9 Day Enriched Full Fasting Detox Retreat in Koh Chang, Thailand

The Spa Koh Chang Resort’s nine-day program is the longer of the operator’s two fasting retreats, built around seven full days of fasting rather than the shorter package’s three — a stretch supported entirely by structured cleansing drinks, with no conventional meal service during the fast itself. Group programming runs on twice-daily self-administered colon cleansing (the colema system), plus daily rounds of a 60-minute massage or spa treatment, a 30-minute abdominal detox massage, and a 30-minute herbal steam bath or far-infrared sauna — each repeated seven times across the stay.

The Spa Koh Chang Resort is the base for the full 8 nights, in private accommodation on Koh Chang. Beyond the treatment schedule, the package covers pre-cleanse guidance, a personal detox orientation, and daily program supervision with on-call assistance throughout — support that matters given the length of the fast. A breaking-fast kit and herbal supplements are included to manage the return to solid food once the seven fasting days end, and the 600 THB coupon stretches across pre-cleanse meals, post-cleanse food, and additional juices.

Watch out: a seven-day fast is a materially longer commitment than the operator’s 5-day juice fasting retreat, which fasts for three days at roughly half the price. Anyone without prior fasting experience, or with underlying health conditions, should weigh the shorter program first rather than starting with the longest fast the resort offers.

Dietary accommodation extends to vegetarian, vegan, organic, and raw food preferences for the pre- and post-fast eating windows, though during the fast itself the cleansing drinks are the only intake. Treatment volume adds up across the nine days: seven hours of massage or spa treatment, three and a half hours of abdominal work, and seven rounds of sauna or steam — all layered onto the twice-daily colon cleansing sessions, which require comfort with a self-administered procedure.

Airport transfers, flights, and travel insurance are excluded from the price, along with additional activities or treatments outside the set itinerary. Free cancellation applies up to 30 days before arrival. Reaching Koh Chang means flying into Trat and taking a ferry across, or travelling overland from Bangkok — roughly 4-5 hours plus the ferry crossing either way.

Insider Tip: the pre-cleanse phase is where the 600 THB food coupon gets used — spending it on light, easy-to-digest food before the fast begins makes the seven fasting days noticeably easier to get through.
