What is a dark retreat?
A dark retreat is time spent in complete darkness, usually alone in a room or cabin built to keep out all light, with meals and support brought to you. It is best known as an advanced meditation practice from Tibet. Today it is also offered as a shorter, supported retreat for anyone who wants to rest deeply and look inward.
Dark retreat or darkness retreat?
They are the same thing. “Dark retreat” is the older name, the one used in Tibetan Buddhist and Bön teaching. “Darkness retreat” is what many modern retreats call it, ours included.
Either way, the defining feature is the same. For a set number of days you live in total darkness, sleeping, eating, resting and sitting in it, rather than closing your eyes for an hour and opening them again.
An old practice from Tibet
Dark retreat has long been practiced in Tibetan Buddhism and in Bön, the ancient Tibetan tradition, where it is an advanced practice within Dzogchen, the “Great Perfection” teachings. Traditional retreats commonly last from seven to forty-nine days and are undertaken with a teacher’s guidance. Accounts of Tibetan masters describe retreats lasting years.
The traditional teachings also carry clear warnings: extended darkness can unsettle someone who is unprepared. That is why the practice was taught with care, and why preparation, support and a gradual return to light still matter.
Chamma Ling, the Crestone retreat center where our retreats take place, was founded by the Bön teacher Tenzin Wangyal Rinpoche. Its cabins can be fully darkened, and meals come in through a small enclosed pass-through without letting in light.

What a modern darkness retreat looks like
Most dark retreats offered today are shorter and more supported than the traditional form: often three to seven days, in a private room or cabin, with food delivered, regular check-ins, and screening before anyone is accepted. The aim is usually rest, reflection and a stretch of uninterrupted attention rather than religious training.
Ours is a retreat of this modern kind. There is no teacher, no formal practice and no substances, and you don’t need any meditation or retreat experience. At Chamma Ling it looks like this:
- Four nights on site, about 72 hours of them in complete darkness
- Your own lightproof cabin, Standard or Premium
- Two warm meals delivered each day: a congee-based breakfast and a soup-based dinner
- A check-in with your facilitator every day
- A preparation call about two weeks before, a gradual emergence on the final evening, and integration support afterwards
What people notice
Without daylight, the day loses its edges. Sleep tends to find its own rhythm, and many people lose track of the hour within a day or so.
Many also see light where there is none: specks, colors or slow-moving shapes, the kind of activity the visual system produces when it receives no input. It is a well-known effect of prolonged darkness.
The bigger change, people often say, is how quiet it becomes once there is nothing to look at, and how much surfaces in that quiet: memories, feelings, questions set aside for years. That is much of the point, and it is also why support matters.
“No substance, no teacher, no practice to follow — just me and the dark. Because of that, the insights and revelations I received felt undeniably my own.”
Is a dark retreat safe, and who is it for?
Dark retreats are safe when they are thoughtfully designed, properly screened and supported by experienced facilitators. They are not for everyone. Retreat providers commonly advise against them for people experiencing psychosis or mania, and anyone living with a serious mental health condition should talk with their clinician before booking.
A dark retreat suits people who are comfortable spending time alone and reflecting on their own experience. It is not therapy or medical treatment, and it does not replace either.
We speak with everyone before accepting them, screen for fit, check in every day during the retreat, and offer integration support afterwards.
How to prepare for a dark retreat
In the days before, reduce stimulation and media, adjust your diet, and set a clear intention for your time in the dark. You are welcome to bring snacks, a journal, an instrument and comfort items; a Mindfold mask is recommended for extra light protection.
Once you are accepted, we send detailed preparation guidelines, and about two weeks before your retreat you have a one-hour call with your facilitator. On arrival day your facilitator shows you the cabin, the blackout setup and the ventilation fan with the lights on, so you know the room by hand before the light goes.
How long is a dark retreat, and what does it cost?
Traditional retreats run from seven to forty-nine days. Modern ones range from a single night to several weeks, with three to seven days common for a first retreat. Ours is four nights on site, with about 72 hours in complete darkness. For some people we may suggest a different length, depending on readiness, intention and experience.
Our spring 2027 retreats run back to back from March 15 to April 12 in Crestone, Colorado, on a sliding scale: $1,600, $2,000 or $2,500 for a Standard cabin, and $300 more for the Premium cabin. Every guest receives the same retreat, whichever rate they choose.
