Faith-based travel is a niche that continues to grow by leaps and bounds, and tour operators are constantly updating their offerings.

Travelers are more frequently looking to make a spiritual connection when undertaking a journey and oftentimes, religion and faith-based experiences can give greater meaning to a trip.

When travelers think of faith-based travel, however, they often connect these trips to spiritual journeys to the Holy Land or an "Eat, Pray, Love" type adventure, but there is surprising diversity in destinations where religion, culture and history collide.

One of the most exciting faith-based experiences is the Oberammergau Passion Play, which takes place once a decade, with its next performances scheduled for 2020 in Oberammergau, Germany.

The best way to obtain tickets and experience the play is to visit with a tour operator. A number of operators, as well as river cruise companies, are offering Oberammergau already. Tickets frequently sell out, so if this is something on your bucket list, booking now is advised.
