22 Day Yoga Sadhana Retreat on Koh Phangan, Thailand

One Yoga’s 22-day sadhana programme on Koh Phangan is the longest of three lengths the school runs on the same beachfront campus — 8, 15, and 22 days, priced from $299, $548, and $797. The extra three weeks buy more repetition inside the same fixed daily structure rather than a different or more advanced syllabus: yoga from 7:30–9:00, a philosophy class at 11:00, yoga nidra, sound healing, or meditation around midday, a long lunch break and rest from 13:30–16:00, a second yoga session from 16:00–17:30, and silent meditation closing the day at 19:00.

Classes rotate through eight styles across the week, from Hatha and Vinyasa through to Kundalini, Vipassana, Zen, and Tantra, held in shalas with sea views on the beachfront property. Accommodation is air-conditioned throughout the 21 nights, with private or shared rooms depending on availability. Guests also get 30 days of free access to One Yoga’s online studio — over 900 classes — to keep practicing after the ferry ride home.

Watch out: Meals only cover breakfast and lunch buffets, and only Monday through Saturday. Dinner is excluded every day, and nothing is provided on the Sunday off — across 22 days that’s a larger stretch of meals to plan for independently than on the shorter programmes, simply because there’s more calendar to cover.

Insider Tip: Three weeks is a real commitment to one fixed schedule — anyone unsure about the length is better off testing the format on the 8-day version first, since all three run an identical daily structure and the shorter stay is a lower-cost way to find out if the rhythm suits before booking three weeks.

Beyond accommodation and the listed meals, the package includes daily pranayama sessions and a singing-bowl sound healing journey. Airport transfers, flights, taxi transfers from the ferry pier to campus, visa fees, and any activity outside the programme are excluded, alongside weekend and non-teaching-day meals. Free cancellation applies to the booking, though confirmation isn’t instant, so it’s worth allowing some lead time before dates lock in. At 4.79/5 from 280 reviews, the volume of feedback is substantial for a three-week commitment, suggesting the format holds up for people who choose it deliberately rather than as a first yoga trip.
