What is now Crater Lake, the deepest lake in the entire country, was once volcanic Mount Mazama. Due to a spectacular eruption, the mountain essentially blew its top off and became the giant crater that we see today. Eventually it filled with water, which is how we now have the beautiful and sacred Crater Lake.
For hundreds of years, if not thousands, the lake has been a holy site for Native Americans, particularly the Klamath tribe. Making dangerous and heroic spirit quests to the lake has been part of Klamath traditions for centuries and still continues to this day.
Visiting Crater Lake National Park can be a deeply spiritual experience, just for the sake of spending time in nature by the lake. You won’t find many retreat centers here, like you will in other places on this list. That said, this ideal for travelers who feel most spiritual when connecting with nature.
