Why go

Homegrown trekking adventure

Since the COVID-19 pandemic hit our overseas adventures have unfortunately been on hold which has had a huge impact on local communities and livelihoods. However, we’re keen to promote adventures on home ground particularly to help support the local tourism industry whilst also giving you the chance to get out and explore our incredible Welsh landscapes in a safe manner.

This trek has been designed to deliver an amazing experience and showcase the some of the most epic mountain landscapes in North Wales whilst also giving you the chance to step out of your comfort zone and gain a greater understanding of the mountains, local environment and local communities.

Carbon Footprint

We’ve crunched the numbers to work out the total carbon footprint of the Welsh 15 Peaks Challenge, and plant or protect enough trees to suck 2x as much back out the atmosphere.

What’s the number?
It works out on average at 42kg of CO2 emissions per person, including all local transport, accommodation, food, activities, leaders, crew and office operations.

The only thing not included is travel to Snowdonia. Given that our beloved guests travel from all parts of the UK for this adventure we have no way of reliably knowing their travel plans therefore we’re unable to include an individual number in the figure on display here.

What does the number mean?
To give you a snapshot of the numbers:

  • Driving 1000miles/1609km would be approx. 281kg of CO2 in an average car (or 140.5kg per person if there was 2 of you).
  • A return economy class flight London – New York would be approx. 1,619kg (1.66 tonnes) per person.
  • 10 trees in a temperate forest are estimated to remove approx. 250kg of CO2 from the air over a period of 5 – 10 years.

 What are we doing about it?
Our adventures are relatively low-carbon by design, and we’re working to develop long term carbon reduction plan. Following much research into climate change organisations, we carefully selected to support the environmental charity, Cool Earth. They’re a sustainable operation and work with rainforest communities across the globe to halt deforestation and it’s impact on climate change. We invest 1% of our revenue into supporting critical conservation projects world-wild with Cool Earth.

On a local level, we’re an ongoing business member of the Snowdonia Society, plus Jim and Sue, together with some of our local leaders, also help the Society with their local projects such as planting native trees in Snowdonia. This is to help preserve the landscape and enhance wildlife habitat here in Snowdonia.

Want to know more?
We believe that with great travel, comes even greater responsibility. Tourism is one of the most important and largest industries on the planet. It employs more people worldwide than any other, with millions of families relying on tourism for their daily needs. At Adventurous Ewe we believe that our type of small scale, positive impact tourism can bring benefits to many communities, help preserve the environments we travel to see, and provide real and positive social exchanges. Here is our plan to do our part towards helping reduce factors that we can contributing to climate change as part of Tourism Declares a Climate Emergency.
