10-Day Plant Medicine Retreat
With Karina Mariaca de Oliveira and Hilvert Timmer
January 16 - 25, 2026
Pisatahua Ecolodge is a sacred space in the Bolivian Amazon to work with plant medicines, including ayahuasca. Found in the heart of the Aquicuana Reserve, our 80-hectare center is situated in an area of impressive biodiversity. This breathtaking location provides an ideal environment to heal, expand consciousness, and connect with the wonders of the Amazon.
We organize master plant ceremonies, with medicines including ayahausca. We facilitate shamanic diets to learn and heal with traditional plant medicines in close consultation with our healers. We organize small-group retreats to ensure that each individual receives the personalized attention they require.
This 10-day plant medicine retreat offers a deep inner journey towards connection, integration and healing, as a rite of passage towards sustainable improvements in daily life. The dialogue between the spirits of human and plants teaches us to listen, providing a connection to heal our common world.
