This is a manually curated list about the Best Yoga Retreats on Koh Samui, managed by Sophia Hughes.
We want our lists to be useful and accurate. If you have an established business that deserves to be listed here, please use this form to let Sophia Hughes know.
The short answer: Samahita is the strongest all-round structured retreat, Vikasa offers the most flexible class-rich yoga vacation, and Absolute Sanctuary has the clearest bundled yoga-and-wellness programme. Marga and Shahda suit travellers who prefer smaller-scale instruction, while Anahata combines yoga with a quieter Lipa Noi resort stay.
This guide includes Koh Samui properties that currently sell a residential yoga retreat, yoga holiday or retreat-style stay—not hotels that merely schedule an occasional class. Compare the exact teacher, practice time, class level, room, meals, transfers and cancellation policy. For wider choices, see our Thailand yoga-retreat comparison, Koh Phangan yoga guide and Thailand teacher-training comparison.
Detox, cleansing, weight-loss and healing language belongs to the provider and is not a guaranteed outcome. The NCCIH notes limited evidence and potential harms for commercial cleanses and colonic irrigation. Seek independent medical advice before fasting, restrictive diets, colon cleansing, intensive exercise or changing treatment.
Samahita Retreat
55/20-24 Moo 4 Namuang, Na Mueang, Koh Samui, Surat Thani, Thailand
Best overall for a structured retreat. Samahita publishes ongoing team-led yoga-and-fitness and yoga-breath-mind programmes alongside fixed-date guest retreats at its beachfront centre in southern Koh Samui. It has the clearest combination of current schedule, residential facilities and format choice.
The south-coast setting is quieter than the main resort areas, and content, teachers and intensity vary by date. Confirm the exact programme, room, meals, transfers, optional fitness and cancellation terms rather than assuming every stay has the same timetable.
Retreats Available at Samahita Retreat
Best for a flexible, class-rich yoga vacation. Vikasa offers choose-your-own-date Vikations with accommodation, two daily meals and access to its yoga timetable, as well as fixed retreats and teacher training. It suits travellers who want a larger yoga community and more daily choice.
Vikasa now promotes programmes at more than one property, and several current events are in Phuket. Confirm that the selected offer is at Koh Samui, plus the room, stairs and accessibility, practice level, meals and retreat schedule.

Absolute Sanctuary
88 Moo.5, Choeng Mon, Bophut, Koh Samui, Surat Thani 84320, Thailand
Best packaged yoga-and-wellness programme. Absolute Sanctuary in Choeng Mon publishes residential yoga programmes in five-, seven- and ten-day formats with accommodation, meals, classes, selected massages and airport transfers. It is a strong fit for travellers wanting one bundled resort programme.
The current package also lists colon hydrotherapy and other wellness treatments. These are not required for yoga and should not be assumed to detoxify or improve health; ask whether components can be declined and seek independent medical advice before invasive or restrictive services.

Marga Yoga
Marga Yoga, 276, Taling Ngam, Koh Samui, Surat Thani 84140, Thailand
Best small independent option. Marga Yoga in Taling Ngam currently lists Hatha, Yin and Yoga Nidra classes, SUP yoga, a six-day wellness retreat and teacher-training dates. It suits travellers who prefer a small operator and direct contact over a large resort timetable.
Some retreat dates on the site omit a year, so confirm the exact 2026-27 availability, accommodation partner, meals, group size and cancellation terms in writing. “Digital detox” is a programme theme, not a physiological detox claim.
Shahda Yoga
3/28 Moo 1, Fisherman's Village, Surat Thani 84320, Thailand
Best for intensive small-group instruction. Shahda Yoga advertises a seven-day residential package in Fisherman’s Village with meditation, extended yoga practice, accommodation and meals, limited to ten guests. It suits travellers who want close instruction and substantial practice time.
The programme is described as physically challenging, availability must be confirmed by email and payment is stated as non-refundable. Ask about modifications, the exact lodging, meal plan and current schedule before booking.
Anahata Wellbeing Resort
Anahata, 95/70 Lipa Noi, Surat Thani 84140, Thailand
Best for a quieter seaside resort stay. Anahata in Lipa Noi offers oceanfront rooms, yoga and movement alongside spa and retreat packages, with direct retreat enquiries and accommodation-booking routes. It suits travellers who want resort facilities away from Koh Samui’s busier eastern areas.
Many packages are marketed around detox, juice, weight loss or healing. Provider language is not evidence of medical benefit: confirm food intake, treatments, qualifications, exclusions and cancellation terms, and obtain independent clinical advice before restrictive diets or treatment changes.

Conclusion
Choose Samahita for the most balanced structured retreat, Vikasa for flexible dates and a large class timetable, Absolute Sanctuary for a bundled resort programme, Marga or Shahda for smaller-scale teaching, or Anahata for a quieter beachfront wellness stay.
Evidence was checked against current operator pages and live booking signals on 12 July 2026. Availability, teachers and inclusions change, so request written confirmation for your exact dates. Koh Samui’s weather and sea conditions vary by month and coast; check local forecasts and transport conditions rather than relying on a single Thailand-wide “best season.”
FAQs About Yoga Retreats on Koh Samui
Which Koh Samui yoga retreat is best overall?
Samahita is the strongest all-round structured option in this comparison. Vikasa is better for flexible dates and a larger class timetable, while Absolute Sanctuary offers the clearest bundled yoga-and-wellness package.
Are Koh Samui yoga retreats suitable for beginners?
Several publish beginner-friendly options, but not every class or fixed retreat is suitable for every level. Ask about pace, modifications, daily practice time, class size and prerequisites for the exact programme.
What is normally included in a Koh Samui yoga retreat?
Residential packages commonly include accommodation, yoga and some meals; transfers, spa treatments, fitness classes and excursions vary. Request the final written inclusions, taxes and cancellation terms before paying.
When is the best time for a yoga retreat on Koh Samui?
Use the confirmed programme calendar and current local forecast for Koh Samui. Rain, heat, sea conditions and ferry or flight disruption vary during the year, so there is no risk-free month that suits every traveller.
Are detoxes and colon cleanses necessary at a yoga retreat?
No. Yoga does not require a cleanse, and commercial detox claims are not established medical outcomes. Restrictive diets and colon cleansing can carry risks; ask whether they are optional and seek independent medical advice where relevant.
