WHAT YOU CAN EXPECT
The Hermes Retreat, organized by Ikaros Project, creates spaces where daring to look deeper opens new ways of experiencing life. Our legal psilocybin retreat offers a space for expansion and renewal, supported by integration coaching and expert talks that bridge psychedelics with art, science, embodied practice, spirituality, and the deeper questions of being human. Once you arrive, it’s important that you feel seen and cared for. Our facilitators are here to support you, to answer practical questions, offer emotional guidance, and ensure your personal needs are met with attention and care throughout your stay.
ACCOMMODATION
We host our retreat in a spacious and welcoming mansion, beautifully set in the rural area near Castricum, in the Netherlands. The venue is located within a protected nature reserve - just step outside the door and you’ll find yourself in the dunes, and with a short walk beyond, at the sea.
Each participant has their own private bedroom, offering space to rest and integrate. Bathrooms can be shared or ensuite, depending on availability, with ensuite rooms available for an additional fee.
