Retreat to the magical Helford River with an enchanting stay in a beautifully handcrafted
Cornish treehouse. With a name that means ‘calm’ in Cornish, Kalmynsi is a secluded haven that can’t help but spark the imagination, from the captivating curve of the treehouse
to the idyllic setting in which it sits. A canopy of oak, beech, and ash wraps around the
cedar-clad treehouse in a leaf-strewn embrace, inviting you to step away from the everyday and
reconnect with nature. Stroll through the dappled wonderland that surrounds the Helford River,
before sinking into the fire-warmed depths of your sunshine yellow outdoor bathtub as birds sing from the
trees. Perfect for romantic escapes in this ancient corner of Cornwall, and you can bring the dog
for dappled adventures across the halcyon landscapes of South Cornwall.
Kalmynsi Treehouse
3.4 miles W of Helford
Sleeps 2 | dog friendly
Treehouse in Cornwall with a wood-fired outdoor bathtub: Surrounded by rolling countryside that gently weaves into ancient woodland, Kalmynsi invites you to uncover the secrets of the Helford River with your dog by your side, before retreating to a tree-lined haven of your own.
Overview
Step Inside
Before you even enter your Scandi-inspired hideaway, Kalmynsi crafts an air of whimsy through
woodchip paths and beautiful arches woven from the branches of surrounding trees. Kick off
your boots in the porch area and step through the door to find a stylish and peaceful interior you
simply won’t want to leave.
Wood-clad cabinets and crisp, white counters create a sleek kitchen, kitted out with an electric
oven and induction hob, toaster, and dishwasher, making culinary crafts a dream. A small
fold-out table beckons for leisurely mornings spent enjoying pastries while watching the gentle
buzz of the natural world.
The kitchen transitions into the living space with effortless ease. Pop a disc on the beautiful,
yellow Crossley record player and sit back in the comfy Graham and Green armchair as the
pooch dozes by the wood burner or lounge on the matching sofa in front of the smart TV. Books
and games are on hand to provide endless entertainment, or you can simply sit and soak up
your serene surroundings as the musical stylings of The Hollies fill the air.
In the bedroom, lush linen drapes over the sumptuous king size bed, promising a deeply restful
slumber to set you up for a day of exploring. As birdsong fills the air and the morning sun
sparkles through the branches, step onto your private balcony for a blissful start to your day, or
pull on your complimentary robe and follow the path to your dreamy wood-fired outdoor bath. The
bedroom boasts lots of hanging space for your clothes, as well as a lovely dressing table and
stool.
Continuing Kalmynsi’s soothing neutral tones, the luxurious bathroom beckons for relaxing
moments, with a rainfall shower and heated towel rail adding those special luxury touches.
Outdoors
Carved into the hillside, Kalmynsi’s outdoor area invites you to bask in the joys of outside living
as you enjoy fireside moments and soothing soaks in the wood-fired outdoor bathtub. Step onto the paved platform
to find your blissful, sunshine-yellow outdoor bathtub waiting to wrap you in a fire-warmed embrace. A
lovely handcrafted seating area gathers around the chiminea, promising soul-warming evenings
toasting marshmallows in the dancing flames as stars shine overhead.
Explore
With the wood-topped charms of the Helford River on your doorstep, Kalmynsi is perfectly
placed for leaf-strewn adventures with the pooch. A stone’s throw from the treehouse, the
Cornish Seal Sanctuary is a wonderful, dog-friendly day out and helps to support the amazing
rescuing and rehabilitation of seals around Cornwall. The Helford River is a magical mix of
serenity and adventure, inviting you to find your own way to enjoy the ancient woodlands that
wrap around the ebbing waters. Enjoy peaceful riverside walks along Frenchman’s Creek, or
take to the water in a kayak or sailing boat and discover secluded beaches perfect for a picnic
full of local produce.
A little further, you’ll leave the dappled trees behind as the landscape flows into the rugged
cliffscapes of the Lizard Peninsula, where beautiful beaches and salt-kissed walks await. A
stone’s throw from the pretty harbourside town of Falmouth, Kalmynsi promises a heavenly mix
of historical sites, golden sands, and sub-tropical gardens, from Pendennis Castle to the
kaleidoscopic scenes of Trebah Gardens.
South Cornwall is home to an abundance of mouthwatering eateries, from Michelin star
favourites in Falmouth to the many heartwarming pubs along the Helford River. Visit The
Shipwrights Arms in Helford village for tranquil waterside meals, Slice of Cornwall near

We absolutely loved our stay in this treehouse – it genuinely exceeded all expectations. From the moment we arrived, it felt like luxury on stilts. Every detail had been thoughtfully considered, from the record player to the extra touches like outdoor cushions, a picnic set, and additional bathrobes for the hot tub. The kitchen was incredibly well equipped, and the welcome book was both helpful and beautifully put together.
The quality and finish throughout were exceptional, and the sense of tranquillity made it feel like a real escape. The bed was super comfortable, and the shower was excellent – everything you’d want after a day exploring.
The location is perfect as a base for discovering some of the best of Cornwall, but honestly, the highlight was the secret outdoor garden. It felt private, spacious, and really special – a true hidden gem.

Spending Christmas 2025 in this stunning treehouse was hands down the best holiday decision we’ve ever made. It turned a festive break into real magic—peaceful, luxurious, and very special.
Perched quietly on a hillside among beautiful woodland, the treehouse feels like a hidden gem. It’s beautifully designed with thoughtful details, stylish and high quality, and incredibly comfy from top to bottom. The interior feels warm and inviting, the bed is heavenly, and it’s all equipped for a perfect self-catering stay.
The private hot tub was the absolute highlight—set in a nicely kept garden, so private and super comfy. Evening soaks under the stars, with a glass in hand, became our nightly ritual and a total mood booster.
The nearby village felt wonderfully cosy and festive, with a handy pub and a great farm shop. It’s handy for Helston, gorgeous beaches, and coastal walks
If you’re after a unique, tranquil luxury escape—this is it!
