Meanwhile, here's some teachers/venues I really rate that you can see if they have retreats on. What's lovely now with Zoom is you can try people out before you commit to a retreat.
Dhanakosha Buddhist Retreat- Scotland. This is where I did my first weeklong retreat, which was quite lifechanging about 15 years ago. Meditation, yoga, philosophy, freedom to reflect, experience silence, meet people from all walks of life, walk in amazing scenery. Refreshingly non-dogmatic and modest. Good if you're on a budget.
Alicia Ruiz Bustos & Didier Fernades. Wonderful authentic, experienced, intuitive couple that run yoga and detox retreats in India, Brazil, Spain and Portugal.
Ruth McNeil. A local, true yogi on and off the mat, experienced, caring, knowlegeable.
Mimi Kuo Deemer. One of my Teacher Training teachers. Combines yoga with QiQong. Experienced, authentic and knowledgeable.
Bridget Woods Kramer - Again, years of experience and a real pro.
Jeff Phenix - If you want strong sweaty practices
Karen John. A local, experienced teacher, very caring and knowledgeable
and many many more....
Alexandra Cat - The Yoga Clinic for students suffering from Complex Relational Trauma or Complex PTSD
