Live and unleashed

music festival
The Big Top Marquee and the Band Stand.

Big Top Marquee

Vacant Weekend | Steel Foxes | Bossyking | Foxtrap | The Northern Threads | State of Satta | Delagrave | Thieving Magpies

Band Stand

Joel Gardner | Clara Pople | Hang Dimension | Ewan Scarlett | Stoney Broke | Jordan Worsfold | J Lewis | Chloe Jane Hirst | Open Folk Session

Each of these stages will see a showcase of incredibly talented, local music acts. Importantly, having two stages will also enable a more continuous live music experience to be delivered from early afternoon till dusk, plus offer protection against any adverse Cumbrian weather. And for the first time, there will also be live music during the day on Sunday at the Band Stand which will be located in the heart of the reimagined food and drink zone.

So, expect chilled out vibes and acoustic sets there, while you unwind after your sporting exertions. Or if you’re feeling the adrenaline, head into the Big Top for some electric performances.

Keswick is located in the heart of the Lake District and is the Outdoor Adventure Capital of the UK. Keswick is very accessible by all means of transport, meaning that you can consider the environment when planning your route to Keswick Mountain Festival.

Festival campsite

The KMF campsite is located at Springs Farm, Springs Road, Keswick CA12 4AN, only a 15 minute walk away from the Festival Village on Crow Park.

festival campsite

Camping is the best way to enjoy the festival, getting back to nature and sleeping in the fields, wake up to the view of Skiddaw – it doesn’t get much better. Facilities include showers, toilets, cafe serving hot food/drinks every day. Tents only, no campervans/motorhomes.

A weekend camping ticket includes 3 nights camping from 10am Thursday to 5pm Sunday and a car parking space.

accessible camping

By car

From the M6 (traveling both North or South) take Junction 40 at Penrith for the North Lakes. From J40, follow the A66 West for approximately 17 miles to Keswick.

By bus

With a timetable, and a little planning, you can reach Keswick Mountain Festival and many other beautiful Lake District places by bus. If you are a walker, you can use the bus to complete a linear walk without the necessity of having to return to where you left the car.

These are the services to consider:

  • Penrith to Workington – Service X4, X5
  • Lakeslink – Service 554, 555
  • The Honister Rambler – Service 77, 77A
  • The Caldbeck Rambler – Service 73, 73A
  • The Borrowdale Rambler – Service 78
  • Keswick to Patterdale Ullswater Connexion – Service 208

By rail

Penrith, Carlisle and Kendal (via Oxenholme) are served by the West Coast Main Line – a fast, frequent and easily accessible service from all over the country. The nearest railway station to Keswick is Penrith, a distance of 17 miles. A bus service (journey of approx 40 minutes) connects Penrith railway station with Keswick Bus Station. Alternatively you can pre-book a taxi from Penrith train station to Keswick.

The historic Settle to Carlisle line brings passengers from Yorkshire via the Eden Valley.

The West Coast line is operated by Virgin Trains.

By plane

Manchester Airport and Newcastle Airport both offer convenient access to the North of the UK. Manchester serves more domestic destinations than any UK airport which, together with its first class road and rail link make it an ideal gateway to Cumbria.

Manchester Airport has its own railway station, with direct links to Oxenholme – the Lake District, Kendal, Windermere and the West Coast Main Line. Newcastle Airport also has good road links to Cumbria and the Lake District.

Race location

The Festival Village is located in Crow Park adjacent to The Theatre By The Lake. From the Festival Village walk down to Derwentwater shore where the event will start.

Route overview

All of the open water swims take you out toward Derwent Island in a clockwise direction and then back in towards Crow Park. The beauty of Derwentwater and its surrounding views of Catbells, Skiddaw and the Borrowdale Valley will make this swim a memorable experience for all participants. This 750-metre event will turn around before reaching the island.

A deep-water start will take you across to the shores of Derwent Isle, before swimming clockwise alongside its shores overlooked by the historic Island. Finish under the gantry back at the Festival base with an excited crowd ready to cheer you home. 

Pre-event training in the water is recommended.


KMF swims will operate under British Triathlon Rules with regards to water temperature and the wearing of wetsuits. Under these rules the water temperature must be 14oC before wetsuits become optional.

Water quality

Derwentwater has a history of Blue Green Algae presence in the water and over the past few years,  with warmer winters, the bacteria which causes this is not always killed off over the winter months. It is therefore possible for blooms to occur as the temperatures rise in the Spring. (Many of you will remember that in 2019 the Keswick Mountain Festival swims were cancelled due to very late blooming of the algae. This is something we do not wish to see repeated.) We work closely with National Trust and the Environment Agency who help us to monitor the water in the run up to the Festival and inform us of any potential blooms.

Blue Green Algae is present in many water courses and not all forms are toxic. The greatest risks of a toxic algae are for animals and young children who drink water containing the algae and, in the case of dogs in particular, may pick up algae on their coats and then lick their coat, thereby consuming even more.

Blue Green Algae forms as a localised bloom, meaning that large parts of the lake can be unaffected even if it is present in some areas. Even when present, it is entirely possible to swim in Derwentwater without ever coming into contact with the algae.

What do we do if there is blue green algae in the water at the time of the Festival?

We will test the water, with support from the Environment Agency, in advance of the Festival and we will identify and monitor where the blooms are. If we find there are blooms of Algae in the water we will conduct a full analysis and amend courses if needed, so we are satisfied that the routes used in the KMF swims and the triathlons are safe for swimming.

Doing good

KMF is on a mission to do some good. A mission to make the festival more sustainable, accessible, inclusive and diverse, as well delivering a positive impact for the people of Keswick.

Alongside National Trust, the charity partner, a new sustainable legacy project with Fix the Fells. Everyone who is coming to the Festival is invited to help on that journey. The aim is to raise £10,000 per year, which will cover the annual cost for the Catbells conservation work. You’ll be able to donate at checkout on the website when buying your tickets. Please do so if you can. Catbells provides the stunning festival backdrop and helping to preserve this national, natural treasure is a wonderful thing to be part of.

The Festival works with venues and stakeholders in Keswick, to integrate aspects of the festival into the town, especially the evening programme. So, when the live music stops on Crow Park at 9:00pm on the Friday and Saturday, the ‘after party’ can continue in restaurants and bars throughout Keswick, boosting the benefits for the local economy.

A message from the Festival Director:

It was a big call to take a break from the full multi-sport festival, but it gave us the ideal opportunity to take a deep look at what we want this event to be in the longer term. Keswick Mountain Festival is very special to us and to many of you who share our love of this wonderful part of the world and the outdoors in general. We took the time to reflect on all of that and on the changing nature of big events.

There are now new and very different challenges involved in delivering a festival like ours in a responsible and sustainable way. We’re really excited about how we’re tackling those head on, in a way that still offers all of the aspects that our regular visitors tell us they love so much, and more. It’s going to be a vibrant, multi-faceted and inclusive event for everyone, and we can’t wait to welcome you all back in May. Nicola Meadley
