There are not too many limits to what you can do and experience in Ecuador, more than your own, and it is up to you to overcome them. We have seen so many participants coming to Ecuador with limited or no Spanish at all, but they made an effort to learn and were not shy to do mistakes or to talk to people, and they have had a great experience.
Don’t let the cultural and language difficulties be an obstacle, and you will experience a completely different life, meet friends and help out while having fun and learning Spanish.
