For a weekend of Ashtanga, Iyengar, Hatha or any other flavor of yoga or meditation, head for the hills about 45 minutes northwest of Fort Collins. The 600 acres of Shambhala Mountain Center have provided a setting for contemplative Buddhist retreat since 1971; after three years of expansion and development, the good folks there are reaching out to non-sectarians in search of a mindful resort. Weekend yoga and renewal retreats are offered about twice a month during the summer, with a range of accommodations available. The spectacular mountain setting and the wisdom of the staff welcome all into the nurturing atmosphere. In addition, the Great Stupa of Dharmakaya -- the largest Buddhist shrine in North America, fourteen years in the making -- is now open for tours on weekends.
