5 Day Cleanse and Detox Program on Koh Phangan, Thailand

Orion Healing Centre runs this 5-day fasting and colonic-cleanse program from a retreat centre on Sri Thanu Bay, on the west coast of Koh Phangan. It combines a liquid fast with daily colemas, herbal detox drinks, and one 1:1 health consultation, and it is priced from around $692 for 4 nights. The program suits first-timers as much as repeat fasters — the wellness team walks you through the colema process rather than assuming you already know it.

The Program

Day 1 is the pre-cleanse: two liver flush drinks — fresh orange juice, lime juice, garlic, ginger, and olive oil — spaced through the day, alongside alkalising meals to prepare your gut for the fast. Days 2 through 4 are the fasting days proper: four detox drinks a day built on bentonite clay and psyllium husk to bind and move waste, green superfood supplements, probiotic implants, one fresh coconut, herbal tea, and up to two self-administered colemas a day using your own private equipment (coffee, apple cider vinegar, or garlic additive options). A daily wellness meeting checks in on how you’re feeling and adjusts the pace if the cleanse is hitting hard. Day 5 is break-the-fast day: a final probiotic implant, then a light reintroduction meal — papaya bowl, smoothie, or raw soup — before checkout.

Insider Tip: Ask for a room away from the shared colema station if you’re a light sleeper — the fasting days involve early starts, and Orion’s compact site means some rooms sit closer to the wellness lounge than others.

Setting

Sri Thanu is Koh Phangan’s quieter west coast — no Full Moon Party crowds, a handful of yoga shalas and juice bars, and sunset views over the Gulf of Thailand. Orion’s own grounds include a herbal steam room, infrared sauna, ice bath, and a wellness lounge where guests decompress between detox drinks. Hin Kong Beach is a short walk south if you want sand and shallow, calm water during your free time.

Who It’s For

Best suited to guests who want a structured, supervised way to try fasting for the first time, or who’ve fasted before and want the added push of colon cleansing. It is not a beach holiday with wellness extras bolted on — expect hunger, some fatigue on days 2 to 3, and a genuinely different focus to a typical yoga retreat. Anyone with a history of eating disorders, is pregnant, or has a chronic digestive condition should check with a doctor before booking a multi-day fast.

Meals & Inclusions

There’s no solid food on the fasting days by design — nourishment comes from the detox drinks, herbal tea, one elixir a day, and fresh coconut. The 4-night stay, daily yoga classes, a 60-minute oil massage, a 60-minute Reiki treatment, sauna and ice bath access, and pre/post-retreat support from the Orion team are all bundled into the price. Wifi and luggage storage are included; airport transfers, flights, travel insurance, the visa fee, and any optional on-site workshops are not.

Practical

Book through Orion’s 12-day Vitality Juice Detox instead if 5 days feels too short to properly reset — it is run by the same team on the same site, with a longer post-cleanse transition. Free cancellation runs up to 60 days out, and confirmation is not instant, so allow a few days for Orion to reply once you book.
