Route and Terrain

Our journey to Black Moss Pot begins on a rather pleasant, mostly level gravel track that runs alongside the beautiful River Derwent. As we push further into the valley, the path gradually becomes rougher underfoot, challenging us with loose stones and some muddy sections, especially after a good downpour. The final approach to the pot itself requires a short, steep scramble over rocks, so do watch your footing and ensure you have plenty of grip. The return route often follows a slightly higher path, where we've encountered a few boggy patches after wet weather. It’s certainly a moderately hilly walk with varied surfaces, and you'll find it's not really suitable for wheelchairs or pushchairs. Remember, the path is very stony in places, making sturdy footwear absolutely essential, particularly as straying off the main line can lead to very boggy ground.

Sights & Experiences

Black Moss Pot itself is a truly hidden jewel, a deep, emerald-green plunge pool nestled within a dramatic, high-sided rock gorge. When we were there, the water was incredibly clear, allowing us a tantalising glimpse into its depths. The surrounding fells are a stunning tapestry of heather and bracken, creating a real sense of being deep within a secret world carved by water over millennia. Along the way, we passed the enchanting Fairy Glen, also known as Galleny Force. This magical spot features a series of crystal-clear pools and cascading waterfalls, offering a tranquil place for a paddle or a moment of quiet contemplation amidst the trees and moss-rimmed steps. It's a truly picturesque detour.

Hidden Gems

Don't rush past Fairy Glen and Galleny Force on your way to Black Moss Pot! We found these beautiful lower pools a perfect spot for some pictures and a refreshing dip, especially if you're looking for a slightly gentler swim or if Black Moss Pot is a bit too busy. They offer a lovely woodland experience with smaller waterfalls and serene pools, making for a truly magical interlude. If Black Moss Pot is crowded, we've discovered that heading a little further upstream past the main pot reveals several other gorgeous, quieter pools perfect for a peaceful swim, though they aren't quite as good for jumping.

History & Heritage

While the focus here is undoubtedly on the natural beauty, the village of Stonethwaite, our starting point, holds a quiet charm. Keep an eye out for Stonethwaite Bridge, a lovely single-span packhorse bridge that crosses Stonethwaite Beck. Dating back to the late 18th or early 19th century, it’s a humble but enduring piece of local history, built from local volcanic stone to serve the packhorse and farm traffic of the isolated Borrowdale hamlets.

Seasonal Changes & Best Time to Visit

The best time to tackle this route is undoubtedly between April and October. During these months, the water feels a little less bracing and the sunlight truly brings out the vibrant emerald colours of Black Moss Pot. Be aware that after heavy rain, the paths can become particularly wet and marshy, and stream crossings might be more challenging. While thrilling, the water is always cold, so we always advise taking precautions against cold water shock, even on a warm day.

Parking & Public Transport

Parking around Stonethwaite can be a bit of a challenge, so we always recommend arriving early. There are a few very limited free spaces by the iconic red telephone box in the village (CA12 5XG), and some roadside parking spots on the grass before the school. When open, a dedicated day parking field past the school often operates for around £5, which is helpful to manage traffic.

Safety & Preparation

Sturdy, waterproof hiking boots with excellent grip are absolutely essential, as the terrain is rocky, uneven, and can be slippery or boggy. If you're planning a swim, always check the water depth and for submerged hazards before entering, and acclimatise gradually to avoid cold water shock.

Difficulty & Alternatives

We'd class this walk as easy to moderate overall, but the rough, stony, and often boggy terrain, coupled with the steep scramble down to Black Moss Pot itself, means it's not really a route for young children. For families looking for a dip, the Fairy Glen offers a much more suitable and safer alternative. While much of the initial path is fairly level, the uneven surfaces and potential for wet ground require good fitness and sure-footedness.

Insider Tip

In my humble opinion, Black Moss Pot offers the absolute best plunge pool jump in the entire Lake District. The sheer thrill of launching yourself into that deep, emerald water from the high cliffs on the far side is an unforgettable experience, especially with good friends! Just make sure you've checked the water first.

Recommended Shops & Pit Stops

After a invigorating walk and swim, the traditional Langstrath Country Inn in Stonethwaite provides a welcoming spot for refreshments. It’s always a good call for a post-walk pint or a bite to eat. If starting from Rosthwaite, you'll find public toilets conveniently located adjacent to the National Trust car park.
