A lot of churches and spiritual retreat centers have labyrinths. Some are public, some private. Some are made of vegetation, others stone. I love that each labyrinth is unique.
I live in the U.S., but I love that labyrinth-walking is an activity I can do on most trips.
These are some bucket list labyrinths, but I love that there are labyrinths all over the place. You can even build your own with some rocks or sand.
