Summit Day

You will meet your leader team in the town of Llanberis for registration and the all important safety briefing. 

The route takes us up and down the Llanberis path, a distance of 15km and with almost 1,000m of ascent to reach the summit.

You will be supported every step of the way by fully qualified mountain leaders.

Reaching the summit is sure to be a special moment, and hopefully the weather will provide us with spectacular views of the surrounding landscape.

How tough is it?

The Snowdon Challenge is graded as challenging. This is the perfect challenge for participants who are of an adventurous spirit and an open mind and who wish to push themselves in one of the UK's most iconic landscapes. You can tell your supporters that on your Snowdon Challenge you will be:

  • Trekking for around 7-8 hours in a single day
  • Covering 15km of mountainous terrain
  • Trekking without support, carrying all your food and water for the entire day
  • Ascend 1000m in a single day
  • Summiting one of the UK's highest mountains, and the highest peak in Wales!

Training

Training advice is readily available.

Group size

During the course of the trek it is very likely that you will split into smaller groups, but at all times you will be accompanied by one of our qualified mountain leaders.

 

Dogs

Unfortunately, you are unable to walk with your dog. This is due to safety reasons for your fellow hikers and your dog.

Terrain

This challenge takes place on a well maintained footpath. However, the path is rocky in places and can be slippy if wet. Certain sections of the path are steeper than others but there are no sections that require you to use your hands to scramble.

 

Food and drink

A packed lunch to take with you on the trek is included in the cost however you are encouraged to bring some of your own preferred snacks to keep you going during the challenge. 

Please bring enough bottles to ensure you have 2 litres of water on you at all times. 

Please ensure you have had a substantial breakfast before arriving and that your water bottles are already filled.

  • Sustainability policy

This challenge should have a positive impact on the communities visited and is committed to sustainable and responsible tourism. It aims to make sure that impact on the local environment is minimised.

Summary

You can help achieve this goal by:

  • Adopting a policy of ‘leave no trace’.
  • Taking all litter off the trek with you, including fruit peels and skins.
  • Using public toilets when available and take any tissues from ‘wild wees’ home with you.
  • Stick to the footpaths at all times and avoid walking on their edges, to help prevent erosion from spreading.
  • Only using the car park(s) designated for your event, and not parking on the local streets.
  • Keeping noise to a minimum when passing houses in residential areas.
  • Leaving rocks, plants and other natural objects as you find them. Please don’t take these home with you.
  • Avoid transporting and introducing invasive species by cleaning your outdoor gear regularly.
  • Contributing to the local economy by paying for parking, staying an additional night in the local area or enjoying a local meal out.
  • Being patient and understanding if at points you have to wait or slow down due to others being on the same path.

You are asked to think carefully about any memorial-type activities you may plan for your challenge. It is fully appreciated that this challenge has emotional importance and encourages you to mark that special moment in your own way, whilst ensuring that the natural beauty and protection of the environment you’re in is maintained. Leaving photos or other memorabilia or writing on stones is contrary to the leave no trace principle.

Remember: ‘Take only memories, leave only footprints’.
