weekthun circle

Meditate for a week or the full month of Dathun,
a retreat in the Colorado Rocky Mountains

Weekthun is an intensive, week-long meditation retreat for new and experienced meditators interested in deepening their mindfulness-awareness. As part of the month-long Dathun program, there are four successive Weekthuns which can be taken individually or in combination. Through these immersive weeks, the practice of meditation goes beyond the cushion, with every aspect of daily life becoming a practice of wakefulness and an opportunity to make better friends with ourselves and our world.

Nestled high in the Colorado Rockies in a serene 600-acre valley surrounded by rocky peaks, pine and aspen forests, Shambhala Mountain Center provides an inspiring, safe and supportive container for fully immersing yourself in meditation.
