You are in good hands with these guys. I did a 10 day retreat back in March this year. I am not going to go into details about the actual Aya / San Pedro experience witch was amazing. The whole ECA team are incredible you feel the second you meet the guys that they have found their calling in life and genuinely enjoy facilitating these incredible medicines.
In regards to the price, yes there are cheaper places available around south america, but i can honestly say that its money well spend. In this case you really get what you pay for. I have done a retreat in Peru previously to this one, and the food, accommodation, medicine was way superior with ECA compared to the other place i tried. Don’t be a tight ass when it comes to something like this. I promise you its the best investment of your life!
All in all 11/10 to ECA changed my life 🙂
