Unique or special yoga experiences in Sri Lanka (not just regular classes)?

Some retreats offer yoga on rooftops overlooking the ocean or tea fields, or at sunrise on beaches. A few places combine yoga with Ayurvedic treatments or meditation in historic settings. Sound healing and wellness workshops are becoming more common in the south and hill country. Look for smaller, boutique retreats rather than big hotels. Some guesthouses also organize special full-moon or sunrise sessions with local teachers.
