Retreats are a big business today, A quick google will bring up dozens of possible retreats focusing many interests and needs. Fasting, Pilates, Grief, Fitness, Therapy, Recovery, Wellness, Couples, Men’s, Women’s, and Educational are some of the broad strokes of retreats. They can be found around the world and in your own backyard. Fees can be really high or manageable for the retreatant with modest means and reasonable expectations.
Spiritual retreats are available for the current spirituality craze. The major world religions have provided retreats for many years. Christians have benefitted from the Catholic and Episcopalian retreat tradition. My first exposure to retreats was as a member of Reba Place Fellowship.
