Private Psilocybin-Assisted Wellness Retreat in the Costa Rican Mountains

The retreat runs three days, with the psilocybin journey on the middle day. Day one is preparation: you sit down with Sebastiaan and work out what you actually want to look at, what you want to understand or change, and what might come up emotionally when you do. You'll also do some bodywork — Rebalancing®, the modality he trained in over three years in the Netherlands — which is less massage and more noticing where you're holding tension and what happens when you let it move. Meals are cooked by Anaïs and you eat when it suits you.

The second day is the journey itself. You take psilocybin in a private, supported setting with Sebastiaan present throughout. There's no pressure to have a particular kind of experience — the point is that you're not left alone in a difficult moment, and there's no expectation that it needs to look like anything. Afterwards there's time to rest in the cabin, walk the property, or sit by the river. The day isn't packed.

Day three is integration. You go back through what came up — with Sebastiaan talking it through, and with self-inquiry and coaching to connect it to your actual life rather than leaving it as an interesting experience you had in Costa Rica. There's more bodywork if it's useful. Before you leave you'll get a written Progress & Integration Report, and an online session follows a few weeks later once you're home and the material has had time to settle.

What separates this from a group psilocybin retreat is that it's entirely private. You're not sharing a ceremony circle, you're not working to a group schedule, and there's no need to manage how you appear to other participants. The trade-off is price — this is a one-to-one programme, and it costs accordingly. It's also not a clinical trial or a medical treatment; it's a guided, trauma-informed retreat, and Sebastiaan's background is in bodywork, meditation and psychedelic guidance rather than psychiatry.

The location is Pejibaye, in Pérez Zeledón canton, about 3.5 to 4.5 hours by road from Juan Santamaría International Airport near San José. The property sits in the mountains with a villa, a private cabin and a river at the bottom of a short jungle path. Days are quiet — bird noise, mountain air, and not much else. If you want a schedule packed with activities, this isn't it.
