San Marcos La Laguna · Lake Atitlán · Guatemala
A mountain sanctuary for transformational retreats in Lake Atitlán.
Host your group, join a journey, or come experience the land through one of our upcoming retreats.
Every retreat begins as a seed.
A seed of growth.
A seed of compassion.
A seed of perspective.
A seed of evolution.
At Arco Isis, we care for those seeds through land, food, ritual, rest, movement, silence, and community.
And when you come back, you may find the tree already touching the sky.
