What people say about us
Thank you Nolan, Sam, Tuna, William and the whole staff for making me feel so welcomed and at home. Will be back again soon :)
If you're looking for a break from the world—to reset your body, clear your mind, and reconnect with what matters—The Sanctuary is a rare gem. Nestled in the lush jungle of Koh Phangan, on the beach of Haad Thien, this rustic and quirky retreat offers more than just detox programs and yoga classes—it offers space to breathe, a place to reflect and restart.
I came here for a 3½ -week stay that included a 5-day “Detox” and a 16-day “Reshape Your Life” fitness program, and I left feeling lighter in every sense: physically, mentally, emotionally. The location is both remote and magical—you reach it via a long boat ride, which already feels like a crossing into another dimension. Don’t expect marble floors or air-conditioned luxury; expect the raw charm of wooden bungalows in the trees, jungle paths, barefoot meals on the beach, and symphonies of cicadas and waves, a unique experience.
The wellness offerings are intense and immersive: daily colonics, shakes, massages, personalized fitness training, yoga and meditation classes. If you’re here to truly reset, this place gives you all the tools. The team, from the personal trainer Aunn to Waa and Janina and the other yoga and meditation coaches, to the wellness staff led by Boon, the wonderful restaurant staff led by Sam, Tuna at the reception and the incredible massage therapists—they all made the difference. Each brought warmth, skill, and genuine care.
A few things to note:
• This is not a party place. Nearby full-moon events and other parties can occasionally bring in sound from neighbouring beaches, but the Sanctuary itself remains focused on healing and stillness.
• The infrastructure is rustic. Don’t expect flawless Wi-Fi or five-star plumbing. But the simplicity grows on you.
• The food is exceptional. After detox, every bite of the fresh, healthy meals feels like a celebration. The wonderful setting of the restaurant on the beach, with the kind of view people use as screensavers, enhances every meal.
There’s also a unique community vibe. You’ll meet fellow travellers—some here to heal from burnout or depression, others seeking clarity or change. Some here for weeks or months. It’s the kind of place people return to again and again—often for years, sometimes for decades. Conversations go deep quickly.
Why not 5 stars? A few organizational kinks and some wear-and-tear infrastructure, likely due to staff turnover after the recent passing of the beloved GM. But none of that overshadowed the overall positive impact of this experience.
Come with an open mind, a willingness to simplify, and a deep breath. The Sanctuary won’t fix your life—but with their charming and knowledgeable help it might give you the quiet and clarity to start doing it yourself.
Eric B., Switzerland, Guest April–May 2025
You don’t simply arrive at The Sanctuary; you surrender to it. The boat journey to Haad Tien Bay becomes a gentle unwinding, each wave carrying you further from who you were when you left shore. When you step onto that pristine beach, something inside you exhales—perhaps for the first time in months.
I’ve watched this place evolve over twenty years, seen new faces become old friends, witnessed the careful dance between development and preservation. What strikes me most is how The Sanctuary has grown without losing its soul—like watching a beloved friend mature while keeping their essential spark intact.
The accommodation defies every convention of luxury travel. Forget marble bathrooms and thread counts. Here, your shower is beneath stars, your bedroom walls are living stone that has stood for millennia. The geckos darting across your ceiling aren’t intruders—they’re housemates, reminders that you’re living within something larger than yourself.
But perhaps the most transformative element isn’t the setting—it’s the people. The Sanctuary attracts souls in transition, hearts seeking something they can’t quite name. I’ve shared sunset conversations with artists rediscovering their voice, watched burned-out executives remember how to breathe, seen couples fall in love all over again. This trip, I brought my nine-year-old son Archie, and watching him embrace this magical chaos reminded me why I keep returning. Children understand what adults forget—that paradise isn’t perfection, but authentic connection.
The food isn’t just nourishment; it’s daily celebration. Each beachfront meal becomes a ceremony of gratitude, flavors so vibrant they contain sunshine’s essence. Conversations flow like tides, strangers becoming confidants over shared plates.
What The Sanctuary offers isn’t polished wellness—it’s something rawer, more honest. Yoga sessions happen as the sun paints impossible colors across the sky. Meditation workshops don’t promise quick fixes but something more valuable: permission to simply be. The healing programs understand that transformation isn’t about returning to who you were, but discovering who you’re meant to become.
True luxury isn’t what’s done for you, but what you discover about yourself. The Sanctuary provides the canvas; you create the masterpiece. Some guests plan two-week retreats and find themselves still there three months later, having found exactly what their souls were seeking.
Twenty years on, I still feel that familiar flutter as the boat rounds the bay. The Sanctuary isn’t just a destination—it’s homecoming to a version of yourself you’d forgotten existed. Where the world’s noise fades to whispers, time moves differently, and ordinary moments become extraordinary simply because you’re present enough to notice them.
This isn’t for those seeking conventional luxury or party thrills. The Sanctuary is for hearts ready to be surprised, souls brave enough to remember what peace feels like. For anyone suspecting the life they’re living might not be the life they’re meant for.
Some places visit you as much as you visit them. The Sanctuary has been a constant thread through two decades of my life’s tapestry, offering exactly what I needed—adventure in my twenties, healing in my thirties, perspective in my forties, and now, watching my child discover magic.
It’s not just a place I return to; it’s a place that returns to me in quiet moments when the world feels too much, reminding me that paradise isn’t about perfection—it’s about coming home to yourself
Wir waren in einem der Budget Bungalows, die zwar weiter hinten, aber immer noch sehr schön und hochwertig eingerichtet sind.
A special thanks to Sue, Abel, William, Sam, Tuna, Mey, Abale, and the entire crew for making everything perfect, and to the amazing teachers Randel and Nina for sharing their wisdom and guidance.
Staff are amazing (big shout out to Sami,Hong, Tuna, Abel, Wah Wah, May and Soe)
food is great the menu is extensive and interesting... A little pricey
There is a disco in the jungle on Friday night which is well publicised - either go dance or wear earplugs.... Don't complain about it. The Thais have to make a living as well!
The people are what make it special.. So don't tell anyone about Sanctuary when you leave.... Keep it the best kept secret
❤️❤️❤️
The Sanctuary changes its guests everytime I come but each set of people are remarkably similar to the previous - amazingly friendly and interesting folks
I can't imagine doing my annual recharge anywhere better
Waa is such a great yoga teacher, I enjoyed her classes so much. Nina is an amazing too, she brings joy to the yoga studio in a way no-one else does.
Hope I can get back there soon.
Ps: the first time I stumbled upon the sanctuary was in 2008! I promised myself I'd be back one day! Only took me 16 years!

Detox FAQ´s.
For optimal results from the program, we suggest reducing your caffeine intake, particularly coffee and black tea, to lighter options such as green tea or herbal tea at least 3-5 days prior to your arrival. Additionally, we recommend incorporating fiber-rich foods like vegetables and fruits as your main dish. And limiting your protein intake to a small portion on the side. Furthermore, it is advisable to avoid consuming simple carbohydrates like white flour, white rice, alcohol, and dried fruits.
In our daily lives, numerous factors can disrupt our detoxification, metabolic, and digestive systems. These factors may include stress, poor dietary and nutritional habits, lack of physical activity, environmental pollution, and personal crises. Living in a stimulating society can also have an impact. The consequences of these disturbances can be observed in your health and well-being. You may find that you cannot handle stress as effectively as before and experience anxiety and depression.
Your sleep patterns may be interrupted, and your elimination may not be as thorough, resulting in more gas, bloating, and indigestion than usual. These are early signs of reduced performance in your digestion, metabolic, and detoxification processes, leading to an accumulation of toxins and an imbalance in your gut flora.
If you are experiencing these symptoms, it may be time to detoxify your body. At The Sanctuary Thailand, a reputable detox retreat center with over 30 years of experience in fasting detox programs. We have helped thousands of guests from all over the world reset, rejuvenate, and achieve their wellness goals. We offer a full fast detox with herbal supplements, elixirs, and daily colonics. You can experience complete elimination and a feeling of wellness with our 3.5-day, 5.5-day, 7.5-day, or 10.5-day programs.
Colonic, also known as colonic irrigation, involves the infusion of water or other liquids into the rectum to flush out the colon. Advocates of the practice believe that it can improve digestive health and overall well-being. Prior to the procedure, a wellness consultant will typically conduct a consultation. Which will ask about your medical history and help complete wellness summary forms.
At our facility, we firmly believe that the colonic process is a personal one, which is why we require our clients to self-administer their colonics. However, rest assured that we provide detailed instructions on how to do it correctly, ensuring that you feel confident and comfortable throughout the process.
The terms “detox” and “cleanse” refer to dietary and lifestyle practices that help remove toxins or impurities from the body actively.
A detox program involves a short-term dietary plan that aims to eliminate toxins from the body, usually through fasting, juicing and supplements. The primary goal of a detox program is to rid the body of accumulated toxins and reestablish balance in the body’s systems actively.
On the other hand, a cleanse is similar to a detox but usually refers to a more long-term and sustainable approach to a healthy lifestyle. Cleanses typically involve making dietary and lifestyle changes that support the body’s natural detoxification processes. Such as eating a balanced, nutrient-dense diet, staying hydrated, and engaging in regular exercise.
Detox Retreat Holiday, available in various lengths ranging from 3.5 to 10.5 days. For an even more personalized experience, you can add special overlays to your program for only 700 baht per day.
If you’re looking for a more gentle approach, try our Gentle Cleanse program. It includes one meal per day and doesn’t involve colonics. As with our Detox program, you can also add overlays to tailor your experience.
Introducing our latest offer, Balance provides delicious and healthy meals from our cleanse menu that are tailored to your body’s specific nutrient needs. We offer keto, vegan, and pescetarian options, and all our meals are gluten-free, dairy-free, and free of refined sugar.

Our signature Detox program does not involve eating but instead provides fiber-rich drinks, juice, herbal elixirs, and supplements. However, you can enjoy a delicious vegetable broth in the evenings as a supplement to your cleanse.
If you’re looking for a more lenient approach, our Gentle Cleanse program allows for one meal per day.
Alternatively, our “Balance” program involves eating a standard amount of food to support your body’s natural detoxification processes.
