Outdoor fans can help the Envirotrek effort by heading to Snowdonia next weekend

Outdoor enthusiasts are being offered the chance to clean up the countryside in a national park and enjoy a range of activities.

Organisers of the Envirotrek series are looking for people to take part in next weekend’s event in Snowdonia.

Rock climbing, high ropes and water activities are on offer for those taking part in the Llanberis clean-up, and there will be a chance to win prizes provided by sponsor Keen, the footwear brand.

The Respect the Mountains Envirotrek events are taking place across Europe, with the British leg taking place next Sunday, 24 May.

A spokesperson for the organisers said: “The Envirotrek is a fun grassroots initiative, involving tourists, local volunteers and businesses that addresses this need, providing a feel good community experience, simply ‘spring-cleaning’ the mountain environment and hiking through the hills to see who can collect the most litter.

“During the 2014 series, some 613 volunteers signed up over six events, amounting to a monumental 1,220 hours of hands on clean-up time in the hills. Their brilliant efforts resulted in a jaw-dropping 5,120kg of waste being cleared – including 459 refuse sacks and an assortment of waste being removed from the mountains.”

This year marks the 7th consecutive season of the Envirotrek Clean Up Series, and takes place across various European mountain destinations including the United Kingdom, Germany, the Netherlands, Czech Republic, Austria and France.

The family friendly programme at Llanberis will kick off about 10am, with volunteers walking a track and collecting rubbish and waste.

Group leaders are allocated and all participants will be provided with cleaning and safety equipment and fully briefed with a safety talk. The clean-up finishes at around 12.30pm, with volunteers being rewarded for their mornings’ efforts with a barbecue lunch on the hill.

Participants then get to spend the remainder of the afternoon enjoying a range of fun outdoor pursuits organised by the Envirotrek leaders, which will include climbing, rope climbing and a water-based activity. Organisers said: “There’s even a chance to win some great prizes including Keen footwear and gifts for the best or most unusual rubbish found – previous candidates have included mattresses and even a car door – with the day’s event closing at approximately 4pm.”

Entrance for this event costs £10 per adult and £5 for children under 12, who must be accompanied by an adult, though is free with those showing proof of purchase of a pair of Keens in the last 30 days. You’ll need to show your receipt.

Meeting point is Padarn Adventures, Padarn Country Park, Gilfach Du, Llanberis, Gwynedd, LL55 4TY. Places can be booked online.

Robust, comfortable footwear is recommended and participants are advised to bring water, sunscreen and an all-weather jacket.
