I can not recommend the team at Harmonica highly enough! What a truly profound and spectacular week. Oliver has created a fantastic team/family. Magical week, magical location/view, the activities, the food, the people, the vibe. Wouldn’t change a thing and definitely going back. The relaxed atmosphere mixed with the integration after the retreat is so comforting. Far more than I could ever have imagined!

Incredible retreat center run by warm, knowledgeable, caring folks. Oliver, Kevin, Jenna, Sergio, and Luna (and the rest of the large team) are exceptional people: mindful, smart, and highly expert in leading these retreats. This is NOT easy work -- for the participants, nor for the facilitators. But thanks in great part to their wonderful work, I had one of the most meaningful and transformative experiences of my 58 years.The setting is beautiful (and only an hour from central Medellin). The food was hearty and healthy, and the my room was a serene cabin-like one with a shared terrace overlooking the valley and mountains.The ayahuasca experience itself was filled with beautiful music, respectful ceremonial aspects (Sergio leads these incredibly well), and a great deal of planning and pre-work with each participant. We had 12 participants in our sessions (from all around the world) and 6 facilitators and staff to take care of us and lead us: a really great ratio, especially for the low $$ price of this experience.

This was a wonderful experience. I truly found myself in Colombia at an Ayahuasca Retreat. Oliver and his team are simply amazing. It was the first time in a long time I actually felt safe. I highly recommend this place if you lost in world or floating in the abyss. It is life changing and you won’t regret it.
