15 Day Yoga Sadhana Retreat on Koh Phangan, Thailand

One Yoga runs the same ashram-style structure across three sadhana lengths on Koh Phangan — 8, 15, and 22 days — and this middle option is long enough to move past the adjustment period the shorter week barely allows, without the three-week commitment of the full sadhana. Days follow a fixed rhythm: yoga from 7:30-9am, a two-hour breakfast break, yoga philosophy at 11am, then Yoga Nidra, sound healing or meditation before a long lunch break and rest until 4pm, a second yoga session to 5:30pm, and silent meditation closing the day at 7pm. Eight styles rotate through the week — Hatha, Vinyasa, Ashtanga, Yin, Kundalini, Vipassana, Zen and Tantra — taught in open-air shalas with sea views on the beachfront campus.

Watch out: Meals are covered only Monday through Saturday — vegetarian and vegan breakfast and lunch buffets, with no dinner on any day and no meals at all on the Sunday rest day. Across 14 nights that adds up to real spending on dinners plus a full day of food, so budget beyond the retreat price. Taxi transfers from the ferry pier to campus aren’t included either.

Accommodation is air-conditioned for the full 14 nights, with both shared and private rooms available depending on budget. Fourteen nights is enough time that the daily rhythm stops feeling like a schedule and starts feeling like routine — long enough to actually absorb the philosophy classes rather than just attend them, which is the practical case for choosing 15 days over 8. It’s shorter than the full 22-day sadhana, though, for anyone not ready for a three-week stay away from home.

Beyond the two daily yoga sessions, pranayama work and a singing-bowl sound healing journey round out the practice side, and 30 days of free access to One Yoga’s online studio (900-plus classes) continues the routine after the ferry ride home. The all-levels billing holds up here: philosophy classes build understanding for newcomers while the range of eight styles keeps experienced practitioners engaged.

Insider Tip: Sundays are unscheduled and unfed on purpose — treat the day off as part of the design rather than a gap. Most guests use it to explore the island or simply rest, since Monday’s practice resumes at 7:30am regardless.

Getting to Koh Phangan means flying into Bangkok or Koh Samui and taking the ferry across, with no transfers included from either the airport or the pier. Free cancellation applies, though confirmation isn’t instant, so dates take a little time to lock in. The 8-day and 22-day versions run the identical daily structure at $299 and $797, so adjusting the length up or down doesn’t mean a different programme — just more or less of the same one.
