Cowley Manor Experimental in the Cotswolds stands out as one of the most distinctive spa hotels in the UK, thanks to its award-winning C-Side Spa, 55 acres of countryside and a spa menu powered by OSKIA and Biologique Recherche. This late-winter and early-spring season, the spa introduces a series of time-limited March offers, from International Women’s Day and Mother’s Day to St Patrick’s Day, Cheltenham race week and the first day of spring, plus an immersive Wim Hof session in the Victorian cascades, creating a truly singular wellness escape.
A countryside wellness hideaway in the Cotswolds
Just outside Cheltenham, Cowley Manor Experimental sits within 55 acres of private gardens, lakes and woodland, offering an instant sense of calm. Guests come for fresh country air, slow walks through the grounds, terraced water features and long views across the hills. The 17th-century manor house has been reimagined with playful interiors inspired by Alice in Wonderland, blending historic charm with contemporary design.
The 36 rooms and suites combine bold colours, graphic fabrics and considered comforts, many with views over the lawns and lakes. After a day of treatments or exploring the Cotswolds, returning to your room feels like slipping back into a private cocoon, with generous beds, bathrooms and little design details that keep the sensory journey going.
C-Side Spa: an award-winning spa among the gardens
C-Side Spa is Cowley Manor’s wellness heartbeat. Award-winning and instantly recognisable, it combines indoor and outdoor pools overlooking the landscape, light-filled treatment rooms, sauna, steam room and serene relaxation areas.
The treatment menu has recently been elevated with the arrival of OSKIA, a nutri-cosmeceutical skincare brand specialising in cellular skin nutrition, and Biologique Recherche, the cult French brand famed for its highly tailored protocols and immediate results. New face and body rituals blend indulgent textures, precise techniques and expert diagnostics for visible, long-lasting glow.
Between treatments, guests can drift between pools, alternate gentle laps with floating and simply pause to soak up the garden views. In the main house, Jackson Boxer’s seasonal menus and Experimental’s cocktails, including low- and no-alcohol options, extend the sense of a restorative stay well beyond the spa itself.
March spa offers: celebrating women, mothers, racing and the first day of spring
Throughout March, C-Side Spa marks key dates in the calendar with targeted offers that are perfect to gift or to enjoy for yourself.
Mother’s Day on 15 March becomes the ideal excuse for a mother and daughter escape. From 16th–19th March, when a mother and daughter book any one-hour treatment, they receive an OSKIA “perfect gift”, a skincare treat designed to extend the glow at home and keep the shared moment going long after they leave the spa.
During St Patrick’s Day and Cheltenham race week, the spa looks after racegoers and those seeking calm away from the course. From 9th–12th March only, guests who book any 60-minute treatment receive two hours of complimentary use of the spa, including pools, sauna, steam room and relaxation areas, turning a single appointment into a half-day wellness escape.
On 20th March, the first day of spring is all about renewal and choice. Guests can select three express bar treatments for the price of two, or enjoy a trio of express bar rituals for £75.00, building their own mini-journey, perhaps combining exfoliation, targeted massage and a glow-boosting facial.
Wim Hof in the Victorian cascades: a one-of-a-kind immersion
Beyond classic spa rituals, Cowley Manor offers a Wim Hof experience in the estate’s Victorian cascades, ideal for those curious about breathwork, cold exposure and mental resilience. From 2:00pm to 4:30pm, a guided session takes guests through structured breathing exercises, mindset preparation and controlled immersion in the cool cascade waters.
Priced at £30.00 per person, this workshop is available on a pre-booked basis and carefully supervised. The combination of stone, water and greenery creates a dramatic natural amphitheatre, while the proximity of the spa’s warm facilities means you can move from challenge to comfort in just a few steps.
Staying at Cowley Manor: extending the spa feeling across your stay
Choosing Cowley Manor as your UK spa base means embracing the full rhythm of the place. Jackson Boxer’s menus showcase seasonal Cotswolds produce from breakfast through to dinner, while the bar team mixes signature and alcohol-free cocktails that align perfectly with a wellness-minded escape.
Outside, 55 acres of gardens and woodland invite you to walk, jog, practise yoga on the lawn or simply sit by the lakes with a book. A short drive away, postcard-perfect Cotswold villages complete the picture with slow wanders, local shopping and historic sites. After that, it is back to C-Side Spa and your room, with the satisfying feeling that you have found one of the best spa hotels in the UK for time out alone, as a couple or with family and friends.

The mix of design, nature, facilities and treatment quality makes it a strong contender for anyone seeking a UK spa hotel with both character and substance.
Do I need to stay at the hotel to book the March spa offers?
The March offers are designed primarily with in-house guests in mind, but selected promotions may also be available to day guests, subject to availability. When you book, simply check whether you are booking as a resident or a non-resident so the team can advise on the best options.
How do I book a treatment or one of the seasonal offers at C-Side Spa?
You can book directly with C-Side Spa, either by phone or via the spa section of the Cowley Manor website. To secure the March offers or the Wim Hof session, it is best to reserve early and mention the specific promotion you are interested in, as spaces and timeslots are limited.
Is the Wim Hof session suitable for beginners?

The facilitator guides the group through the breathing exercises and cold immersion step by step, with adaptations possible according to individual comfort levels. It is important, however, to mention any relevant health conditions when booking.
Is Cowley Manor a good choice for a mother-daughter or friends’ spa break?
Very much so. The March mother and daughter offer with an OSKIA gift, the express bar combinations and the broader spa and dining experience make it ideal for a girls’ day or a weekend away. Between spa time, walks in the gardens and relaxed meals, it balances shared moments and personal space.
