ONE Retreats

ONE Retreats runs 6-day residential psilocybin retreats at a beach-resort setting on West End Road in Negril, Jamaica, in small groups of around eight guests. The published program includes two guided psilocybin sessions alongside meals, excursions and integration support, with a pre-retreat virtual session with facilitators covering goals and health history, and a one-to-one session before the retreat. Scheduled 2026 dates published at the time of review: 26 September–1 October, 24–29 October, and 19–24 November.

The operator states that psilocybin mushrooms are legal in Jamaica, where all its retreats are held. Its published team includes co-founders Kevin Sean Bourke — described on the site as a Kairos Integration-certified facilitator and Vice Chairman of Jamaica’s Psilocybin Mushroom Technical Committee — and Vernise Cardillo, described as a certified psilocybin and breathwork facilitator; the team page also lists a Doctor of Nursing Practice with a stated two decades of mental-health clinical experience in a “journey nurse” role, a Taino ceremonial guide, a mycologist, and yoga and sound practitioners. The operator cites media coverage in outlets including Vogue and Rolling Stone.

Published pricing is USD $5,550 per person (approx. A$7,743*), with a $1,000 deposit and the balance due a week before the retreat.

This program is held in Jamaica, where psilocybin is not a prohibited substance. Psilocybin remains a prohibited substance in Australia outside the authorised clinical pathway. Australians travel at their own responsibility; this is not medical advice.
